ProtectionEnvironmental

The environment, energy conservation and carbon reduction are topics of serious concern to stakeholders. Chroma has been advocating environmental protection and energy conservation for a long time and makes sustained effort to lessen the impact of greenhouse gases and global warming. In addition to innovative research and development in the manufacturing processes of our advanced equipment and measuring instruments, we also pay serious attention to lessening the impact of our products on the environment. We reduce energy use and waste generated in production to a minimum.

We have implemented the concept of green product design at every stage of the R&D of new products. This starts with customer demand and includes the e-management programs. The R&D division has been tasked with making the products more energy-efficient and ensuring compliance with hazardous chemical regulations. We use renewable and recyclable materials as much as possible. Improvements and evaluations are carried out on a continuous basis to ensure that our mass production meet the requirements and standards in terms of quality assurance and environmental protection. We conduct sampling inspections to ensure the products remain in compliance with the requirements. Our aim is to ultimately implement sustainable product management.

The company has also been promoting various energy-saving projects in the factories. These include the production lines, offices, public areas, IT center, etc. The company expects to achieve a substantial reduction in energy consumption by optimized energy management. We expect to achieve the goals of sustainable coexistence with the environment by using highly efficient environmental improvement technology and equipment. 

Currently, the company and subsidiaries of the Group have been taking part in green and environmental protective activities. We have taken an aggressive approach to develop operations and products that are more eco-friendly. In this way, we seek to satisfy the green requirements of our customers as well as the regulations on management of energy and resources, climate change, RoHS and toxic chemicals in the countries where we sell our products. We use this as a guide for improvement and sustainable management to eventually become a totally green company.

Chroma will keep improving energy saving, carbon reduction and environmental management in all our factories. We are actively focusing on green design and production, and the reduction of GHG emissions. We are determined to establish proper green management and lessen the impact of our products on the planet and are steering our suppliers in the same direction.

Climate Action

Responses to Climate Change and Management of Energy and Resources

The use of energy and resources not only consumes the total mineral resources of the planet, but also produces a tremendous volume of greenhouse gases such as carbon dioxide, the primary component. Global warming has increased the occurrence and intensity of extreme weather and in addition to sometimes irreversible damage to the planet, this can seriously affect our manufacturing environment. In the face of global climate changes and ecosystem transformation, we need to take immediate action in the management of energy and resources, as well as greenhouse gas emissions.

Chroma established a GHG inventory system four years ago, and created an inventory process for the detection of all possible sources of GHG emissions in our organization. Each year, we check the GHG inventory for the previous year in our factories under Category 1 and Category 2. A third-party certification organization carries out the inspection in accordance with ISO14064-1. We fully understand the greenhouse gas emissions condition of the company and formulate the short-, mid-, and long-term reduction plans according to the individual amount of emissions to company implement our planned actions on environmental protection.

Using the data from the 2018 ISO 14064-1-based GHG inventory, we calculated the GHG emissions from the use of energy in our Linkou Headquarters and branches in Hsinchu and Kaohsiung. The sources covered by the inventory included externally purchased electricity, equipment for processes, boilers, water towers and water chillers. The total emissions were 11,096.987 tons CO2e with an average of 6.471 tons CO2e per employee. The overall emission density was a 6.47% increase from 2017, due to the difference in product category and manufacturing processes. The main source of emissions was externally purchased electricity under Category 2, which accounted for 97.40% of the total emissions. In the future, we will continue the inventory of our GHG emissions and take relevant measures for emission reduction.

Waste Management

 

Waste disposal has become a serious environmental issue. Waste is a threat to the environment and it also results in huge waste disposal costs for both the enterprises and government units. Statistics show that Chroma generated that a total of 275.52 tons of waste in 2018. The waste generated in the factories can be divided into general business waste and hazardous waste. These are properly sorted and stored individually. Cleanup plans are regularly submitted to the environmental protection agencies in the areas where Chroma operations are carried out.

Professional and legally recognized cleanup, disposal and recycling companies are commissioned and strictly monitored, for the disposal of the waste produced by the company to ensure proper and safe waste treatment. Furthermore, only 1.86% of the waste generated by Chroma is hazardous. Due to the nature of the industry 98.14% of the companywaste is general business waste. The company will actively reduce the amount of waste generated by optimization of production processes and use of recycled materials.

