If the drive system and control system of electric bicycles have been designed, it has a good indicator system, and the battery manufacturer can begin the most important energy storage component – batteries.
The electric bicycle battery has advantages such as its unique less maintenance, maintenance and discharging performance, so that the market has accepted repeatedly, but the actual use of the market is much different from the performance parameters specified in JBFRRO262 One 2001 standard. Bike battery industry standard requirements produced by battery manufacturers (Take 6 DZM 10):
12 hour rate capacity: 10ah (discharging at the SA current to 1.6VL monomer is not less than 120 min.
2 Palectural retention characteristics: 28 days, the remaining capacity is not less than 8.5ah.
3 large current discharge characteristics: 5min at 15A current discharge, the end voltage should not be less than the L.4VL single.
4 Over-discharge characteristics: Under the conditions of the impedance, the current of (12 +/- 1.2) A is continuously discharged from 2LH, and the capacity should not be less than 7.5ah.
5-10 ° C low temperature capacity: ROH in an environment in one (RO earth L) ° C, the actual capacity should not be less than 7ah. After the electricity is 29h, the gas composite efficiency should not be less than 90%.
6 Circulating life: 70% depth discharge, cycle life is greater than 350 times, life is a very important parameter, and it is not possible to produce the battery manufacturer.
