Abstract

The invention discloses an equalizing charge method and an equalizing charger. The equalizing charge method comprises the following steps: (1) connecting N (N is integer and is more than or equal to 2) single batteries in a battery pack in parallel; (2) independently and quickly charging the N single batteries at the same time; and (3) after the single batteries meet the charge requirement, finishing charging the battery pack. The equalizing charge method of the invention changes the series discharge mode of the single batteries of the battery pack into a parallel mode to independently charge the batteries of the battery pack, thus independently controlling the charge process of the single batteries to ensure equalizing charge for the single batteries. The charger of the invention uses a single chip control center as the core, and simply and precisely realizes independent charge and independent control of the single batteries.

Description

technical field

[0001] The invention relates to a method for charging a battery and a charger, in particular to a method for equalizing charging of a lead-acid battery and an equalizing charger using the method. Background technique

[0002] The battery is the main energy storage element of various electric devices such as electric vehicles, and is a relatively critical component. The performance of the battery will directly affect the performance of the electric vehicle.

[0003] The commonly used rechargeable battery pack is composed of multiple rechargeable batteries connected in series, so a single battery is the basic unit of the battery pack. From the use of electric vehicles, it is found that the service life of battery packs in electric vehicles is much shorter than the normal service life of a single battery. Research shows that this is because the batteries are in an unbalanced state.

[0004] Among the single batteries that make up the series battery pack, due to...
