Disclosed is disconnection of a vehicle electric system using a low voltage switch. A power system (100, 200) for a vehicle, the power system comprising: a hazardous voltage interlock loop (HVIL) circuit (106) configured to disconnect a high-voltage energy source (102) from a high-voltage system (104); a low-voltage energy source (108) coupled to the HVIL-circuit for supplying operational power to the HVIL-circuit; and a circuit breaker (110) operable to break a connection between the low-voltage energy source and the HVIL circuit, wherein the HVIL-circuit is configured to disconnect the high-voltage energy source from the high-voltage system if the low-voltage energy source is disconnected from the HVIL-circuit.
本发明涉及使用低压开关的车辆电气系统的断开。一种用于车辆的电力系统(100、200),包括:危险电压互锁回路(HVIL)电路(106),其被配置成将高压能量源(102)与高压系统(104)断开;低压能量源(108),其耦合到HVIL电路,用于为HVIL电路提供操作电力;和断路器(110),其可操作以断开低压能量源和HVIL电路之间的连接,其中,HVIL电路被配置成如果低压能量源与HVIL电路断开,则将高压能量源与高压系统断开。
