一款纯电动汽车碰撞断电功能及碰撞后高压电安全测试

After-crash Power Off Function and High Voltage Security Test for an EV City Bus

设计一款纯电动汽车整车碰撞断电方案,并介绍整车碰撞过程中的碰撞断电功能的测试验证方案。通过碰撞断电功能,确保电动汽车在碰撞发生过程中及时切断整车高压电,确保整车高压电安全。测量方案可以验证碰撞断电功能的执行情况,并可以测量碰撞后的正常高压安全情况,为电动汽车的高压电碰撞安全提供工程方案和验证方案。

The author designs a solution for pure electric vehiele power off when crashing and intriduces verification test scheme. Through this solution of power off, the electric ear in erash could cut off the high voltage power in time, lo ensure the high vohage security of the vehicle. The measurement scheme can verify the performance of this power off function, and can confirm the high voltage safety after the vehicle crash, which provide engineering and verifying strategy for pure electric vehicle seeufity after crash.
