Abstract

The invention provides a battery safety detection device, which measures battery units in a battery pack, wherein the battery pack comprises more than two battery units, and the more than two battery units are arranged at preset intervals. The invention further provides a battery management system.

Description

technical field [0001] The disclosure relates to a battery safety detection device and a battery management system. Background technique [0002] Lithium batteries are currently widely used in various aspects of industry and life, but there are some problems in the use of lithium batteries. For example, depending on the application environment of the battery, water vapor may be formed in the lithium battery pack. If the water vapor is too much , may cause damage to the lithium battery, for example, it may cause a short circuit of the lithium battery. In addition, lithium batteries will deform when subjected to external forces, and will also produce bulges after the battery ages. When the above problems occur in lithium batteries, problems such as internal short circuit, fire and explosion will occur. Therefore, the safety detection of lithium batteries is necessary. [0003] Usually, the moisture sensor in the lithium battery is detected by a humidity sensor, and the defo...
