Electric car battery problem Rollup 1, the imbalance. Capacity and voltage caused by differences. Is often a serious backward. Fix: change, but do not use a new one. 2, dehydration. Overcharge cause. Imbalance, charger reasons. Repair method: water (distilled water). 3, vulcanization. Due to charge cause. Dehydration, charger reasons. Repair Methods: 0.01-0.02C small pulse current. Electric car battery maintenance 7, battery discharge not a long lock, do not be turned off immediately. To the termination voltage resistance greater electrolyte concentration is very thin, especially the plate hole and surface almost in neutral, over-discharge resistance tend to have fever, volume expansion large electric tricycle, the discharge current is large, clear fever or fever deformation, then lead sulfate concentration is particularly large, the likelihood of survival short dendrites increases, besides point lead sulfate will crystallize into larger particles, which form irreversible sulfate, will further increase the resistance, charge recovery is poor, even beyond repair. Battery should be used to prevent over-discharge, to take "under-voltage protection" is a very effective measure. Also 48v electric tricycle, due to the electric car "under-voltage protection" is controlled by the controller of all-electric tricycle, but some other device controller except as voltmeters, lights and other power appliances directly from the battery power, the power The supply is generally not subject to the controller to control the electric tricycle, electric lock switch once closed to start electricity. Although the current is small, but if the discharge time of 1-2 weeks will be over-discharged. So, not a long lock, should not turn off immediately.
