Abstract

The invention relates to a battery balancing control method and device and a balance control system, and belongs to the technical field of battery balancing. The method comprises that whether an intelligent battery is in a charging mode is determined; if YES, a control chip in the intelligent battery obtains state information of an electric core group in the intelligent battery, and whether the intelligent battery satisfies a balancing condition is determined according to the state information of the electric core group; and if YES, the battery balancing control device balances the intelligentbattery. The battery space and weight are reduced, and the voltage balancing precision of the electric core of the battery is improved.

Description

【Technical field】 [0001] The present invention relates to the technical field of battery balancing, in particular to a battery balancing control method, device and battery balancing control system. 【Background technique】 [0002] At present, the consistency of batteries is one of the biggest obstacles restricting the application of multi-string lithium batteries. Inconsistent batteries will deteriorate with the increase of the number of cycles, and even lead to safety accidents in severe cases. During production, the batteries are usually matched consistently. However, due to temperature differences and other reasons during use, the consistency of the batteries will become worse and worse. [0003] In order to avoid the deterioration of battery consistency, a commonly used solution is to design an equalization circuit inside the battery, and through the equalization circuit to control each battery cell to be equalized to the same level when it is inconsistent; another soluti...
