1, should be fully charged before use. Newly purchased electric vehicles should be fully charged before use. Because many electric vehicles have been put on hold for a few months or even more than half a year in the store, they must be fully charged before use. After fully charged, it is best not to use them immediately. It should be left for about ten minutes.
2. The battery should be installed firmly on the electric bicycle. The battery is taken down and charged. When installing, the battery should be installed firmly on the electric bicycle to prevent the battery from being damaged by vibration during riding. When the battery is being transported, it is forbidden to throw, roll, or press.
3. Keep the battery dry and clean. Always remove dust and dirt from the battery cover, and keep the battery dry and clear to prevent the battery from discharging itself.
4. Develop a good habit of charging the battery every night. Never let the battery be under-charged for a long time, and develop a good habit of charging the battery every night. Long-term use, should be fully charged, placed in a cool dry place, and charged regularly, usually 10 days.
5, just start using the pedal. When the electric bicycle is just starting, use the pedals. If there is no pedal, you can use the foot to push the ground to help start. When going uphill, use the pedals to help the electric vehicle to go uphill to avoid excessive discharge current and damage the battery.
6, can not let the battery over discharge, so shallow and diligent. When riding, be careful not to over discharge the battery. After the battery is discharged to the termination voltage, the discharge is called overdischarge. Over-discharge easily causes serious battery losses, which greatly shortens its service life. Therefore, the battery should be used to avoid deep discharge when using it. It should be done shallowly and diligently. Generally, the battery should be charged with the best charge when the discharge depth is 50%. Under-voltage protection is generally provided on electric bicycles. When only one indicator light is on, the battery should be turned off, use the pedals, and try to charge the battery as soon as possible to avoid over-discharging the battery.
7. The battery should not be unlocked for a long time, and should be turned off immediately when not in use. When the voltage is terminated, the internal resistance is large, the electrolyte concentration is very thin, especially in the pores and the surface of the plate is almost neutral. When the over-discharge, the internal resistance has a tendency to heat, the volume expands, and when the discharge current is large, the heat is even hot. When the heat is deformed, the concentration of lead sulfate is particularly large, and the possibility of survival of the short circuit of the crystal branch is increased. At this time, lead sulfate crystallizes into larger particles, which forms irreversible sulfation, which further increases the internal resistance, and the charge recovery ability is very high. Poor, not even fixable. When the battery is used, it should prevent over-discharge. It is a very effective measure to take "undervoltage protection". In addition, since the electric vehicle "undervoltage protection" is controlled by the controller, other devices other than the controller, such as voltmeters, indicator lights, etc., are directly powered by the battery, and the supply of the power supply is generally not controlled. Control, the electric lock switch will start to use electricity once it is closed. Although the current is small, overdischarge occurs if it is discharged for 1-2 weeks. Therefore, it is not allowed to unlock for a long time, and should be turned off immediately when not in use.
8. Avoid overcharging. When the charger is full, it stops charging, and you can't charge it overnight or even a few days. Over-charging will cause the active material of the plate to harden and fall off, and cause water loss and battery deformation. The battery runs during the hot season, and there is mainly a problem of overcharging. Therefore, in summer, the battery temperature should be reduced as much as possible to ensure good heat dissipation, to prevent charging after sun exposure, and to keep away from heat. Avoid overcharging, and choose the charger parameters to match the battery well. It is necessary to fully understand the battery's operating conditions during the hot season and the changes during the entire service life. Do not leave the battery in an overheated environment during use, especially when charging. Keep away from heat. After the battery is heated, it should take cooling measures, and the battery can be charged only when the battery temperature returns to normal. The installation position of the battery should ensure good heat dissipation as much as possible. When it is overheated, stop charging and check the charger and battery. The charging time should be shortened when the battery discharge depth is shallow or when the ambient temperature is high.
