Special lithium-ion batteries have to be customized and have more requirements than ordinary lithium-ion batteries because they have to adapt to relatively harsh working conditions and temperature ranges. For 19 years, LARGE has focused on the customization of special lithium battery. According to the actual needs of customers, we can provide battery cell +BMS+ battery structure integrated lithium battery customization solutions and products.
Special lithium battery is roughly divided into four fields: low temperature lithium battery, explosion-proof lithium battery, high temperature lithium battery and high ratio lithium battery.
Special equipment, medical equipment, industrial equipment, polar research, exploration equipment, frigid zone rescue, deep sea diving, cold proof shoes and clothing, etc.
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
1.Shockproof: Fill the shockproof structure design through cold rolled sheet metal shell to achieve high safety and high reliability requirements;
2.High current: Use coppery nickel composite nickel belt to connect the cell, which is safe and reliable;
3.Communication interface: Use RS485 communication protocol, which can read battery voltage, current, temperature, capacity and other information;
4.Data communication management: Use BMS software management chip, accurate data transmission, precise temperature control to eliminate security risks;
5.The battery has temperature probe for safety. When the temperature exceeds, it will automatically protect the battery;
6.The battery pack has long battery cycle life, which is in line with low carbon, energy saving and environmental protection values;
7.Low temperature charge and discharge;
8.Lithium ion battery standard: in line with GB/T31467.3-2015 and CQC certification
