Full automatic balance type battery pack charger device

Abstract

The invention discloses a full automatic balance type battery pack charger device which comprises an AC input unit, a series charging constant voltage and constant current charger, a central processing unit and a battery pack, wherein the AC input unit, the series charging constant voltage and constant current charger, the central processing unit and the battery pack are sequentially connected. The full automatic balance type battery pack charger device can overcome the defects of poor voltage balance, high cost, great difficulty in control of voltage compliance and the like in the prior art and realize the advantages of good voltage balance, low cost, small difficulty in the control of the voltage compliance and long service life.

Description

technical field The invention relates to a battery charger, in particular to a fully automatic balanced battery charger device. Background technique Generally, the battery pack charger adopts series charging or parallel charging, among which, the circuit structure of series charging is simple, high in efficiency, and low in cost; compared with series charging, the circuit structure of parallel charging is complex and low in efficiency. high cost. However, in the process of series charging, the voltage of a single battery in the battery pack cannot be monitored, which may easily cause a single battery to be overcharged or undercharged (that is, the voltage is unbalanced), resulting in a reduction in the capacity of the battery pack or damage to the battery pack. charge bad. In addition, in the process of charging and charging, the voltage of a single battery in the battery pack can be monitored; however, when the battery pack is composed of N batteries, the battery pack c...

AI Technical Summary

Problems solved by technology

(1) Poor voltage balance: When charging in series, it is impossible to monitor the voltage of a single battery in the battery pack, which may easily cause voltage imbalance, resulting in a decrease in the capacity of the battery pack or damage to the battery pack;

(2) High cost: In the process of charging and charging, when the battery pack is composed of N batteries, the battery pack charger needs to be composed of N completely independent chargers, resulting in a very high cost of the battery pack charger;

(3) It is difficult to control the voltage consistency: in the process of charging and charging, when the battery pack charger needs to be composed of completely independent N chargers, it is difficult to control the voltage of the N chargers consistently, and it cannot be effectively promoted
