Electric vehicle batteries and chargers Maintenance Code

To a dedicated charger, do not arbitrarily replace the charger

Chargers parameters with different models are basically not the same, there is no certainty when not arbitrarily replace the charger. If you must charge in both places, then the best professionals in the service department with a dedicated charger.

Protect the charger

The charger is not designed as a vehicle charger in the design, so now the charger basically intolerant strong vibration, and therefore generally do not put the charger in the trunk of electric bicycles and cars basket. Under special circumstances, must be moved, but also make good use charger packing foam to prevent the occurrence of vibration and bumps. After a lot of vibration through the charger, the internal potentiometer drift, making the parameter changes, resulting in abnormal state of charge. Also to be noted is to keep the charger when charging ventilation, otherwise not only affect the service life of the charger, the charging status can also affect the thermal drift, which would damage the battery is formed. (Generally involve manual charger)

Handling charge

Even if you do not continue the mileage requirements grow, you can use one charge 2-3 days, we recommend that you charge every day, so that the battery in the light cycle, the battery life will be extended. Some of the early use of mobile phone users is essential that the best use after battery recharge finished, this view is wrong, and memory benefits of lead-acid batteries are not so strong. Often put electricity and then charge the battery life impact is relatively large. After the charger indicator lights indicate fully charged, the battery charge into the charge may be 97% to 99%. Although only due to charge 1% to 3% of the electricity, the impact on the continued ability of the line is almost negligible, but also form due to charge accumulation, so the battery is fully charged after the lights change or continue to be floating charge as much as possible, but also to suppress cell cure good. Basic floating charge is not power.

Timely charge

Battery discharge after the curing process begins, generally beginning at 12 hours, there is a clear sulfide crystals. Timely charge, you can clear sulfide crystals are not serious, if not promptly charged, these sulfide crystals will gradually accumulate to form coarse crystals will gradually decrease battery capacity and shorten the battery life. So in addition to a daily charge, but also pay attention to timely charge after use is over, as far as possible in a full battery charge status.

Periodic deep discharge

A deep discharge battery regularly is also conducive to "activate" the battery, you can slightly enhance the capacity of the battery. The general approach is regularly once the battery is fully discharged. The method is fully discharged under normal load conditions flat road ride to the first undervoltage protection. Note: we emphasize first undervoltage protection. After the first battery voltage protection, battery after a period of time, the voltage will rise, and revert to a non-voltage state, at this time if we use the battery, the battery damage is very large. After completion of the full discharge, the battery is fully charged. Will feel the battery capacity has improved.

Develop some good habits of saving

Use glide as far as possible. Follows the slope of the time, as far as possible in advance of the use of power coastdown. When will encounter traffic lights ahead into glide, to minimize brake. Started, slowly turn the switch, so relatively safe, avoid large current impact on the battery, and can reduce battery life loss and damage.

Note that the charging environment

Currently electric car chargers are designed according to the ambient temperature of 25 ℃, 25 ℃, so in charge better. The ambient temperature is actually relatively small when 25 ℃, so it will have a summer and winter due to charge overcharge problem. So when charging the battery and charger is best placed in ventilated and temperature environment to use. (Indoor ventilation better place)

Special Note: In the outdoor cold northern winter, when the state into a warm room, the surface of the battery as the battery will appear in frost condensation. To avoid battery leakage caused by frost condensation, should the battery temperature rises to close to room temperature and dried again after charging.

Make full use of the maintenance condition

Electric car dealers can provide both battery testing and maintenance services, should take advantage of these services. Such as: regular battery maintenance can reduce damage to the battery. The battery state of charge of the repair can alleviate the "battery backward" failure. For water loss, in 70% of the battery capacity when water would be better than 40% of the battery capacity when the water effect. Therefore, consumers should be fully utilized to increase battery access conditions to extend battery life.

Through these methods, you can greatly extend battery life. Some users continue the mileage is relatively short, relatively long battery life, some problems are relatively difficult to find. Therefore, the "deep discharge" Measures mentioned earlier is also an effective way to detect problems with a battery (battery judge to continue the mileage), do not wait for the battery when it is a serious problem to repair, so it is difficult to deal with.
