Battery maintenance tips for electric vehicles in winter are worth collecting!

pxid 2021-01-27 152 times

Winter is here, and the weather becomes colder. Many car owners find that the battery capacity of electric vehicles has shrunk a lot, or become difficult to charge, or even unable to start. A full charge is obviously far worse than summer in terms of battery life. Why?

In fact, it can be said that the maintenance of electric vehicle batteries is often talked about. In summer, it is necessary to prevent battery spontaneous combustion, and in winter, it is afraid of battery spontaneous combustion and battery durability. Today, the editor of PXID Industrial Design Company will share with you some battery maintenance skills summarized in the actual use process, hoping to give you some references for those who own electric vehicles in the cold winter.

When the red undervoltage indicator light on the dashboard glows, it indicates that the battery has entered the hungry zone and should be charged in time. The number of charging cycles of the battery is fixed, the number of cycles of charging and discharging lead-acid batteries is 300-400 times, and that of lithium batteries is more than 500 times. Therefore, from 0-100% full charge, one charge-discharge cycle is used up, so do not perform frequent charge and discharge, but charge when the battery is about 30% remaining. Each charge time should be 8- 12 hours, this can slow down the decline in battery capacity.

When the electric bicycle starts, it should accelerate slowly, especially in cold winter, the battery starts slowly, and it should be started slowly; at the same time, try to avoid sudden acceleration or sudden braking during riding, such as uphill, bridge, headwind or When overweight driving, pedal assistance must be used, and the driving must not be overloaded or continue driving when the battery is running low to avoid high-current discharge of the battery, so as to extend the life of the battery and motor, and to avoid burning electrical components.

When the ambient temperature is higher than 40°C or lower than -10°C, the battery life will be shortened. Therefore, when the temperature is low in winter, the battery should be stored indoors and charged indoors. After the battery is fully charged, it should be charged for another 2 hours. At an ambient temperature of -10°C, the battery's power can only be released 60%. Therefore, the mileage of a full charge in winter is much less than that of a full charge in summer.

The battery is a consumable, and the battery life is limited. If your electric car has experienced "violent" riding in the summer, it is very necessary for you to check the remaining battery power of the vehicle. If the battery is worn out, it is recommended that the user replace it with a new battery after entering the winter. When buying a new battery, also bring the standard charger with the battery. Try to charge one battery at a time. It is best not to mix the chargers. It is easy to burn the battery of the electric vehicle if you use the charger from a brand-name manufacturer.

Electric vehicles are idle in winter, but the battery cannot be idle. Lead-acid batteries are especially afraid of losing electricity to discharge. Lead-acid batteries that lose electricity may be permanently damaged if they are left for 3-7 days. Therefore, the batteries should be charged as soon as possible after use. For batteries that have not been used for a long time, the batteries should be recharged at regular intervals to compensate for the self-discharge power loss during battery storage.

Finally, the editor kindly reminds everyone: It is normal for the low temperature in winter to reduce the storage capacity of lead-acid batteries, and it has nothing to do with the quality of the batteries. Users should not blindly replace batteries. There are other common factors for electric vehicles not running far, not necessarily all battery problems. Customers should take the actual situation as the standard and find out the battery that really has problems in time!
