Battery maintenance of electric motorcycles is the most critical

1. Do not change the charger casually, and do not remove the speed limit of the controller.
Each manufacturer's charger generally has individual needs, so don't replace the charger at will when you are not sure. If the driving mileage requirement is relatively long and multiple chargers must be equipped for off-site charging, use an additional charger to supplement charging during the day, and use the original charger at night. Although removing the speed limit of the controller can increase the speed of some cars, it will not only reduce the safety of the car, but also reduce the service life of the battery.
2. Protect the charger.
The general user manual has instructions on protecting the charger. Many users do not have the habit of reading the manual. They often think of looking for the manual only after problems arise. Often it is too late, so it is very necessary to read the manual first. In order to reduce costs, current chargers are basically not designed to be highly resistant to vibration. Therefore, chargers are generally not placed in the trunk or basket of electric bicycles. In special circumstances, if it must be moved, the charger must be packed in foam to prevent vibration and bumps. After many chargers vibrate, their internal potentiometers will drift, causing the entire parameters to drift, resulting in abnormal charging status. Another thing to note is to keep the charger ventilated when charging. Otherwise, it will not only affect the life of the charger, but also cause thermal drift and affect the charging status. This will cause damage to the battery. Therefore, it is also very important to protect the charger.
3. Charge it every day.
Even if your battery life requirement is not long and the battery can be used for 2 to 3 days on a single charge, it is still recommended that you charge it every day. This will keep the battery in a shallow cycle and extend the battery life. Some early users of mobile phones think that it is best to recharge the battery after it is basically used up. This view is wrong. The memory effect of lead-acid batteries is not that strong. Frequent discharge has a greater impact on the life of the battery. In most chargers, after the indicator light changes to indicate full charge, the battery may be charged to 97% to 99% capacity. Although the battery is only undercharged by 1% to 3%, the impact on the battery continuation capacity is almost negligible, but it will also cause accumulation of undercharge. Therefore, after the battery is fully charged, float charging should be continued as much as possible, which is also effective in inhibiting battery sulfuration. beneficial.
4. Charge in time.
The vulcanization process begins after the battery is discharged, and obvious vulcanization occurs after 12 hours. Charging in time can remove minor sulfide. If not charged in time, these sulfide crystals will accumulate and gradually form coarse crystals. General chargers are powerless against these coarse crystals, which will gradually cause the battery capacity to decrease and shorten the battery life. Battery life. Therefore, in addition to charging every day, you should also pay attention to charging as soon as possible after use to keep the battery as full as possible.
5. Regular deep discharge.
Regular deep discharge of the battery can also help "activate" the battery and slightly increase the battery's capacity. The general method is to completely discharge the battery regularly. The method of complete discharge is to ride to the first under-voltage protection on a flat road under normal load conditions. Note that we particularly emphasize the first undervoltage protection. After the battery is under voltage protection for the first time, the battery voltage will rise after a period of time and return to the non-undervoltage state. If the battery is used again at this time, it will cause great damage to the battery. After complete discharge, fully charge the battery, and you will feel that the battery capacity has increased.
6. Develop some good energy-saving habits.
Take advantage of gliding whenever possible. When going downhill, try to use early power outage to coast and slow down.
When you are about to encounter a traffic light, enter the taxi in advance to minimize braking. A friend told me that he would rather make one more turn than brake one less time. This makes sense. When starting, it is best to add riding assistance, which can not only increase the starting speed, but also reduce battery power loss and life damage.
7. Pay attention to the charging environment.
The optimal ambient temperature for charging is 25°C. Most chargers now do not have automatic control systems that adapt to the ambient temperature, so most chargers are designed according to the ambient temperature of 25°C, so charging is better at 25°C. Otherwise, problems of undercharging in winter and overcharging in summer will inevitably occur. When the ambient temperature is really low at 25°C, there will inevitably be problems of overcharging in summer and undercharging in winter. Fortunately, most homes now have indoor temperature control conditions. In this way, when charging, it is best to arrange the battery and charger in a ventilated and temperature-controlled environment. A special reminder from Shunling Electric Vehicles is that when the battery is placed in a warm room at low outdoor temperatures in northern winter, frost and condensation will appear on the surface of the battery. In order to avoid battery leakage caused by frost and condensation, the battery should be charged after the battery temperature rises to close to the indoor temperature and is dry.
8. Make full use of maintenance conditions.
Many electric bicycle dealers can provide battery inspection and repair services, and you should make full use of these services. Some brands of electric bicycles require battery maintenance. For example, regular maintenance of the battery can reduce damage to the battery. Repairing the battery's state of charge can alleviate "battery lagging" failures, and these are easy for dealers equipped with repair capabilities. For water loss, replenishing water when the battery capacity is 70% is better than replenishing water when the battery capacity is 40%. Some brands of products even propose that failure to perform maintenance within the specified time is equivalent to giving up the battery's warranty period. causing consumers to suffer losses that should not occur. Therefore, consumers should make full use of battery maintenance conditions to extend the service life of the battery.
