Abstract

The invention discloses a battery thermal failure test system, which comprises a test chamber, a heating unit, a sampling unit and a control unit, the test cabin is a closed cabin body, a cabin cover is detachably and hermetically connected to the test cabin, and an air pressure detection device and at least one temperature detection device are arranged in the test cabin; the heating unit comprises a heating table arranged in the test chamber and an electric heating film laid on the top surface of the heating table, and the electric heating film is electrically connected with a power supply arranged outside the test chamber; the sampling unit comprises a gas power element, a pressure flow regulator, a dryer, a filter and a gas sampling device which are sequentially communicated through pipelines, and the gas power element is also communicated with the interior of the test chamber through a pipeline; the air pressure detection device, the temperature detection device, the gas power element and the pressure flow regulator are respectively in communication connection with the control unit, and the electric heating film is electrically connected with the temperature control meter. The battery thermal failure test system can test the thermal failure of the battery.

Description

technical field [0001] The invention relates to the technical field of battery testing, in particular to a battery thermal failure testing system. Background technique [0002] Safety is the lifeblood of energy storage. With the occurrence of thermal failure of new energy vehicles, more stringent requirements for personal safety have been put forward. For this reason, the Ministry of Industry and Information Technology has issued relevant standards for new energy buses, requiring new energy buses above 6m to be equipped with battery protection devices. In order to achieve the purpose of early warning and limited guarantee of the life safety of passengers. So how does thermal failure achieve this? Next let's see how it works. Taking lithium cobalt oxide as the research object, when a certain high temperature is reached, the positive electrode will decompose instantaneously and release oxygen, and the oxidation reaction of oxygen and solvent will generate a large amount of ...
