The invention provides an insulation acquisition circuit, a battery management system and a new energy automobile, in the insulation acquisition circuit, an operational amplifier is saved, the circuit structure complexity is reduced, the used operational amplifier is of a single power supply, the power supply system design scheme is optimized (a negative voltage power supply does not need to be designed), and the cost is greatly reduced. The use cost of one operational amplifier is reduced, and the device cost of the negative voltage power supply is also reduced.

    本发明提供了一种绝缘采集电路、电池管理系统和新能源汽车,该绝缘采集电路中,节省了一颗运算放大器,降低了电路结构复杂度,并且使用的运算放大器为单电源的,优化了电源系统设计方案(无需再设计负压电源),在成本上,既减少了一颗运算放大器的使用成本,又减少了负压电源的器件成本。
