The main content of today's lecture is the maintenance of electric vehicle lithium battery. Electric vehicle, like fuel car, needs maintenance in daily life. Electric vehicle lithium battery is like fuel tank, it is the power source of vehicle driving. Under the daily correct maintenance, can guarantee the power battery durable.
Tip 1: no power loss during storage
Power battery is strictly forbidden to be in the state of power loss during storage. The state of power loss means that the battery is not recharged in time after use.
It is easy to occur sulfate salinization when discharge in the state of deficiency, and the crystal of lead sulfate adheres to the electrode plate, which blocks the electric ion channel, resulting in insufficient charge and the decrease of the battery capacity. The longer the idle time of the deficient state is, the longer the battery capacity is. The more the battery is damaged.
Therefore, the battery should be replenished once a month when it is idle, so that it can keep the battery healthy.
Tip 2: Periodic testing
In the course of use, if the electric vehicle's continued mileage in a short period of time suddenly dropped more than ten kilometers, it is very likely that at least one battery in the battery grid, plate softening. Short circuit phenomena, such as the abscission of active materials from the plate.
At this time, the professional battery repair mechanism should be inspected, repaired or equipped in time, so that the battery life can be relatively extended, and the maximum cost savings.
Tip 3: Avoid large current discharges
Electric vehicles in the start, manned, uphill, try to avoid stepping acceleration, instantaneous high current discharge will have an impact on battery life.
Tip 4: master charging time
Charge at night, the average time is about 8 hours, try to charge the electricity at a time, avoid overcharge and undercharge.
If the discharge is shallow (the mileage is very short after charging, the battery will be filled quickly, and the recharge will overcharge, which will cause the battery to heat up and reduce the battery life.
Therefore, the battery with discharge depth of 60-70% charge is the best, the actual use can be converted into driving mileage, according to the actual situation of the necessary charge to avoid harmful charging.
