Do not charge in the sun in summer, and all electric vehicle batteries must be charged frequently. The charging time is best not to be too long and never exceed twelve hours. Pay attention to heat dissipation when charging. In addition, the depth of discharge and life span are very large. The relationship is how much electricity is left in your battery, which is why you charge frequently.
Note: It is strictly forbidden to lose power when the battery is stored. The state of power deficit means that the battery of an electric vehicle is not charged in time after use. When the battery is stored in a power-deficient state, it is prone to sulfation. Lead sulfate crystals adhere to the electrode plate, blocking the ion channel, causing insufficient charging and decreasing battery capacity. The longer the idle time in the power-deficient state, the more severe the battery damage. Therefore, when the battery is not in use, it should be recharged once a month to better maintain the battery health.
When the electric vehicle starts, carries people, or goes uphill, please use the pedals to assist, and try to avoid instantaneous high current discharge. High current discharge will easily lead to lead sulfate crystals, which will damage the physical properties of the battery plates.
Electric cars cannot be left outside when it is raining, which can easily lead to paralysis and break down too many times. It is not conducive to battery maintenance.
During use, if the continued mileage of an electric vehicle drops more than ten kilometers in a short period of time, it is very likely that at least one battery in the battery pack has short-circuit phenomena such as broken grids, softening of the plates, and falling off of active materials on the plates. . At this time, you should go to a professional battery repair organization for inspection, repair or assembly in time. This can relatively extend the life of the battery pack and save money to the greatest extent.
Always pay attention to the quality of the charger, so as not to have a certain impact on the maintenance of the electric vehicle and the combustion of the battery.
1. Do not store at a loss of electricity: the state of loss of electricity means that the battery of an electric vehicle is not charged in time after use, resulting in insufficient charging and a decrease in battery capacity. The longer the idle time in the deficient state, the more serious the battery damage. When the battery is not in use, it should be charged once a month, which can extend the battery life.
2. It is necessary to check regularly during use.
If the continued mileage of the electric bicycle drops by more than ten kilometers in a short period of time, it is very likely that at least one battery in the battery pack has broken grids, softened plates, and activated plates. Short-circuit phenomena such as material shedding. At this time, you should go to a professional battery repair organization for inspection and repair in time.
3. Do not discharge the electric bicycle with high current.
It is best to use the pedals to assist when starting, carrying people, or going uphill to avoid instantaneous high current discharge. High-current discharge can easily lead to lead sulfate crystallization, thereby damaging the physical properties of the battery plate.
4. Master the charging time.
Under normal circumstances, electric vehicle batteries are charged at night, and the average charging time is about 8 hours. If it is a shallow discharge (the mileage is short after charging), the battery will be fully charged soon, and overcharge will occur if the charging continues, which will cause the battery to heat up and reduce the battery life. Therefore, it is best to charge an electric vehicle battery with a discharge depth of 60%-70% (two bars down). It can be converted into a riding mileage in actual use, and necessary recharge according to the actual situation to avoid harmful charging.
5. Prevent high temperature exposure.
An excessively high temperature environment will increase the internal pressure of the electric vehicle battery and the battery pressure limiting valve will be forced to open automatically. The direct consequence is to increase the battery's water loss, and excessive battery loss will inevitably lead to a decrease in battery activity, accelerate the softening of the plate, and charge When the shell heats up, the shell bulges, deforms and other fatal injuries.
6. Charge the battery in winter, keep it indoors, and warm the battery for two hours before charging.
As the time of use, the battery of electric vehicles is not far away from Vietnam. This is normal, especially in cold weather. Generally, the battery needs to be charged once when 70-80% of the electricity is used. The so-called full charge means waiting. After changing the lamp, it can be charged for about 2 hours to ensure that the battery is fully charged and reaches the best mileage. Generally, there is a deep discharge in about two months, that is, it can be recharged with empty to achieve the phenomenon of lead precipitation and improve the battery’s performance. Capacity, the most feared is that electric vehicle batteries are often used when they are empty or the lights are not changed when they are charged. They should be fully charged once if they are not used for about 20 days for a long time.
7. Parking environment
Under normal circumstances, the battery of an electric car is with the car. The quality of the parking environment also has a certain impact on the battery. The electric car should be kept as ventilated and dry as possible. Because the humid environment will cause electric vehicle battery leakage, so as to shorten the battery life.
8. Charger maintenance
When it comes to charging electric vehicles, the first thing to use is electric vehicle chargers. Protecting the charger is a very important step. Now the cost of electric vehicles is relatively low, and the shock-proof performance of the charger is not very good. Many people like to put the charger in the trunk or basket of the electric vehicle. In fact, this behavior is very bad. Because the electric vehicle charger will cause the internal electrical potentiometer to drift after long-term vibration, making the charging parameters become abnormal, the life of the battery will be shortened when the charging time of such a charger is long, and the charger needs to be charged. Ensure good ventilation to ensure good heat dissipation.
9. Pay attention to frequent maintenance
Many electric car dealers will provide free after-sales maintenance services, which can be regularly inspected and maintained. For example, the lack of battery electrolyzed water can only be discovered during maintenance. Measures such as timely water replenishment are also very important for battery maintenance.
10. Charge every day
Many people have a certain misunderstanding about how long electric vehicles should be charged, thinking that they should wait until the electric vehicle battery is completely used up before charging. In fact, this is also wrong. The current electric vehicle batteries generally use lead-acid batteries, which have not very strong memory capabilities, but often discharged batteries will have a greater impact on the battery. Daily charging makes the battery power in a shallow cycle state to make the battery life of electric vehicles longer.
11. Regular deep discharge
As mentioned earlier, electric vehicles should be charged every day as much as possible. However, reasonable regular deep discharge is also beneficial to "activate" the battery. Generally one to two months deep discharge is the most reasonable. The specific method is to charge the electric bike when it is under-voltage indicated. Note that after riding to undervoltage, the electric bike will recover part of its power after a period of time. Do not ride it again at this time, otherwise the battery will be very damaged.
12. Good cycling habits
I talked about the precautions for charging electric vehicles, now I will talk about the issues that need to be paid attention to when riding a bicycle. There is a principle to master when riding a bike, start slowly and stop slowly. Specifically, the feed flow should be slow when starting and try to avoid sudden braking. Because the electric load is the largest when the electric vehicle starts and brakes suddenly, frequent unstable current will reduce the life of the electric vehicle battery.