We have promoted comprehensive sorting, management and collection at the source to optimize resource recycling. Useful resources are sold or delivered to certified treatment companies for recycling to make effective use of them and increase the benefits of recycling. 

Moreover, the company will actively reduce the waste generated by the optimization of production processes, a reduction of the amount of raw material used, and the use of recycled materials. We continue to raise the awareness of our employees to the benefits of resource sorting and recycling and the positive impact such practices have on them as well as the company. We hope to strengthen the idea of resource recycling amongst our employees and encourage spontaneous maintenance and implementation of the idea in a continued effort to reduce our impact on the environment.

The places where toxic chemical substances are used in the company are in accordance with the regulations of the Toxic and Concerned Chemical Substances Control Act. We have obtained the related documents issued by the competent authority and hold toxic chemical training courses every year. In 2019, we will promote the self-management of toxic chemical substances, establish hazard prevention and simulate a response rehearsal plan to ensure proper operation and reduce the risk of hazards.

The operations are conducted according to the related government 
regulations. We have devoted much effort to the prevention of pollution and harm to human health from leakage. We have also promoted reduction management measures and computer controlled operations:

Measures to Improve Energy Saving in the Factories

 

Enhance air conditioning systems in the factories

The company buildings need a lot of air-conditioning. The water chillers 
consume the most energy and account for 60% of the AC system energy consumption. Enhancement of the water chiller efficiency not only saves energy but reduces electricity costs while reducing the carbon dioxide
emissions as well. In 2018, the company replaced the air-cooled water chillers on the fourth floor of the Headquarters building. Water pumps and sprinkler pipes have been installed in the AC system tanks in the head office. The ice-cold water from the bottom of the tanks is pumped to the sprinkler pipes and sprayed evenly on the top of the ice layer. This circulation effectively solves the problem of ice melting in summer, reduces the amount of power consumed by AC during peak hours, and eases the pressure on the Taipower energy supply. Replacement of the water chillers raised the energy-saving efficiency on a single floor of the head office building by 18%, and the estimated total energy saved was as much as 35,040 kWh, with a cost saving of NT$105,121.

 
The replacement of the time controllers in the factory cleanrooms

Factory cleanrooms are essential for certain production processes. The 
cleanness of these environments needs to be maintained for long periods. However, work in the cleanrooms is not continuous over the 24 hour day. After consultation with the units concerned, automatic time controllers were installed in 2018, which have greatly reduced cleanroom energy consumption. Some of the servers can even be shutdown. This has not disturbed the proper operations and production requirements continue to be served while cleanliness has been maintained. Statistics show that energy saving efficiency reached 96,969 kWh in 2018, with a saving of NT$290,907 in electricity costs.

Temperature settings of the air conditioners in offices

As a response to the Bureau of Energy regulations on energy saving, the 
factory affair units are watching the ice storage systems. Central monitoring ensures that the temperature of the water from the melted ice can be PID-controlled and the office temperature is kept within the range of 25 to 26°C. This saves energy and reduces carbon emission. and the temperature difference between the office and the outside is not likely to
cause discomfit in people moving in and out.

Plan for our new premises as a gold-class green building

To increase production capacity, construction of the new A7 building was 
started in 2017. The lighting will be fully LED-based, and the design of the building will allow efficient collection of rainwater. This is used in a sprinkler irrigation system and also for sanitation purposes. The lower floors have ice storage air conditioners, and the upper floors VRV high-performance air conditioners. Arrays of solar panels will be installed on the roof. The curtain walls use double-layers of Low-E energy-efficient glass to reduce the burden on the air conditioners. In addition, hanging gardens will be set up in the factories. We expect to receive a gold-class label for green building. This highly intelligent green factory clearly demonstrates our commitment to becoming a sustainable, green enterprise.

At the “2017 Summit on Innovation and Development of Automotive echnology in Taiwan ”, our Turnkey System Business Unit presented the outcome of the research and development on the automotive platform designed by Hua - chuang Automobile Information Technical Center Co. (HAITEC), whose R&D teams are dedicated to locally developed cars in Taiwan. The presentation focused on power systems for electric vehicles. In Manager Tseng’s words, reduction of carbon emissions is the common objective of countries around the world, and Taiwan cannot stand on the sidelines. The S3 EV+ intelligent electric car of the local brand Luxgen is the first of its kind to be 100% designed and manufactured in Taiwan. It plays a pioneering role in efforts to reduce carbon emissions in the country.

