When electric lithium battery assembly must pay attention to what problem

Matters needing attention in using of batteries, including batteries, screening, top of aluminum-plastic composite membrane, sealing side, A shaft end sealing side) , side sealing side, extremely handle protection and measures to avoid mechanical impact, short circuit. After gaining 1 screening, batteries, batteries, how to distinguish good or bad. Must use internal resistance tester, capacity tester. How much is the test nominal MH, what is the actual MH. If the nominal parameter difference, the greater the representative quality worse. The lower the battery internal resistance, the better. Batteries is a pit, will check the test equipment, no equipment is to buy lottery tickets, lu: su composite film packaging protection: the main is to avoid from damage by the sharp parts stabbed. Therefore, we should always clean up battery surroundings, banning sharp collision parts contact or batteries, can put on the gloves when use, avoid fingernails scratch the surface of the batteries. 3, top sealing side and side sealing side protection: to avoid the top sealing side and side sealing side damage, damage to the sealing effect, should be prohibited from bending top sealing side and side sealing side; At the same time, the batteries to design the insulation of the reliable isolation measures must be taken to avoid the negative and aluminum-plastic composite membrane docking short circuit. 4, handle protection: lithium polymer batteries batteries positive leading-out terminal aluminum handle, the cathode leading-out terminal using nickel handle. Due to the extremely thin, should be prohibited from bending; At the same time, in the process of production should be avoid extremely handle contact with lu: su composite membrane, with strict isolation ring membrane. More than 5, insulation protection: in the assembly monomer batteries in order to prevent the battery polarity when short circuit in series, insulation treatment, be in with PC film or with silica gel battery pole ear position interval is then wrapped in layers of insulation tape to fix, then add a layer of insulation at the position of the welding wire, add stripe rubber should be fixed. 6, avoid mechanical impact, such as fall, hit, bending batteries and carelessly trampled the battery. 7, it is prohibited to use metal, wire short circuit connected is negative. 8, waterproof protection: lithium battery, monolithic insulated before packing. Or choose waterproof battery pack. 9, battery demand shock! Electric cars in use, can't be suv! Nor use battery pack skins to realize buffer collision, the deformation will cause a short circuit! As far as possible with grid support + cushion + carton this way. Do not add grille support, battery pack in the years of pressure will cause a nickel chipped! 10, completes the heat dissipation, thermal conductive silicone pads do medium, to conduct the heat to the stainless steel shell. Or battery pack conditional offer heat conduction channel, energy conversion, the heat conduction in time can achieve the optimization of the battery. Steel box + auxiliary fan, are conventional solution. 11 and corrosion problem, the battery for long the rust, conditional as far as possible measures to prevent corrosion.
