Technical Field

[0001] The utility model relates to new energy vehicle battery detection, in particular to a new energy vehicle battery discharge temperature testing device. Background Art

[0002] The production of new energy vehicles is gradually increasing. The core power inside them is provided by batteries. As core components, new energy vehicle batteries need to undergo strict testing before leaving the factory. One of the test indicators is the temperature of the battery during continuous discharge. Excessively high temperature indicates that there are quality problems with the battery and it needs to be returned to the factory for inspection and repair. Otherwise, there will be major safety hazards.

[0003] Current testing methods for new energy vehicle batteries essentially use a discharge tester in conjunction with an infrared temperature sensor. However, during actual installation and operation, batteries are generally not directly exposed to open space but are typically located in a closed space or one with certain ventilation gaps. Existing testing methods lack the design to simulate such conditions, and the test results lack rigor.

[0004] In order to solve the above problems, we have made improvements and proposed a new energy vehicle battery discharge temperature testing equipment. Utility Model Content
