Abstract

The invention relates to an equalizing charging device which consists of an upper computer, a charge equalizing device and a matched signal input/output (I/O) port, wherein the charge equalizing device is connected with a rechargeable battery pack by the matched signal I/O port; the upper computer comprises a charge control device; the charge control device is used for receiving change data of current and voltage of all rechargeable batteries in the rechargeable battery pack, forming corresponding control parameters, and sending the parameters into the charge equalizing device by a serial communication bus for controlling states of the charging processes of all the rechargeable batteries, wherein the change data are acquired by the charge equalizing device through the serial communication bus; and the charge equalizing device comprises an intelligent equalizing module which is used for adjusting the working state of the corresponding signal I/O port by the control parameters of the charge control device. The equalizing charging device can be used for performing independent charge control on all the rechargeable batteries, so that the rechargeable batteries in the rechargeable battery pack can be charged in a balancing way. Energy of the rechargeable battery pack is exerted to the greatest extent, and the service life of the battery pack is prolonged. The invention also comprises a corresponding charge control method.

Description

technical field [0001] The invention relates to a charging device, in particular to a charging device for series energy storage devices. Background technique [0002] At present, in the batch manufacturing process of lithium-ion batteries, due to the performance of the manufacturing equipment, the consistency of raw materials, and the control accuracy of temperature and humidity in the manufacturing process, the finished lithium-ion batteries will suffer from poor , diaphragm thickness and other index parameters are different. This will inevitably lead to differences in capacity and internal resistance of mass-produced lithium-ion batteries. When lithium-ion batteries are connected in series and parallel to form the power supply of electric vehicles or other electrical equipment, during the charging and discharging process, the energy loss of each battery will be different. The charging capacity of different batteries is inconsistent, and the inconsistent charging capacity...
