Some issues that need attention in the use and maintenance of car rechargeable battery
① If the car rechargeable battery is not used for a long time, the battery will self-discharge until it is scrapped. Therefore, it is necessary to start the car and the car’s rechargeable battery at intervals. Another way is to unplug the positive and negative electrode wires from the electrode column on the car rechargeable battery. Pay attention to first unplug the negative wire or disconnect the negative pole and the car chassis, and then unplug the positive pole sign ( +) of the positive wire. Car rechargeable batteries need to be replaced after a certain period of use, because batteries have a service life. When replacing the car rechargeable battery, follow the above steps, but when reconnecting the electrode wire to the car, you need to connect the positive electrode and then the negative electrode.
②When the ammeter pointer on the car shows that the car rechargeable battery is insufficient, it needs to be charged in time. The charge of the car’s rechargeable battery can be seen on the dashboard. In normal life, if you find that the battery is not enough to get you to the destination and charging location while driving an electric car, and the engine cannot be started because of stalling, you can use a temporary solution to ask other electric car owners for help and use their car to charge. The battery helps to start the vehicle by connecting the positive pole and the positive pole of the two car rechargeable batteries, and the negative pole and the negative pole, through the power transmission, to help start the car and so on.
③The density of the electrolyte should be adjusted accordingly in accordance with the standards in different regions and different seasons. For example, a relatively high density electrolyte should be used in cold areas; when in the same area, the relative density of the electrolyte in winter should be 0.02～0.04 higher than in summer.
④ When the electrolyte is depleted, special replenishment liquid or distilled water should be given, and it is forbidden to use pure drinking water as a substitute for replenishment. Because drinking purified water contains many kinds of trace elements, and these elements can cause damage to car rechargeable batteries.
⑤When starting the car daily, it is best not to start the car uninterruptedly, because this approach will cause the car’s rechargeable battery to be damaged due to over-discharge. The standard method of use is that the total length of each start of the car should be within five seconds, and the interval between restarts should be within 15 seconds. If the vehicle cannot be started even after multiple starts, the ignition coil, circuit or oil circuit should be used. Wait for other reasons to find out.
⑥ In the daily use of the vehicle, check the ventilation problem of the small holes on the car rechargeable battery cover frequently. If the small holes of the car rechargeable battery cover cannot be ventilated, the hydrogen and oxygen produced by it cannot be discharged, which will cause the electrolyte to expand, which may break the car rechargeable battery casing, thereby shortening the life of the car rechargeable battery.
⑦Occasionally, check the positive and negative levels of the car’s rechargeable battery for signs of oxidation during daily use of the vehicle. Method: When using hot water, often pour the battery wire connection.
⑧ Check whether there is aging or short circuit in each part of the circuit when using the vehicle daily. To facilitate vehicle maintenance and prolong life
