Abstract

An auto-adapted track type power battery multi-stage high-speed charging system and the charging method, the characteristic is: includes the high-speed multi-switch high-power adapter subsystem, the four-stage charging controlling subsystem, and the auto-adapted track type controlling subsystem; the high-speed multi-switch high-power adapter subsystem uses to achieve high-efficiency high-power transformation and provides the corresponding working power to the system; the output end of the four-stage linearity charging controlling subsystem connects with the accumulator, feedbacks the sampling end of the auto-adapted track type controlling subsystem; the output end of the auto-adapted track type controlling subsystem connects with the adjusting end of the high-speed multi-switch high-power adapter subsystem. According to one of the flow, quick charge, over charge or float charge, achieves the corresponding charging switch along the change of the battery voltage automatically during the charging process.

Description

technical field

[0001] The invention belongs to power electronics manufacturing technology, in particular to an adaptive tracking type power battery multi-stage high-speed charging system and a charging method thereof. Background technique

[0002] At present, most domestic charging systems for power batteries are constant-voltage or current-limiting charging methods, or mixed constant-voltage and current-limiting charging methods. The constant voltage charging method has the disadvantages of long charging time, insufficient charging capacity, and excessive initial charging current of the deeply discharged battery, which is prone to damage to the battery or personal safety; although the charging time of the constant current charging method can be greatly shortened, the constant voltage charging Other disadvantages of the approach have not yet been overcome:

[0003] When charging a power battery in a deep discharge state (over-discharge state), the charging system should ha...
