Explosion-proof battery is a new type of battery product, which is made of high safety material and can effectively prevent the explosion of the battery.
The safety performance of explosion-proof battery is its distinguishing feature.
Explosion-proof lithium battery will have different explosion-proof requirements due to the actual use of the environment, such as Exia explosion-proof lithium battery mainly refers to the mine lithium battery, others are high temperature explosion-proof, explosion-proof puncture and explosion-proof collision, etc.
1.Product design reference GB3836 / Exib iiB T4
2.Passed the National Coal Safety certification, and can be used in mines and oil wells.
3.0.5C for 400 times, capacity retention rate ≥80%
4.Can be used in zone I, ZONE II explosive gas dangerous places.
5.It has built-in charge and discharge protection circuit board, which can avoid overcharge or overdischarge damage to the battery;
6.Multiple protection: short circuit protection, over charge protection, over discharge protection, temperature protection.
Oil and gas drilling, mine locomotive, petrochemical industry, refuge chamber, fire helmet mask and other explosion-proof places
Battery Cell Selection + PCM & BMS + Structure Design + Chargers
Cell Selection and Cell Quality Detection
Design of shape and internal structure
Electrical performance design：protection function, accurate power display, host communication, certification, battery set-making, charging
Charger design：External or built-in charger
Mid-term overall re-evaluation
Basic electrical performance test, and test under different environmental conditions
The safety performance of explosion-proof battery is its distinguishing feature, and it has the following characteristics:
1.Explosion-proof lithium battery is designed to meet the IIB gas group below, combustible dust and other special environment;
2.Its manufacturing complies with GB3836-2010;
3.Using scientific explosion proof structure to meet the requirements of IIB;
4.Using Japan/South Korea high quality A quality cell, which is stable and reliable;
5.It has longer cycle life, small capacity consumption and high volume utilization;
6.A protective device is installed to prevent the battery from overheating and damage;
7.Prevent polarity inversion or reverse charging by another battery in the same battery pack;
8.Special explosion-proof line: When the internal pressure reaches a certain value, the battery will automatically release vent valve. Anti-high temperature, anti-high pressure, anti-air leakage performance is beyond the standard.
9.During the design of lithium-ion battery system, it is necessary to provide two electronic protection for overcharge, overdischarge and overcurrent respectively, among which the protective board is the second one. After the protective board is removed, the battery should not fail.
