Lead-acid battery electric car charging before beginning initial charging prepare: Check lead-acid battery electric car parts are complete, complete, between the battery connections are correct, solid, unscrew the top of the battery of anti-acid tied, electronic battery, connect the screw Vaseline oil. Anode and cathode connected to a DC power source battery, a negative electrode connected to a DC power supply negative. Such as the use of constant current charging, electronic output voltage of the battery 4v, charging equipment should be 40% higher than the rated voltage of the battery pack: If constant voltage charging, the output voltage of the charging equipment should be 20% higher than the rated battery pack. Above content provided by Hebei Tianyi Electric Co., Ltd., we hope to help a friend in the same industry. Lead-acid battery electric car is what constitutes positive plate: as a cathode during discharge and during charging as a plate of the anode. Negative plate: an anode during discharge and during charging plate as a cathode. Partition: on the positive battery, electronic battery brand, between the negative electrode plate, allowing ions to pass through electrically insulating material components. It prevents the positive and negative plates are connected together. Electrolyte: containing mobile ions, to participate in the electrochemical reaction, electronic battery 12v, and play the role of the ionic conductivity of the liquid or solid phase material. Poles: battery with outer conductor connected components. Battery slot: battery pole accommodate groups from corrosion and electrolyte solution container. Battery cover: Parts closure battery slot with the injection hole and terminal extraction holes. Sealing agent: For battery slot with the cover, the cover and the terminal sealing material. Drain plugs: for closing the injection hole, while allowing gas to escape parts. Above content provided by Hebei Tianyi Electric Co., Ltd., we hope to help a friend in the same industry.
