The invention discloses an electric vehicle protection device based on safety performance optimization, and belongs to the technical field of electric vehicle control circuits. The technical problem of galloping danger of the electric vehicle is solved. According to the technical scheme, a power supply unit enables a microprocessor unit to work normally; the signal acquisition unit is provided with a signal line, the signal line is used for being connected with an electric vehicle speed regulation module and acquiring real-time speed regulation voltage, and the signal acquisition unit divides the speed regulation voltage and then inputs the voltage to the microprocessor unit; the microprocessor unit judges whether the real-time speed regulation voltage exceeds a fault threshold critical value or not, if yes, a power-off signal is sent, and if not, a virtual signal is output; the execution end of the circuit breaking execution unit is used for being connected with an electric vehicle power module, responding to a signal of the microprocessor unit, cutting off a power supply output line of the electric vehicle power module when receiving the power-off signal, and not executing actions when receiving the virtual signal.

    本发明公开一种基于安全性能优化的电动车的保护装置,属于电动车控制电路技术领域。为了解决电动车的“飞车”危险的技术问题;其技术方案要点是电源单元让微处理器单元正常工作;信号采集单元,具有信号线,信号线用于连接电动车调速模块并采集实时调速电压,信号采集单元将实施调速电压进行分压后输入给微处理器单元;微处理器单元,判断实时调速电压是否超过故障阈值临界值,如果超过,则发送断电信号,否则输出虚信号;断路执行单元,执行端用于连接电动车电源模块,响应微处理器单元的信号,接收到断电信号时,切断电动车电源模块的供电输出线路,接收到虚信号时,不执行动作,具有:工作安全可靠的效果。
