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, custom battery, then 0.05C10A charging when the voltage reaches 2.40V, intermittent 30min, then halve the charge current to voltage and electrolyte density remained stable, stop 20min , then 0.05C10A charge, and so forth until the battery reaches normal state.

The main types of lead-acid batteries and automotive batteries purposes: for automotive starter, 12v battery custom, lighting, ignition, etc., which require large current discharge, low temperature performance characteristics. Fixed Battery: Widely used in electric power, telecommunications, power plants, nuclear power plants, hospitals, halls, etc., as a backup power source. Railway Passenger Car Battery: mainly used for train lighting, ventilation and other standby power. Traction batteries: mainly used battery car, truck, mine locomotive power, require deep charge-discharge performance, so use tubular positive plate of the battery. Locomotive Battery: mainly used for diesel locomotive starting, lighting, etc., requires a large current discharge performance, custom toy car battery, so use paste type electrode plate. Motorcycle batteries: mainly used for motorcycle starter, ignition, lighting, 16v batteries customized, require large current discharge performance is good. Bicycle Battery: mainly used in electric bicycles, electric tricycles, electric scooters and other power supply. Above content provided by Hebei Tianyi Electric Co., Ltd., we hope to help a friend in the same industry. 16v battery customized, create resistant cells, batteries customized by Hebei Tianyi Electric Co.
