Correct Use of Batteries in EV Primary Cylindrical Lithium Sulfur Dioxide Cell

Overview:Each manufacturer's generally have personalized designs for the charger. So do not change chargers at will when you are uncertain. If the mileage requirement is relatively long, it is necessary to equip several chargers for charging in different places. The charger that recharges during the day will be used as a supplementary charger, while the charger that recharges at night will be used as a supplementary charger. Removing the speed limit of the controller can improve the speed of some cars, which will not only reduce the safety of the car, but also reduce the service life of the battery.

1. Don't change the charger casually, don't remove the speed limit of the controller.


Each manufacturer's generally have personalized designs for the charger. So do not change chargers at will when you are uncertain. If the mileage requirement is relatively long, it is necessary to equip several chargers for charging in different places. The charger that recharges during the day will be used as a supplementary charger, while the charger that recharges at night will be used as a supplementary charger. Removing the speed limit of the controller can improve the speed of some cars, which will not only reduce the safety of the car, but also reduce the service life of the battery.


2. Protect the charger.


There are instructions on how to protect chargers in the general instructions. Many users do not have the habit of reading the instructions, often in addition to problems before they think of looking for instructions to read, often too late, so it is necessary to read the instructions first. In order to reduce the cost, the charger has not been designed to withstand high vibration. In this way, the charger should not be placed in the backup box and basket of the electric bicycle. Under special circumstances, it is necessary to move and pack the charger with foam plastic to prevent vibration bumps. After many chargers are vibrated, their internal potentiometers will drift, making the whole parameters drift, resulting in abnormal charging state. In addition, it should be noted that the ventilation of the charger should be maintained when charging, otherwise not only the life of the charger will be affected, but also the charging state may be affected by thermal drift. This will cause damage to the battery. Therefore, it is very important to protect the charger.


3. Charge regularly.


Even if you don't require long service life and can be charged for 2 to 3 days at a time, it is recommended that you charge every day, so that the battery is in a shallow cycle state, and the battery life will be prolonged. Some early mobile phone users believed that the best way to recharge batteries was to recharge them after they had basically finished using them. This view is incorrect. The memory benefits of lead-acid batteries are not so strong. Frequent discharge of electricity has a greater impact on battery life. Most chargers charge 97%-99% of the battery after the indicator lamp changes to indicate full charge. Although only 1%-3% of the charge is under-charged, the effect on the continuity ability can be neglected, but it will also form under-charged accumulation, so the battery will continue to float charging as far as possible after it is full of electric lamp, which is also good for restraining battery vulcanization.

4. Timely charging.


The vulcanization process begins after the battery discharges, and obvious vulcanization occurs at the beginning of 12 hours. Charging in time can remove the less serious sulfide. If not charged 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 the service life of batteries. Therefore, in addition to charging every day, we should also pay attention to charging as soon as possible after use, so as to make the battery capacity in full state.


5. Regular deep discharge.


Regular deep discharge of the battery is also conducive to "activation" of the battery, which can slightly increase the capacity of the battery. The general method is to discharge the battery completely periodically. The method of complete discharge is to cycle to the first undervoltage protection under normal load on flat road. Note that we particularly emphasize the first undervoltage protection. After the first undervoltage protection, after a period of time, the battery voltage will rise and return to the non-undervoltage state. At this time, if the battery is used again, it will cause great damage to the battery. If the battery is used several times, it may lead to the complete abandonment of the battery. After complete discharge, the battery is fully charged. It will increase the battery capacity.


6. Develop some good habits of saving electricity.


Use taxiing whenever possible. When the slope is below, make the best use of the power cut ahead of time to slide and decelerate. Enter taxiing ahead of time when you are about to encounter traffic lights to minimize braking. A friend told me that he would rather turn the Bay once more and reduce the brake once, which is reasonable.


When starting, it is better to add bicycle assistance, which can not only improve the starting speed, but also reduce the battery power loss and life damage.


7. Pay attention to the charging environment.


The optimum ambient temperature for charging is 25 C. At present, most chargers do not have an automatic control system adapting to the ambient temperature, so most chargers are designed according to the ambient temperature of 25 degrees, so charging at 25 degrees is better. Otherwise, there will inevitably be problems of undercharging in winter and overcharging in summer. However, when the ambient temperature is really 25 degrees Celsius, there is a problem of overcharging in summer and undercharging in winter. Fortunately, most households now have indoor temperature control conditions, so when charging, it is best to arrange the battery and charger in a ventilated and temperature-adjusted environment.


Frost and condensation will occur on the surface of batteries when they enter the warm room in the cold outdoor state in winter in the north. In order to avoid leakage caused by frost condensation, the battery should be charged after the temperature rises to close to the indoor temperature and dries.


8. Making Full Use of Maintenance Conditions


Many distributors of electric bicycles can provide battery repair and repair services, which should be fully utilized. Some brands of electric bicycles have proposed battery repair.
