In case of serious collision of electric vehicles, electric leakage and fire are very dangerous. It is reported that in the event of an electric vehicle accident, once the air bag is activated, the microchip in the electronic control unit will trigger the explosive power-off device within one millisecond. Recently, Bosch, a component company, has made another breakthrough in this explosion technology, which helps to improve the safety performance of electric vehicles and reduce the risk of battery leakage and fire. In fact, most of the common electric vehicle voltage platforms are 400V, and the latest taycan model is 800V. If the battery is damaged in an accident, the high-voltage electricity will be transmitted to the metal frame, causing great harm to the drivers and passengers. Not only that, after the occurrence of leakage, there are also great problems for rescue workers. Cutting off the power supply in the car can make the emergency workers work faster. Bosch recently launched a set of electric vehicle anti electric shock system. When the vehicle collides, the internal device will automatically cut off the power supply to prevent leakage. Bosch designed and produced a cg912 chip, which was originally developed to trigger airbags. Now the cg912 is connected with a group of micro explosives. Once a collision is detected, the explosives attached to the battery pack will automatically send out a micro "explosion", so as to quickly cut off the connection between the power battery and the vehicle, make the battery fail, and avoid greater accidents. It should be noted that the "explosion" is safe and controllable, and will not cause harm to the driver and passengers. In addition to Bosch's cg912 chip, Autoliv recently launched a similar "high temperature safety switch". Although the technology is slightly different from Bosch's in design, its function is very similar. Both of them can automatically turn off the battery high-energy power circuit in traffic accidents, so as to prevent high-voltage electricity from flowing into the frame, further damage to the battery or fire.
