How should the battery be used to maximize its use and extend its life? -Lithium - Ion Battery Equipment
The length of battery life depends on two reasons. The first is that there are quality problems in itself, resulting in reduced performance and short usage; the second is that car owners usually do not know how to take care of the battery and wear out the battery. How should batteries be used to maximize their use and extend their lifespan? Kuai Kian Momentum has compiled 12 relevant experiences:
1. Resolutely do not use inferior chargers, and resolutely do not use chargers with mismatched models. The charger technology is not complicated, but inferior charger circuit boards and electronic components will not be the best, or even unqualified. When faced with a voltage of 220V, these unqualified components will heat up and cause damage to themselves and the battery. A charger with a mismatched model will cause the battery to become useless.
2. Charging frequency and time are also very important for battery maintenance. When the power is lower than about 30%, it should be charged in time. Frequent charging will have a negative impact on the battery. Because long-term deep discharge or too shallow discharge will affect battery performance. If you drive more than 15 kilometers at a time, it is best to charge it in time and do not wait for the battery to be completely used up before recharging. It is understood that the battery performance is best when the battery is charged when 70% of the battery power is used up.(Lithium - Ion Battery Equipment)
3. If the battery is not used for a long time, it should be fully charged first and then recharged regularly. During the storage process, the battery's power will gradually decrease due to self-consumption. If it cannot be replenished in time, it will affect the performance of the battery. It is recommended to recharge it every 1-2 months.
4. 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.
5. Regular deep discharge of the battery will also help activate the battery and slightly increase the battery capacity. The method of deep 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, the battery is fully charged. You will feel that the battery capacity has been improved.
6. Do not drive overloaded or overweight, and try to avoid sudden braking. Frequent sudden braking will affect the braking flexibility and consume battery capacity; the vehicle speed should not be too fast. The faster the vehicle speed, the greater the loss of the battery. 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. 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. Frequently remove dust and dirt on the battery box, prevent direct sunlight from shining on the electric vehicle battery, and prevent rainwater from entering the battery box. These will have a negative impact on the performance of the battery and charger.
8. Prevent exposure to high temperatures. Electric vehicles are strictly prohibited from being exposed to the sun. An environment where the temperature is too high will increase the internal pressure of the battery and force the battery pressure limiting valve to open automatically. The direct consequence is the increased water loss of the battery. Excessive water loss in the battery will inevitably lead to a decrease in battery activity, accelerate the softening of the plates, and slow charging. The shell may become heated, bulged, deformed or otherwise cause fatal damage.
9. The temperature is high in summer. If an electric vehicle is driven for a long time or charged immediately after being exposed to the sun, it is easy to increase the temperature of the circuit and the motor. In severe cases, it may even cause the battery to crack or deform, causing circuit failure and spontaneous combustion. Be sure to wait two or three hours for the battery to cool down before charging; when charging, it is important to pay attention to whether the circuit is aging to prevent short circuits.
10. When charging an electric vehicle, the battery should be removed and charged separately as much as possible. The charging lines in the parking shed should choose appropriate wire diameters, the lines should be fixed and installed, and short-circuit and leakage protection devices should be installed. Vehicle charging should prevent the charging time from being too long. In principle, the charging time should not exceed 10 hours.
11. At present, electric vehicle batteries are generally lead-acid batteries, but most of the fast chargers on the market use high-voltage and high-current pulse charging. When charging with high current, it will accelerate the polarization speed of the battery plates and reduce the battery life.
12. During use, if the driving range of an electric vehicle suddenly drops by more than ten kilometers in a short period of time, it is likely that at least one battery in the battery pack has broken cells, the plates have softened, or the active material of the plates has fallen off, etc. short circuit phenomenon. At this time, you should go to a professional repair shop for inspection, repair or assembly in time.
