Abstract:The influencefactors of assemblingpressure,carbon material,sodium lignosulfonate and container formation temperature on the capacity of lead-acid battery for E-bikes at low temperature were mainly examined in this paper. The experiments results showed that the assembly pressure affected the capacity at low temperature. The carbon materials with high specific surface area could significantly reduce the capacity at low temperature and accelerate the water loss.If the temperature was higher than 45'C, it would bring in adverse effects on the capacity at low temperature. Moreover, if the amount of sodium lignosulfonate was reduced, the low temperature capacity would be significantly reduced, especially in the case of higher formation temperature.
Key words: E-bike, power battery; capacity at low temperature; assembling pressure; specific surface area; sodium lignosulfonate; carbon material; formation
