Electric Light Truck Project in South Korea With Our EV Systems
Project Overview
In 2021, an electric truck manufacturer in South Korea approached us for EV systems to support their electric light truck project. After a thorough analysis of their vehicle requirements and specifications, we recommended a range of EV systems including air conditioning compressors, water pumps, DC/DC converters, and EHPS. We then customized these systems to perfectly align with their vehicle platform. By 2023, the prototype had successfully entered mass production, and we continued to supply additional systems to meet their growing needs.
Challenges Faced
During the project, the client considered changing their voltage platform, which would have required adjustments to our products. However, after careful evaluation by engineers from both sides, it was concluded that maintaining the original voltage platform would be more beneficial. The client ultimately accepted this recommendation and kept the original platform unchanged.
Another challenge was the client’s requirement for the CAN protocol to be based entirely on their standard frame, whereas some of our systems used extended frames. To ensure the project’s success, our engineers customized the CAN protocol, adjusting both the content and communication speed to meet the client’s standards.
How We Worked
To ensure our systems work well on the client’s electric light truck, we modified the water pump bracket to fit the electric light truck chassis. During vehicle installation testing, our engineers provided remote technical support, assisting the client in modifying the software protocol and completing the full vehicle testing.
