Abstract

The invention relates to a battery pack voltage regulation device and a voltage regulation control method thereof. The device comprises a battery pack and N+1 voltage dividing branches. The battery pack is composed of N battery modules arranged in series, N≥2, and the first The negative terminal of one battery module is the negative terminal of the battery pack, the positive terminal of the Nth battery module is the positive terminal of the battery pack, the negative terminal of the first battery module, the connection point of any two adjacent battery modules and the last The positive terminal of a battery module is correspondingly connected to one end of a voltage divider branch, and the other ends of all voltage divider branches are connected to each other. Each voltage divider branch is provided with an input control switch and at least one voltage divider resistor in series. Voltage collecting points for output connection to the voltage collecting module are set on the voltage dividing branches, and the voltage is adjusted by inputting different voltage dividing branches. The voltage adjustment range of the present invention is large, and the cost is low, and the voltage acquisition module can be tested with the acquisition accuracy within the full range.

Description

technical field [0001] The invention relates to a battery pack voltage regulation device and a voltage regulation control method thereof, belonging to the technical field of battery management. Background technique [0002] The battery signal acquisition module or the battery voltage acquisition module needs to be connected to the battery for voltage acquisition test during the production process to determine whether the acquisition accuracy is normal. There are two common methods at present: 1. Connect the battery voltage acquisition module to a real battery. Since the battery voltage cannot be adjusted, the acquisition accuracy of the battery voltage acquisition module in the full range cannot be tested. 2. Connect the battery voltage acquisition module to the battery simulator. The battery simulator uses an electronic regulating device to simulate a real battery, the voltage can be adjusted, and the voltage regulation range is wide, but the structure of the battery simula...
