How To Make The Battery Life Of Electric Bicycles Longer?
Nowadays, electric bicycles have become a transportatio […]
Nowadays, electric bicycles have become a transportation tool for people to travel, but for users, the cost of batteries is the largest consumption of electric bicycles, so people are very concerned about extending the life of batteries. First of all, it is assumed that there is no problem with the charger. Whether the user uses it correctly is crucial to the life of the battery.
1. Don't charge every day
Many so-called experts suggest that "if you use an electric car for a long time (that is, only a little electricity is used every day), but it is recommended that you charge it every day, so that the battery is in a shallow cycle and the battery life will be extended." In fact, this argument is not quite right. At present, most electric vehicles use lead-acid batteries, which have a certain charging life, and excessive frequent charging will affect the life of electric vehicle batteries.
So when does it generally charge? According to the recommendations in the battery manual: recharge when there is about 1/4 of the battery left.
2. Check the manual of the charger
The general instruction manual has instructions on protecting the charger. Many users do not have the habit of reading the manual, and often think of looking for the manual only after the problem. It is often too late, so it is very necessary to read the manual first.
The chargers of various manufacturers generally have personalized needs. Do not replace the chargers at will when you are not sure. If the continuation mileage requirement is relatively long, multiple chargers must be equipped for off-site charging, and the chargers that make up the charge during the day will be supplemented by another supplementary charger, and the original charger will be used at night.
In order to reduce costs, the current chargers are basically not designed to withstand high vibrations. In this way, the chargers are generally not placed in the trunk and basket of electric bicycles. Under special circumstances, it must be moved, and the charger must be wrapped in foam plastic to prevent vibration and bumps. After many chargers are vibrated, the internal potentiometer will drift, causing the entire parameter to drift, resulting in an abnormal charging state.
3. If you don't use it for a long time, you should charge it regularly
If you plan to change your work or the weather gets colder and you have an electric car that you will not use for a long time, we recommend that you recharge your electric car every 10-15 days or so. Don't manage your electric car for a long time, as the battery of the electric car is very easy to damage.
Because the electric vehicle is placed for a long time, the battery of the electric vehicle will slowly discharge itself. After the battery is discharged, the vulcanization process begins. At 12 hours, obvious vulcanization occurs.
Charging in time can remove minor sulfide. If not charging in time, these sulfide crystals will accumulate and gradually form coarse crystals. General chargers are powerless to these coarse crystals, which will gradually form a decline in battery capacity and shorten Battery life. Therefore, in addition to charging the battery regularly, it should also be noted that after use, it should be charged as soon as possible to keep the battery full.
4. Do not remove the speed limit of the controller
If you want to protect your battery, do not remove the speed limit of the controller.
Remove the speed limit of the controller, although it can increase the speed of some cars, in addition to reducing the safety of the car, it will also reduce the service life of the battery. In addition, it should be noted that the charger must be ventilated during charging, otherwise it will not only affect the life of the charger, but may also cause thermal drift and affect the charging state. This will damage the battery. Therefore, it is also very important to protect the charger.
5. Pay attention to the charging environment
The best environment for battery maintenance and charging is 25 ℃.
At present, most chargers do not have an automatic control system adapted to the ambient temperature, so most chargers are designed according to the ambient temperature of 25 ° C, so charging at 25 ° C is better. Otherwise, the problems of undercharging in winter and overcharging in summer are inevitable.
When the ambient temperature is really less than 25 ℃, there will be a problem of overcharging in summer and undercharging in winter. Fortunately, most households now have indoor temperature adjustment conditions, so when charging, it is best to arrange the battery and charger in a ventilated and temperature-adjusted environment.
Special reminder: when the battery is in the northern low temperature state and enters the warm room in winter, frost and condensation will appear on the surface of the battery. In order to avoid the battery leakage caused by frost and condensation, the battery should be charged after the battery temperature rises close to the indoor temperature and is dry.
6. Regular deep discharge
A deep discharge of the battery on a regular basis is also beneficial for "activating" the battery, which can slightly increase the capacity of the battery.
The general method is to periodically discharge the battery once. The method of complete discharge is to ride to the first under-voltage protection under the condition of normal load on a flat road. Note that we particularly emphasize the first undervoltage protection.
After the first undervoltage protection of the battery, after a period of time, the voltage of the battery will rise and return to the non-undervoltage state. If the battery is used again at this time, the battery will be greatly damaged. After complete discharge, fully charge the battery. You will feel the battery capacity has improved.
7. Make full use of maintenance conditions
Many electric bicycle dealers can provide battery repair and maintenance services, and these services should be fully utilized.
Some brands of electric bicycles have proposed overhaul of batteries. Such as: regular maintenance of the battery can reduce damage to the battery. Repairing the state of charge of the battery can alleviate the "backward battery" failure, and these are easy for dealers equipped with maintenance capabilities.
For water loss, water replenishment when the battery capacity is 70% is better than water replenishment when the battery capacity is 40%. Even some brands of products have proposed that the maintenance period is equivalent to abandoning the warranty period of the battery until the specified time. Consumers suffer losses that should not occur. Therefore, consumers should make full use of the conditions for battery maintenance to extend the life of the battery.
Through these methods, users can greatly extend the life of the battery. Some users have a relatively short continuation mileage, a relatively long battery life, and some problems are relatively difficult to find. Therefore, the "deep discharge" measures mentioned in Article 4 are also an effective way to discover battery problems in time. Don't wait for battery maintenance to be difficult when the battery problem is serious.
8. Develop a good habit of saving electricity
Everyone should develop some good habits of saving electricity when using electric vehicles. For example, use taxiing as much as possible; when downhill, make use of early power off to slow down as much as possible; when you are about to encounter a traffic light, enter the taxi ahead of time to minimize braking.
A friend told me that he would rather turn one more turn and reduce the brakes. This makes sense. When starting, it is best to add riding assistance, not only can increase the starting speed, but also can reduce battery power loss and life damage.
As long as the above 8 points are completed, the battery life of your electric vehicle will be greatly strengthened, and it will be no problem for 2 to 2.5 years.