In the industry chain of power systems for electric vehicles, we are focusing on motor controllers. We have actively cooperated with HAITEC in developing a motor controller exclusively for S3 EV+. The power of the controller is 150 kW with at least 97% efficiency and power density of up to 15 kW per liter. Regarding reliability and safety, the most important indicators of automobiles, our motor controller passed tests on international car standards and gained the status of a world-class product. Through collaboration with the industry, universities and academia, we have formed a coherent and strong ecosystem team. In recent years, electric cars have become a global trend. In 2017, 1.22 million electric cars were sold worldwide, a 58% increase from 2016. The top 5 countries in terms of the number of sales were China, US, Norway, Japan and Germany. Many countries have been active in formulating policies in relation to electric cars. Norway was the first country to set the goal of full electrification of commercial cars by 2025. The UK and France announced that sales of purely diesel-powered and petrol cars will be banned in 2040. Carmakers around the world have also developed their responses to these policies.

As a result of the efforts of Chroma and members of the local automotive R&D team, including the Industrial Technology Research Institute, Automotive Research and Testing Center, National Taiwan University, National Taiwan University of Science and Technology and National Taipei University of Technology, we have been able to rely on so many experts and technologies with respect to HAITEC’s automotive platform and complete the development of the power systems, which were successfully integrated with S3 EV+, the first locally designed and manufactured electric car. For the auto industry in Taiwan, it was a milestone on the road to a whole new lifestyle that is eco-friendly, high-tech, green and intelligent.

Leading Development in the Electric Motorcycle Industry by Collaborating with Research Institutions

The government plan that in 2035 all new motorcycles will be electrical has stimulated the development of fast-charging systems for batteries, and electric motorcycles have become a global trend. Chroma leads collaboration between industry and research institutions, and is working with the Industrial Technology Research Institute (ITRI), Ship And Ocean Industries R&D Center (SOIC) and eTreego Co Ltd. The results of research into "an electric motorcycle charging station and charging compatibility test systems" were officially announced at the Taipei International Electronics Show on October 9, 2018.

The Chroma electric motorcycle charging station and charging compatibility test system is based on the "industrial standards of the fixed type inductive charging system for electric motorcycles" developed by the ITRI. It can simulate charging station conditions, or an electric motorcycle with normal or abnormal charging modes as well as the testing parameters, on electrical characteristics and communication. This will assist manufacturers with product testing in the R&D stage and before product delivery, and also allow the management and monitoring of production. ITRI has created a technical blueprint for testing regulations as verification of the technology and foundation of product testing. Supported by the Department of Industrial Technology (Ministry of Economic Affairs), Chroma, SOIC and ITR have all collaborated in the development of the charging interface simulator used in this testing system. And eTreego’s charging module and the design and development of capable charging stations, as well as the collaboration between the industry and research institutions has made a serious contribution to the development of domestic electric motorcycles. 

This has also improved charging safety and enhanced the popularity of electric motorcycles. The charging infrastructure is the key to the popularity of electric (motor) vehicles. There is much support for the potentially huge domestic market as a result of favorable policies and regulations. Chroma has been devoting much effort to the green energy industry and the measurement and testing of key components of electric vehicles. This includes the testing solutions for the carried charger, AC and DC charging station, battery power, battery management system and motor stator, which have now been adopted by domestic and overseas vehicle manufacturers and well-known inspection laboratories. In addition, we have established the first electric motorcycle charging station and a charging compatibility testing platform that meets the domestic testing regulations, and have created another business opportunity.

Battery Testing Equipment- Leading the Market

Outstanding Efficiency in Energy Conversion and Much Lower Cost of Production
6-3-1-en.png
Parallel connection allows the support of device under test with different power

The battery modules are available in high-capacity, low-capacity and other forms. If tests are conducted on high-power equipment with a low-capacity battery module, the accuracy of the tests is clearly not enough. With parallel connection, the battery module is able to set the parallel channels whose number is based on the actual capacity of the module. Replacement of equipment is not necessary, and the event where the accuracy fails to meet demands will not occur.

