A battery charge and discharge control system with active heat dissipation

Abstract

An actively radiating battery pack charging / discharging control system provided by the present invention comprises a microcontroller, a signal acquisition device, a charging / discharging control circuit and a synthetic jet drive circuit, and the signal acquisition device comprises a voltage collector and a current collector of a battery pack, a stabilization sensor arranged inside a battery box body and a voltage sampling circuit connected with a synthetic jet device. The output end of the signal acquisition device is connected with the input end of the microcontroller via an A / D converter, and the output end of the microcontroller is connected with the charging / discharging control circuit and the synthetic jet drive circuit. The synthetic jet drive circuit comprises a drive circuit connected with the output end of the microcontroller, an inverter circuit connected with the battery pack and a filter circuit connected with the output end of the inverter circuit, and the output end of the filter circuit is connected with the synthetic jet device. According to the present invention, the synthetic jet device radiates the heat in the interior of a battery box actively, thereby improving a heat radiation effect, and prolonging the service life of a battery.

Description

Technical field [0001] The invention relates to a battery control system, in particular to a battery pack charging and discharging control system with active heat dissipation. Background technique [0002] The battery box is a device that can accommodate one or more batteries. It can assemble multiple batteries together to improve the power supply capacity. When the battery is charged or discharged, some heat will be generated. When the battery is charged or discharged for a long time, a large amount of Heat, if the inside of the battery box is not radiated in time, it will cause huge damage to the battery. In severe cases, fire or explosion accidents may occur, resulting in huge losses of personnel and property. Summary of the invention [0003] In view of the above-mentioned technical problems, the present invention proposes a battery pack charging and discharging control system with active heat dissipation. [0004] The technical solution of the present invention is: a battery p...

Problems solved by technology

[0002] A battery box is a device that can accommodate one or more batteries. It can assemble multiple batteries together to improve power supply capacity. When the battery is charging or discharging, it will generate some heat. When charging or discharging for a long time, it will accumulate a lot of heat. Heat, if the internal heat dissipation of the battery box is not timely, it will cause huge damage to the battery, and in severe cases, accidents such as fire or explosion may occur, resulting in huge losses of personnel and property
