Maintenance.
1. It should be fully charged before use. Newly purchased electric vehicles should be fully charged before use. Because many electric vehicles have been left in stores for several months, or even more than half a year, they must be fully charged before use. It is best not to use them immediately after fully charged, but to stand for about ten minutes.
2. The battery should be firmly installed on the electric bicycle. Take the battery down to charge. When installing, the battery should be firmly installed on the electric bicycle to prevent the battery from being damaged by vibration while riding. When the battery is being transported, it is forbidden to throw, roll over or press it heavily.
3. Keep the battery dry and clean. Frequently remove the dust and dirt on the battery cover, and keep the battery dry and clean to prevent the battery from self-discharging.
4. Develop a good habit of charging the battery every night. Never let the battery be in a state of low power for a long time, and develop a good habit of charging the battery every night. If it is not used for a long time, it should be fully charged, placed in a cool and dry place, and charged regularly, usually for 10 days.
5. Just start with a pedal. When the electric bicycle is just started, use the pedals. If you have no pedals, you can push the ground with your feet to help start. When going uphill, use the pedals to help the electric bike go uphill, so as not to damage the battery due to excessive discharge current.
6. Don’t let the battery over-discharge, do shallow discharge and frequent charge. When riding, be careful not to over-discharge the battery. After the battery is discharged to the cut-off voltage, continuing to discharge is called over-discharge. Over-discharge is likely to cause severe power loss of the battery, which greatly shortens its service life. Therefore, when using the battery, you should try to avoid deep discharge, and do shallow discharge and frequent charging. In general, it should be done. It is best to charge the battery once when the discharge depth is 50%. Electric bicycles are generally equipped with an undervoltage protection function. When only one indicator light on the battery level indicator is on, the power should be turned off, use the pedals, and try to charge the battery as quickly as possible to avoid over-discharge of the battery.
7. The battery should not be unlocked for a long time when it is discharged, and it should be turned off immediately when not in use. When the end voltage is reached, the internal resistance is relatively large, and the concentration of the electrolyte is very thin, especially the inside and surface of the electrode plate are almost neutral. During over-discharge, the internal resistance tends to generate heat, and the volume expands. Heating deformation, at this time the concentration of lead sulfate is particularly high, the possibility of short circuit of living dendrites increases, and at this time lead sulfate will crystallize into larger particles, that is, irreversible sulfation will be formed, which will further increase the internal resistance and the charging recovery ability will be very poor Poor, even beyond repair. The storage battery should be prevented from over-discharging when it is in use, and it is very effective to take “under-voltage protection”. In addition, since the “undervoltage protection” of the electric vehicle is controlled by the controller, but some other equipment other than the controller, such as voltmeters, indicator lights, etc., are directly powered by the battery, and the power supply is generally not controlled. Once the electric car lock switch is turned on, it starts to use electricity. Although the current is small, over-discharge will occur if it is discharged for a long time for 1-2 weeks. Therefore, it is not allowed to unlock for a long time, and it should be turned off immediately when not in use.
