Electric car battery sulfation main characteristics:. A plate sulfate electrolyte density will decrease. b. When the charging voltage rises rapidly, discharge voltage drop fast. c. plate surface color is not normal, small white particles. (Lead sulfate crystals) d. Low battery capacity. Remedy sulfation relatively minor, the charge can be balanced treatment. Sulfation more serious, you can use a small current overcharging law. That first electrolyte density adjusted to 1.208 / cm3 or less, then 0.05C10A charging when the voltage reaches 2.40V, 12V1.3AH electronic scale battery, intermittent 30min, then halve the charge current to voltage and electrolyte density is not stable change, stop 20min, then 0.05C10A charge, and so forth until the battery reaches normal state.

Reduction of lead-acid batteries vulcanized "recipe" to reduce the battery sulfide, extend battery life, we must first improve the bike working environment. Reduce body weight, all kinds of electronic scales battery, remove unnecessary garnish, appropriate speed, not carrying a heavy load for a long time without the use of electric bikes do supplementary charge, the best is able to charge after each discharge, do undervoltage protection to prevent battery discharge, for a nominal voltage of 24V protection should be set at 21.5V ~ 22V, 36V nominal voltage protection for should choose 32.5V ± 0.5V, should be provided for a nominal 48V In 44V ~ 45V. Such continued line voltage capability is only reduced by less than 2 km, but can effectively extend battery life. Every three months on a regular basis to professional service points overhaul battery, timely replenishment. The method is simple, electronic scale battery, the economic cost is very low, but there is a certain degree of difficulty to strictly abide by. So, you can use specialized equipment for sulfur removal for maintenance. Above content provided by Hebei Tianyi Electric Co., Ltd., we hope to help a friend in the same industry.
