Conventional temperature detection When the battery is heating, although IC can be informed of the main circuit, it cannot prevent the continuous discharge inside the parallel battery module, and because the main circuit is cut off, all the energy of the battery module is concentrated in the inner short -circuit battery, but increases increase The heat out of control occurs.
The ideal scheme is that when the battery occurs in the short and warmed up, the connection loop between the battery and other batteries in the module can be cut off. It is shown that the TE PPTC or MHP-TA series products are assembled on the single-section battery. When the inner short circuit occurs, the TE protective device can effectively block the connection between the inner short-circuit battery and other batteries in the module to prevent the occurrence of malignant accidents. For the large number of power battery packs with a large number of single batteries, the consistency of the internal resistance of the battery and the device is high during configuration. Due to its internal dual metal structure, the consistency of the device resistance is very good, which can greatly satisfy the for. Requirements for battery internal resistance
Regarding the assessment indicators of lithium ion battery safety performance, it stipulates very strict standards internationally. A qualified lithium ion battery should meet the following conditions in terms of safety performance:
(1) Short circuit: no fire, no explosion
(2) Over charging: no fire, no explosion
(3) Hot box test: no fire, no explosion (150 ℃ constant temperature 10min)
(4) Needle: Do not explode (penetrate the battery with ф3mm nail)
(5) Tablet impact: no fire, no explosion (10kg heavy objects smashed from 1M high to the battery)
(6) Burning: Do not explode (gas flame barbecue battery)
