Problems solved by technology

However, in a low-temperature environment, even if the battery pack has sufficient power, the need to discharge the heating pack will cause the battery pack to lose too much power and trigger the low-voltage protection of the battery pack, resulting in the false impression that the battery pack is insufficient. Unreasonable low-voltage protection prevents power supply to the heating components, which seriously affects the heating efficiency of the battery components, which in turn affects the starting of cars, etc., causing inconvenience to users

Abstract

The present application provides a heating device for starting a power supply and a battery pack thereof. The heating device comprises a heating assembly and a control unit. The heating assembly is arranged on the battery module and receives the discharge of the battery module to heat the battery module. When the temperature of the battery pack is lower than a preset temperature threshold, the control unit controls the battery pack to periodically discharge the heating assembly to avoid triggering low voltage protection of the battery pack during discharge of the battery pack to the heating assembly. The control unit controls the battery pack to periodically discharge the heating assembly to avoid triggering low voltage protection of the battery pack during discharge of the battery pack tothe heating assembly. The heating apparatus provided by the present application controls the battery pack to periodically discharge the heating assembly and the battery pack to periodically dischargethe heating assembly, The battery module can effectively prevent the discharge of the battery module to the heating assembly from triggering the low-voltage protection of the battery module, therebyensuring that the battery module can normally discharge the heating assembly in a low-temperature environment, and can improve the heating efficiency of the battery module, so that the battery modulecan quickly recover the function of normal external discharge.

Description

technical field [0001] The application relates to the technical field of circuit control, in particular to a starting power supply and a heating device for battery components thereof. Background technique [0002] Motorized devices (such as automobiles, helicopters, etc.) use starter power to provide power for starting the engine. In a low temperature environment, especially in the colder north, the battery components used to start the power supply cannot provide instantaneous high current due to their low temperature, resulting in the inability to start motorized devices such as cars. Therefore, before starting motorized devices such as cars, it is necessary to The battery pack that starts the power supply is heated. During the low-temperature heating process of the battery assembly, the battery assembly supplies power to the heating assembly, and then the heating assembly converts electrical energy into heat energy to heat the battery assembly. However, in a low-temperat...
