It is strictly forbidden to lose electricity during storage: the battery is strictly prohibited from being in the state of power loss when it is stored. The power-loss state is that the battery is not charged in time after use. In the state of loss of electricity, sulfation is easy to be stored, lead sulfate crystals are attached to the plate, and the electric ion channel is blocked, and the charge is insufficient and the capacity of the battery is reduced. The longer the idle time of the power loss state is, the more serious the battery damage is. Therefore, when the battery is idle, it should be charged once a month, so that the battery can be kept healthy.
Two, regular inspection: in the process of use, if the electric vehicle's continued mileage suddenly drops more than ten kilometers in a short time, it is very likely that there is a short circuit in the battery group with the least one battery broken, the plate softening, the plate active material fall off and so on. At this point, professional battery repair institutions should be inspected, repaired or matched in time. This can prolong the life of battery pack and save the most.
Three, avoid large current discharge: when starting an electric vehicle, carrying a person or uphill, use pedal power to avoid instantaneous large current discharge. Large current discharge easily leads to crystallization of lead sulphate, thereby damaging the physical properties of the battery electrode.
Four, to grasp the charging time correctly: in the process of use, we should grasp the charging time accurately according to the actual situation, refer to the usual use frequency and mileage, and also pay attention to the capacity description provided by the battery manufacturer, as well as the performance of the auxiliary charger, the small charge current and so on. In general, batteries are charged at night, and the average charging time is about 8 hours. If a shallow discharge (a short distance after charging), the battery will soon fill up, and continue charging will be overcharged, causing the battery to lose water, heat, and reduce battery life. Therefore, the battery can charge the best charge once the discharge depth is 60%-70%, and it can be converted into riding mileage when used in actual use. It can be charged according to the actual situation and avoid the harmful charging.
Five, to prevent exposure: electric vehicles are strictly prohibited in the sun exposure. The high temperature environment will increase the internal pressure of the battery and make the battery limit pressure valve open automatically. The direct consequence is to increase the amount of water loss of the battery, and the excess water loss of the battery will inevitably lead to the decrease of the battery activity, the softening of the plate, the heating of the shell and the fatal damage of the shell, such as the drum, the deformation and so on.
Six. To avoid the plug heating when the charging is avoided: the loosening of the charger output plug and the oxidation of the contact surface all lead to the heating of the charging plug. The excessive heating time will lead to the short circuit of the charging plug, which directly damages the charger and brings unnecessary losses. Therefore, we should remove oxides or replace connectors in time.
