Electric Motorcycle Factory introduces the maintenance of electric vehicles, the following items must be noted:1. If the battery of an electric car 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 of the electric car. Another way is to unplug the two electrodes from the battery of the electric vehicle. What should be paid attention to is to unplug the positive and negative electrode wires from the electrode column, first unplug the negative wire, or disconnect the negative electrode and the car chassis. , And then unplug the other end with the positive sign (ten).2. The battery of an electric vehicle 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 storage capacity of the electric vehicle 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 after it stops. As a temporary measure, you can ask other vehicles for help. Use the electric vehicle batteries on other vehicles to start the vehicle, and connect the negative and negative electrodes of the two electric vehicle batteries. The positive pole is connected to the positive pole.4. The density of the electrolyte should be adjusted according to the standards in different regions and different seasons.5. When the electrolyte is depleted, distilled water or special rehydration should be added. Do not use pure drinking water instead, because pure water contains a variety of trace elements, which will cause adverse effects on electric vehicle batteries.6. When starting the car, uninterrupted use of the starter will cause damage to the battery of the electric car due to excessive discharge. The correct way to use it is that the total time for each start of the car should not exceed 5 seconds, and the interval between restarts should not be 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. Check whether the positive and negative electrodes of the battery are oxidized. You can often pour the wire connections of the battery with hot water.8. 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 excessive discharge.9. During daily driving, check whether the small holes on the battery cover of the electric vehicle are ventilated. If the small holes of the battery cover of the electric vehicle are blocked, the generated hydrogen and oxygen cannot be discharged. When the electrolyte expands, it will support the battery shell of the electric vehicle. Broken, affecting the battery life of electric vehicles.Through the above introduction, High Speed Electric Motorcycle Manufacturers hopes that you can simply refer to the content of this article in future use.
