随着电动和混合动力系统在客车和公共交通中越来越受欢迎,需要采取其他措施来确保驾驶员和乘客的安全。在HV电池使用量持续增长的条件下,必须有自动系统来处理特定的紧急情况,例如:电池爆炸或设备损坏引起的火灾。  即使在仅造成中度损坏的碰撞事故中,也存在电流从HV电池泄漏到金属底盘或车架中的风险,使车内人员、救援人员和急救人员暴露于致命的电击之下。 阅读更多

Pyroswitches based solutions

Pyroswitches based solutions

ST’s dedicated passive safety solutions based on pyroswitches can activate specific countermeasures such as battery disconnects or fire extinguishers to remove or reduce the risks related to crash events involving HEV/PHEV and BEV. Our pyrotechnical safety switch system triggers controlled micro-explosions, cutting the wiring between the high-voltage battery unit and the rest of the vehicle, thus reducing or eliminating the flow of current and risk of electric shock or fire. 

Flame, smoke and thermal sensors in addition to accelerometers can communicate with the vehicle’s airbag system, battery management system or vehicle control unit to activate the proper countermeasure. 

ST’s passive safety products serve the global automotive market with several millions of parts produced annually. Our airbag systems and deployment drivers are well established robust products with many years of proven experience in the field.
