Abstract

The invention provides a battery detection method, circuit and device. The circuit includes: a plurality of battery branches connected in parallel; the first end of each battery branch is electrically connected to the first node, and the second end of each battery branch is electrically connected to the first node. The two nodes are electrically connected, and each battery branch is provided with a battery to be tested, and one of the battery branches is recorded as a reference branch, and the leakage current of the battery to be tested in the reference branch is a known quantity; The current collector is used to directly or indirectly detect the current in each battery branch circuit, and provides a circuit basis for batch measurement of the battery to be tested.

Description

technical field [0001] The invention relates to the technical field of electronic circuits, in particular to a battery detection method, circuit and device. Background technique [0002] In the existing battery leakage detection scheme, the battery leakage is usually detected by using a symmetrical ring circuit topology and an internal short circuit identification method based on a symmetrical ring circuit topology. During the detection process, by comparing the characteristic values ​​of each battery, To determine that a certain battery is an internal short circuit battery. Wherein, the characteristic value of the battery here may be the correlation coefficient between the actual current value of each battery and the theoretical current value, or the measured current proportional relationship of each battery, etc. [0003] However, the above-mentioned battery testing scheme is usually used to test the batteries individually, and cannot perform batch testing on the batterie...
