Electric vehicle batteries can be seen everywhere in our daily lives. It is related to the people’s travel, two-wheeled electric vehicles. It is a more convenient tool. It is a powerful tool. Its power is mainly based on the battery. The price of electric car is directly affected by electric vehicle manufacturing cost. At present, it is generally lead-acid, lead-carbon battery, and lead material prices can be said to be directly related to the secondary market to replace the battery price.
The following Xiaobian briefly says that there is a knowledge of electric vehicle battery maintenance:
If the electric vehicle battery is low, charge should be charged in time. It should be avoided to complete the vehicle completely, and cannot be moved.
The controller has an undervoltage protection function, and when the single voltage reaches 10.5V, the controller is powered down to protect the battery. Statically, the battery voltage rebounds. It can be short-lived, but this method is very large to cause battery life, which will cause battery life and severe shortening.
When riding during the winter, the life will be significantly shortened, the lower the temperature, the more obvious. This is a normal phenomenon, waiting for the weather to fall, the temperature rises above 20 degrees, the battery capacity will return to normal level.
When the vehicle is not riding for a long time, the battery must be fully charged. And the connection between the batteries is disconnected, if it is in the car, open the empty open. One month and two months should be charged once, and it will be opened after it is filled. Battery long-term loss should be avoided, resulting in a battery polarized sulfate, thereby shortening life.
The battery will have self-discharge situations regardless of the old and last time. The battery is seriously lost to 7V, which can cause the battery to charge. Even if you want to take it, you can also generate unable to recover damage.
When charging, the battery shell should be detected in time when the battery case is hot or charger does not turn green light. Under normal circumstances, there will only be slight fever when the battery is charged, and the charger should also turn to the green light after the battery is full. If it is not turned to the green light (generally 8-10 hours), it should be checked whether the charger has problems.
Should be avoided, under the sun, charging. The charger is afraid that the water will know. Because inside is a circuit board, it belongs to electronic components, which is strictly forbidden to dip. But try not to charge when thundering. At this time, it is easy to charge the charger being burned, and even the controller can be burned together.
Precautions for using electric vehicle batteries are as follows:
1. Don’t replace the charger casually, do not remove the speed limit of the controller
Each manufacturer’s charger generally has a personalized demand. Do not replace the charger at will not be able to hold it when you are not grasp. If the mileage requirement is relatively long, you must charge a plurality of chargers to charge off-site, the charger that charges the charging during the day with additional chargers, and the original charger is used in the evening. Remove the speed limit of the controller, although the speed of some cars can be improved, in addition to the safety of the car, it will also reduce the service life of the battery.
2, protect the charger
The general user instructions are related to the instructions for protecting the charger. Many users don’t look at the habits of the manual. In addition to the problem, I want to find a manual to see, it is too late, so I will first look at the instructions. In order to reduce costs, the current charger is basically not designed for high vibration, so that chargers generally do not put in the trunk and basket of electric bicycles. In special cases, it is necessary to move, but also pack the charger with foam plastic to prevent the bumps of vibration. Many chargers have passed vibration, and their internal potentiometers will drift, so that the entire parameter drift, resulting in abnormal charging state. In addition, it is necessary to pay attention to the ventilation of the charger when charging, otherwise it will not only affect the life of the charger, but also the thermal drift can affect the charging state. This will form damage to the battery. Therefore, it is also very important to protect the charger.
3, charge every day
Even if your renewal capacity is not required, it is 2 to 3 days, but it is recommended that you charge each day, so that the battery is in a shallow cycle, the battery life will be extended. Some early use of mobile phone users think that the battery is basically used in the future, and this view is wrong. The memory benefits of lead-acid batteries are not so strong. It is often more affected by the life of the battery. Most chargers indicate that the light-made lamp is fully charged, the battery can be charged in an electric charge may be 97% to 99%. Although only 1% to 3% of the electricity, the impact of the continuation capacity is almost neglected, but it will also form an under charge accumulation, so the battery is filled with the electric shifting, and the floating charge will be continued as much as possible, and the vulcanization of the battery is also beneficial.
4, charge in time
After the battery discharge, the vulcanization process is started, and there is a significant vulcanization in 12 hours. Timely charging, you can remove unscrupulous vulcanization, if it is not charged, these vulcanized crystals will gradually form a coarse crystallization, and the general charger is impossible for these coarse crystals, which will gradually form a decrease in battery capacity, shortened. The battery life is used. Therefore, in addition to charging daily, pay attention to the use of the time to charge, so as to make the battery power in full.
5, periodically deep discharge
The battery regularly performs a deep discharge is also conducive to the ‘activated’ battery, which can slightly improve the capacity of the battery. The general method is to periodically discharge the battery once. The fully discharged method is to ride the first undervoltage protection under the normal load of flat pavement. Note that we especially emphasize the first undervoltage protection. After the battery is protected for the first time, the battery will rise after a period of time, and it is restored to the non-radical state, and if the battery is used, the battery is very harmful. After completing complete discharge, the battery is fully charged. It will feel that the battery capacity has improved.
6, develop a good habit of some power saving
Use it as much as possible. When the slope is used, as much as possible is used to cut off the pulley. In advance when you encounter the traffic light, you will enter the sliding, minimize the brakes. A friend told me that he would rather turn more than one bay and reducing a brake, which is reasonable. When starting, it is best to join riding boost, not only the start speed, but also reduce the battery loss and life damage.
7, pay attention to the environment of charging
The best ambient temperature charge is 25 ¡ã C. Now most chargers do not adapt to the ambient temperature automatic control system, and most chargers are designed according to the ambient temperature of 25 ¡ã C, so it is better to charge at 25 ¡ã C. Otherwise, it is inevitable that there is a problem in winter under charge and summer overcharge. The ambient temperature is really small at 25 ¡ã C, which necessarily has problems with under charge of charging in winter. Fortunately, most families have room temperature conditions, so that when charging, it is best to arrange the battery and charger in an environment with ventilation and temperature.
Specially suggest that the battery is in a warm room in the northern winter, and there will be frosting. In order to avoid the leakage caused by frosting condensation, it should be charged after the battery temperature is close to the indoor temperature and drying.
8, make full use of maintenance conditions
A lot of electric bicycles can provide battery overhaul and service, which should make full use of these services. Some brands of electric bicycles put forward the overhaul of the battery. Such as: Regularly overhaul the battery can reduce damage to the battery. The repair of the charge state of the battery can alleviate the failure of the backward ‘of the battery, and these dealers equipped with maintenance capacity are light. For downtime, it is better to hydrophone when hydrating is 40% of the battery capacity of 70%. Even some brands of products also proposed: to the specified time is not overhaul, which is equivalent to giving up the battery. Enables consumers that should not occur. Therefore, consumers should fully utilize the conditions of battery overhaul to increase the life of the battery.
By these methods, the user can greatly extend the battery life of the battery. Some users have a shorter mileage, and the battery life is relatively long, and some problems are relatively difficult to find. Therefore, the ‘deep discharge’ measures that are said to be discovered in time, it is difficult to handle when the battery problem is seri
