Lead-acid battery electric car charging balanced approach called intermittent charging method. Intermittent charging method: When the battery is fully charged Normal (with fully charged flag), intermittent 60 minutes, 120 minutes and then charged with 0.03C10A current, so repeated 3-4 times until a power can immediately read the last measured voltage values, but the density of the electrolyte within 3 hours longer increases. Before the end of equalizing charge, electronic battery prices, the electrolyte density adjusted to 1.24 ± 0.01g / cm3 (20 ℃), the liquid level to the maximum level line.

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 relatively serious, electronic battery 3v, may be 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, electronics batteries, intermittent 30min, electronics battery Which is good, then the current reduction charge to voltage and electrolytic liquid density remained stable, stop 20min, then 0.05C10A charge, and so forth until the battery reaches normal state.
