Battery Pack Balance Restoration Management System

Abstract

The invention discloses a battery pack balancing repair management system comprising a collecting circuit, a processing circuit and a balancing repair circuit. The collecting circuit is used for collecting the electric quantity of each battery of a battery pack after an emergency start power supply successfully starts a vehicle, and transmits the electric quantity to the processing circuit; the processing circuit is used to determine whether a difference between a maximum value of the electric quantity and a minimum value of the electric quantity is greater than a safety set value, and starts the balancing repair circuit to repair the battery pack if yes, or stops the balancing repair circuit if not. The battery pack balancing repair management system detects the counter-charge situation of the battery pack in real time, performs balancing repair on the imbalanced battery pack, minimizes the imbalance of the battery pack, makes every battery of the battery pack at the most balance state constantly, enables the battery pack to operate evenly before a user uses the battery pack next time no matter the battery pack is charged or discharged, and prolongs the service life of the battery pack.

Description

technical field [0001] The invention relates to an emergency starting power supply, in particular to a balance restoration management system for a battery pack in the emergency starting power supply. Background technique [0002] Although the general emergency starting power supply is equipped with conventional charging shutdown, charging balance and other technologies, in practical applications, the biggest damage to the charging of the battery pack in the emergency starting power supply is not from the normal configuration of the charger charging control system, but in the After the car is successfully started, the reverse charging of the super-high-power generator charging system of the car causes the battery pack to be unbalanced. This kind of high-power reverse charging cannot achieve balance control. If the battery pack is already in an unbalanced state, it will be idle or continue to start. When used, the already unbalanced battery pack will accelerate the vicious cyc...

This kind of high-power reverse charging cannot achieve balance control. If the battery pack is already in an unbalanced state, it will be idle or continue to start. When used, the already unbalanced battery pack will accelerate the vicious cycle, eventually leading to premature failure and damage of the battery pack
