Abstract

The invention discloses a charging apparatus capable of performing single-battery charging and serial discharging for a battery pack, and relates to the technical field of charging of the battery pack. By virtue of the charging apparatus, charging of other single batteries is not affected by damage of a certain single battery. The charging apparatus comprises a microcontroller and a battery connecting module, and chargers, selector switches and current-limiting modules with the same number as the single batteries; the battery connecting module comprises body charging connecting mechanisms with the same number as the single batteries; the power supply output end of each charger is connected with one wiring end of the selecting end of the corresponding selector switch in a one-to-one correspondence manner; the rotational end of each selector switch is connected with one end of the corresponding current-limiting module in a one-to-one correspondence manner; the other end of each current-limiting module is connected with the corresponding body charging connecting mechanism of the battery connecting module in a one-to-one correspondence manner; and the battery connecting module is connected with the battery pack.

Description

technical field [0001] The invention relates to the technical field of battery charging, in particular to a charging device capable of charging and discharging battery cells in series. Background technique [0002] At present, charging devices all use a charger to charge the battery pack, and the single cells in the battery pack are connected in series with each other during the charging process. As long as one single battery fails among the single batteries connected in series, the whole battery pack will not be charged well. Therefore, it is very necessary to design a charging device in which the damage of a single battery will not affect the charging of other battery cells. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned deficiencies existing in the existing charging device, and provide a charging device capable of charging and discharging the cells of the battery pack in series. The charging device can prevent t...
