The invention belongs to the field of starting power supplies, and discloses an automobile starting power supply battery management system and an automobile starting power supply, and the automobile starting power supply battery management system comprises a super capacitor, a heating film, a charging and discharging MOS, a sampling resistor, a temperature acquisition circuit, a voltage acquisition circuit, a current acquisition circuit, an analog front-end chip and a microcontroller unit; a charging and discharging management module, a heating film management module and a short circuit protection module are arranged in the microcontroller unit. The super capacitor is integrated to serve as auxiliary energy, the reliability and emergency capacity of automobile starting are effectively improved, thousands of amperes of current can be instantaneously output based on the design of the super capacitor, and the defects that a conventional lithium battery protection plate is prone to triggering short circuit protection by mistake and a battery cannot instantaneously output full-load current are overcome. And meanwhile, the heating film management module is used for performing temperature management on the starting power supply, so that the problem that the battery performance is reduced in a low-temperature environment is effectively solved. In addition, the built-in short circuit protection module and the built-in charging and discharging management module provide comprehensive safety guarantee for the system.