To ensure energy transition and tackle the increasingly severe problem of air pollution, last year the Executive Yuan decided that government cars will become fully electrified in 2030. The Executive Yuan also decided that motorcycles and cars using fuel oil will be banned in 2035 and 2040 respectively. It means that starting from 2040, all vehicles in Taiwan will only be powered by electricity.

Chroma is a manufacturer of electronic measurement and automatic testing equipment, and a provider of turnkey solution services regarding power cells for electric vehicles. As the number of delivery of Tesla’s newest affordable electric car Model 3 reaches its peak, the demands for electronic tests also keep rising. In recent years, we have put efforts in the development of measurement technologies for electric vehicles and launched a battery discharge control module. As a response to certain energy issues, our Model 17020 System was designed in a way to enable energy recycling. The electrical energy discharged from the battery pack is recycled and used as domestic power or directly transferred to any other battery pack that needs recharge.

For battery testing, we have designed some functions out of safety consideration. There are functions for detection of overvoltage, overcurrent and other abnormalities during the testing process to make it safe. In addition, there is a data preservation mechanism. These functions will bring great benefits in the future. For example, if the amount of energy consumed per hour is 12,000 kWh, with 90% efficiency in energy recycling, Model 17020 is able to reduce the annual carbon emissions by 90% (about 57,993,408 CO2e), and our customers will save about NT$0.4 billion in electricity expenses every year ( calculated based on NT$2 per kWh ) . We maintain high efficiency and low costs for our customers in order to make the prices of our products more competitive. We are also committed to energy and power saving to protect the environment and do our part to help Earth.

Renegerative Energy Battery Module Testing System

The Chroma 17040 high precision battery module testing system is an efficient and very safe charge and discharge device especially developed for the testing of high-power secondary battery sets. It also has a regenerative function that routes the discharge power back into the grid, providing clean and stable power.Efficiency is 90% or higher to save energy and lessen heat dissipation. The electric grid remains stable even during dynamic charging and discharging and it does not affect other equipment with harmonic pollution. The energy produced during discharge of the battery set is recycled to the electric grid, which solves issues of traditional equipment with waste of discharge energy and space heat treatment. The requirements of environmental protection are fully met. 

The 17040 also has a dual-mode feature. This allows switching to battery simulator mode giving real battery characteristics for motor driver or charger testing.

The 17040 system allows parallel connection and a dynamic driving profile simulation function. The parallel connection function allows higher charge/discharge current and power, this increases the efficiency and flexibility of the equipment to achieve high utilization. The simulation function of the dynamic operating condition allows loading of the battery waveform of a given driving profile, and the current/power mode meets the NEDC and FUDS standards. The dual direction structure ensures that the instantaneous current is not interrupted during the charge/discharge transition moment, so that the driving conditions can be precisely simulated. This meets various international test standards such as ISO, IEC, UL and GB/T. 
The 17040 system includes Battery Pro software which has a flexible editing feature. Independent tests can be conducted for each channel to meet the various test requirements for all secondary battery sets. 

Various safety and protection mechanisms that reinforce battery test risk management are included. The testing process will automatically detect abnormality such as over-voltage, over-current, over-temperature and any external parameters. Should an abnormality be detected in a channel, the protection mechanism
will be triggered to stop charge or discharge. The 17040 is highly stable and safe and supports a power failure recovery feature to ensure that test data will not be interrupted or lost.

Enhancing the Quality and Safety of Battery Management Systems for Electric Vehicles

There has been a global realization of the urgent need for zero carbon emission in electric vehicles. The battery is the key component and the performance and safety of the battery pack is crucial. The core battery management system (BMS) requires specific and detailed verification to ensure safety. The Chroma 8710 BMS automated testing system (ATE) provides voltage and temperature sensor simulations for a BMS. Furthermore, it offers applications suitable for the Unit Under Test to reduce the problems when performing the tests.

The BMS usually includes a current sampling unit (CSU), battery cell sensor circuit (CSC) and battery management unit (BMU). It delivers information to the BMU via CANbus signals and issues appropriate operational processing commands. When verifying a BMS, it is imperative to verify the cell status monitored by CSC as well as the active/passive balancing circuit and current consumption. For the CSU, the validation of current sampling accuracy is essential as it may affect the battery SOC, SOH and over-current protection function. As to the most complicated BMU that controls the entire system, it verifies the data returned from CSU and CSC.
