(picture source: Eaton official website) according to foreign media reports, Eaton company (Eaton) has launched a high-voltage circuit protection solution for electric vehicles, integrating fuses, ignition switches and contactors into a single coordination device. Now, the power of the electric vehicle is constantly improving. The circuit breaker solves the problem that fuse and contactor are difficult to coordinate, and provides extremely fast, safe and reliable protection for high-power and inverter system. This circuit breaker can start up to 1000V and 30000a in less than 5ms. Compared with the traditional circuit protection method, it can further improve the safety of the vehicle and protect the components more effectively in case of over-current. Like the circuit breaker, the circuit breaker can be reset. After the functional check, the equipment can be reactivated to reduce costs for manufacturers and consumers and improve customer satisfaction. Eaton uses its industrial technology and automotive expertise to develop the circuit breaker, which can improve the performance and reliability of the car while also providing architectural simplification. "In the event of a collision, Eaton's circuit breakers can work with the vehicle safety system," said Jeff lowinger, President of Eaton's mobility business unit. Regardless of the state of danger, it can quickly disconnect the high-voltage battery from the rest of the car, greatly improving safety and protection. " The circuit breaker also has the following advantages for the convenience of electric vehicle manufacturers. It includes: a self triggering device, which can sense the current spike and interrupt the circuit; in the short-circuit state, it provides the current limiting function and improves the system protection level; it is independent of the current direction and allows full load charging and driving; moreover, it has a variety of configurations, including voltage level and multi pole structure.
