1, check whether the product logo is complete. Including the name of the manufacturer, product specifications and models, date of manufacture, and trademarks; Check whether the internal and external signs are consistent, especially check whether the product body has eye-catching signs, and pay attention to whether the processing date is in the near future.
2. Pay attention to the appearance of the battery. Check whether there are traces of deformation, cracks, scratches and leakage. Battery terminals should be clean, no rust, marks should be clear.
3. Pay attention to the rated capacity of electric vehicle battery products. The larger the rated capacity of the battery label, the longer the battery discharge time, it is better not to buy the battery without the rated label, but pay attention to whether it is special for electric vehicles, if there are more than one capacity label, the rated capacity shall be the criterion.
4, the purchase of well-known companies, large companies brand batteries. Batteries are generally supplied by professional battery factories. The quality of batteries processed by different brands and manufacturers is different, and the price is also high and low. Well-known, large scale companies, strong technology, good after-sales service, battery quality is guaranteed.
5, choose and battery matching, with automatic control of the intelligent charger. The appropriate charger can automatically adjust the charging size and time, which is conducive to prolonging the service life of the battery.
Use common sense
1. When in use, it is best to use human assistance to start the electric car when it starts up and uphill against the wind. When the simple electric car starts up, uphill and riding against the wind in the strong wind, it should use foot power to reduce the battery load and prolong its life; Luxury electric cars should start slowly, rather than rapidly accelerating. When going downhill, the electric car can be released from the handlebar. When the power is low, ride at a slower speed; No matter when, should not be under the state of electric riding.
2, when using an electric bicycle, do not overload. The design of the general electric bicycle load is 75kg, that is, a single ride, the overload will cause the battery for a long time of high current discharge, thereby damaging the battery, which is an important reason for the battery life shortened.
3, it should be noted that the capacity of the battery is changed with time and the environment. Generally speaking, the battery capacity will gradually decrease with the increase of use times. In the case of low temperature, the battery capacity will also be reduced, to be restored when the temperature rises.
4. Master the correct charging method. The ambient temperature of the battery should be between 0 ~ 40℃, and the charging should be carried out at room temperature. Pay attention to the charging state and normal charging time of the charger to prevent undercharging or overcharging of the battery. When abnormal charging is found, consult professionals in time so as not to damage the battery. Recharge it in time after use. It is better to charge it every day. For example, it is better to charge it in time when driving more than 20 kilometers. Long-term use, to replenish the battery on time.
