Charging circuit

Abstract

The invention provides a charging circuit. Charging operation on a battery is achieved through arranged digital signal sending module, a digital signal processing module, a stabilized voltage charging module and a charging polarization internal resistance eliminating module; a digital signal received from the digital signal sending module is processed through the digital signal processing module to control whether a circuit of the stabilized voltage charging module is conducted or not, so that the charging process of a rechargeable battery is controlled. The digital signal received from the digital signal sending module is processed through the digital signal processing module to control whether the circuit of the charging polarization internal resistance eliminating module is conducted or not, so that the charging polarization internal resistance is eliminated and heat and electrolyte crystal generated by the battery in the charging process are reduced. The charging circuit achieves elimination of the charging polarization internal resistance, reduces the heat and the electrolyte crystal generated in the charging process, improves the charge quantity of the rechargeable battery and prolongs the service lifetime.

Description

technical field [0001] The invention relates to the technical field of battery charging, in particular to a charging circuit and device. Background technique [0002] Currently, mobile electronic devices, small household appliances, electric vehicles, and diesel-electric submarines all require continuous power from rechargeable batteries to ensure normal operation. When the power of the rechargeable battery is exhausted, the rechargeable battery in the electric device needs to be charged, so as to continue to maintain the normal operation of the electric device. This requires a corresponding charging circuit to realize this charging function. [0003] In the related art, during the process of charging the rechargeable battery through the charging circuit, the rechargeable battery will generate charging polarization internal resistance, which is quite harmful because the resistance will generate heat, which will cause the temperature of the battery to rise. Due to the tight...

AI Technical Summary

Problems solved by technology

[0004] Charging under limited voltage conditions, the service life of the battery is also very limited. When the charging capacity exceeds the rated number of times, the charging capacity of the battery drops sharply. The generated heat catalyzes crystallization faster, and the charging capacity gradually decreases. Finally, the rechargeable battery is scrapped because the charging capacity cannot meet the electricity requirements, resulting in serious waste of resources and environmental pollution.
