Produce & Test
Produce:
HOW IS QUALITY & PRODUCTION GUARANTEED ? Check out our advanced production facilities and testing facilities .
Polinovel provide both battery cells and battery packs, with the most advance production technology and the highest quality components, to make our lithium batteries unlike Others in the market. Polinovel strictly follow the high-standard production and testing processes, to guarantee lithium batteries are qualified and safe for use in different applications.
Test:
Analog Car Vibration Test of Lithium Battery
Analog the damage caused by bumps in the transportation process, to make sure the resistance of lithium battery for environmental vibrations.
Analog Lithium Battery encountered different road conditions such as bumps, uphills, downhills, turns, sharp turn, etc. Polinovel Lithium Battery is suited to all the above road conditions, not only with stable performance, but also safe and secure.
Waterproof test on lithium battery
Put the batteries in the sink, fill with water and put some fish in.
Multimeter measuring battery voltage and current, battery work normally, and fish is alive, No electric leakage. Polinovel high technology including special processing on lithium battery production crafts to meet the requirements of IP standard in different installation and operating environment. If you want waterproof lithium battery, we are very pleasure to provide you, please let us know your requirements.
Nail Penetration Test
To approve the safety of our LiFePO4 Batteries, we had a series of environmental tests.The battery pack is penetrated by two nails, after 6 minutes, there is no fire, no explosion during the whole testing process.The stable chemistry of lifepo4 battery proofs to be outstanding safe for use even in extremely tough operating environment.
Temperature Effects on LiFePo4
Most of our customers concerns about the working temperature of our batteries, sometimes, even we know that the common working temperature of different chemistry lithium batteries, they still hope to confirm with the supplier before making an order. Below testing results is about the discharge capacity of 12V 100Ah LiFePo4 battery pack under different temperature.
@1C discharge, our battery remains, 75% discharge @working temperature -10℃; 90% discharge @working temperature 0℃; 98% discharge @working temperture 20℃; 99% discharge @working temperature 40℃
Over-temperature Protection
With over temperature protection, BMS will cut off discharge or charge when battery temperature meet 65℃.
