The invention discloses a device for increasing the endurance mileage of a battery pack and a control system of the device, and relates to the technical field of lithium batteries, the device and the control system of the device comprise a voltage protector, a power supply module, an MOS tube isolation driving module, a power converter, a synchronous rectification output module, an output device and the like, a high-voltage protector is arranged in the voltage protector, and a low-voltage protector is fixedly installed in the position, located on one side of the high-voltage protector, of the voltage protector. According to the device for increasing the endurance mileage of the battery pack and the control system of the device, a voltage sampling module is composed of an R69, an RW3, an R71, an R72, an R70 and a C54, a voltage signal is input into a P I regulator to adjust the PWM width so as to adjust the voltage, a current sampling module is composed of a U11 and a U9A, a signal sampled by a U11 Hall sensor is output to the U9A through an RW2 to carry out PI adjustment so as to adjust the PWM width so as to adjust the output current, and the output current of the battery pack is adjusted. And when the sampling voltage of the U9B is lower than the set voltage, the output short-circuit protection enters a protection state.
