8 questions about electric vehicle batteries

1. Check whether there is any aging or short circuit in each part of the circuit to prevent the battery from being decommissioned early due to over-discharge.　　 2. The battery is not used for a long time, it will slowly discharge by itself until it is scrapped. Therefore, the car should be started every once in a while to charge the battery. Another way is to unplug the two electrodes on the battery. It should be noted that the positive and negative electrode wires should be unplugged from the electrode column. The negative wire must be unplugged first, or the connection between the negative electrode and the chassis of the car must be unplugged, and then Then unplug the other end with the positive sign (ten). The accumulator has a certain service life and needs to be replaced after a certain period of time. The above sequence should also be followed when replacing, but when connecting the electrode wires, the sequence is exactly the opposite, first connect the positive electrode, then the negative electrode.　　 3. The density of the electrolyte should be adjusted according to the standards in different regions and different seasons.　　 4. The storage capacity of the battery can be reflected on the dashboard. When the ammeter pointer shows that the battery is insufficient, charge it in time. Sometimes it is found that the battery is not enough on the road, and the engine can’t start when it stops. As a temporary measure, you can ask other vehicles for help. Use the batteries on other vehicles to start the vehicle. Connect the negative and negative electrodes of the two batteries, and the positive and positive electrodes. .　　 5. Check whether the positive and negative electrodes of the battery are oxidized. You can use hot water to pour the battery wire connections from time to time.　　6. u200bu200bWhen starting the car, uninterrupted use of the starter will cause the battery to be damaged due to over-discharge. The correct way to use it is that the total time to start the car each time is no more than 5 seconds, and the interval between restarts is no less than 15 seconds. In the case that the car cannot be started after multiple starts, the reason should be found from other aspects such as the circuit, the ignition coil or the oil circuit.　　7. Distilled water or special rehydration should be added when the electrolyte is depleted. Do not use pure drinking water instead, because pure water contains many trace elements, which will cause adverse effects on the battery.　　 8. You should always check whether the small holes on the battery cover are ventilated during daily driving. If the small holes on the battery cover are blocked, the hydrogen and oxygen produced cannot be discharged. When the electrolyte expands, the battery shell will be broken and affect the battery life.
