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 division branches. The battery pack is composed of N battery modules which are arranged in series, wherein N is greater than or equal to 2. The negative electrode end of a first battery module is the negative electrode end of the battery pack, and the positive electrode end of an Nth battery module is the positive electrode end of the battery pack. The negative electrode end of the first battery module, the connection point of any two adjacent battery modules and the positive electrode end of the last battery module are each connected with one end of one voltage division branch, and the other ends of all the voltage divisionbranches are connected. Each voltage division branch is provided with an input control switch and at least one voltage division resistor in series, each voltage division branch is provided with a voltage acquisition point used for being connected with a voltage acquisition module in an output mode, and the voltage is adjusted by inputting different voltage division branches. The voltage regulationrange is large, the cost is low, and the acquisition precision of the voltage acquisition module in the full range can be tested.

Description

technical field [0001] The invention relates to a battery pack voltage regulating device and a voltage regulating 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 a 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 is not adjustable, it is not possible to test the acquisition accuracy of the battery voltage acquisition module within the full range. 2. Connect the battery voltage acquisition module to the battery simulator. The battery simulator uses an electronic adjustment device to simulate a real battery. The voltage can be adjusted and the voltage adjustment range is wide. However, the structure of...
