Semiconductor relays for electric vehicles

Semiconductor relays for electric vehicles are cutting-edge switching devices that control high-power circuits in electric vehicles using high-speed, high-durability semiconductor elements, rather than conventional mechanical contacts.
Without contacts, they virtually eliminate wear and failure, boasting fast switching speeds, long lifespan, and outstanding reliability.
 
In particular, compared to conventional power-free IGBTs, they significantly reduce power loss at the same current (100A) by approximately 1/6, enabling efficient energy management.
Thanks to these advantages, they are gaining recognition as a key component in electric vehicles.

ESS thermal runaway prevention device

By monitoring battery temperature and various sensor data in real time, it can predict internal temperature and calculate the risk time and level, which can be utilized for fire prevention and mitigation.
 
It predicts the risk of lithium battery fire and provides an estimated time of occurrence (up to an hour to several minutes in advance). It also visualizes changes in risk levels in a graph and provides immediate notification via a remote audible alarm.
These features enhance battery safety and effectively prevent accidents such as fires.

Electric vehicle brake energy recovery

The brake energy recovery system in electric vehicles is called a regenerative braking system.
This technology converts kinetic energy when the vehicle decelerates into electrical energy and stores it in the battery.
