The invention relates to the technical field of vehicle-mounted starting batteries, in particular to a vehicle-mounted starting battery capable of keeping emergency starting of a vehicle in a wireless mode. The battery realizes monitoring and protection of information such as voltage, current and battery cell temperature through a battery management system (BMS), and receives an instruction from a user mobile phone through a wireless Bluetooth communication module so as to control the discharge state of the battery. The battery management system (BMS) comprises a cell acquisition port, a battery equalization circuit, an MOS drive circuit, an acquisition chip (AFE), a temperature sensor (NTC) acquisition port, a microprocessor unit (MCU), a communication interface (UART/485/CAN), a parameter/protection information storage unit (ROM), a function key reserved port, a power conversion circuit, a power device (MOSFET) and a precision high-power resistor (shunt). According to the invention, real-time monitoring and protection of key parameters such as battery voltage, current and battery cell temperature are realized through a built-in battery management system (BMS).
