　　Will the range of electric vehicle batteries be reduced when the weather is cold?

　　After the turn of autumn, the weather will quickly become colder and colder, and people's spirits will become listless when exposed to the cold. The same goes for electric bicycles. Some car buyers said that they can usually ride an electric bicycle for 40 to 50 kilometers. It was freezing cold, and the battery ran out after running for 20 to 30 kilometers. I also tried the electric bicycle pedals that experts often say can help me pedal home in an emergency, but I gave up after pedaling for five minutes. I was very tired. , so I pushed the battery car home. The master of the maintenance shop said: This situation is normal. It does not mean that the battery is broken, and there is no need to replace the battery. Usually, these three points can be easily solved by yourself;

　　First of all, electric bikes do not need to be placed outdoors when not being ridden.

　　Whether it is a lead-acid battery or a lithium battery, everyone is actually worried about the cold. At ultra-low temperatures, the battery capacity will decrease and the multiple performance will decrease. If the temperature is less than minus 10 degrees, the lithium battery electrolyte will condense and will not be charged or discharged. If it is used for a long time At ultra-low temperatures, the rechargeable battery may be damaged immediately;

　　Therefore, once the cold season arrives, our battery cars cannot be piled up casually. They should choose a parking area with a higher room temperature. If there is really no room with a lower room temperature, you can choose to take the rechargeable batteries into the room separately;

　　The second is to master the battery charging time.

　　When encountering cold and windy conditions, the rechargeable battery will become more and more difficult to "serve". When charging the battery, we should try our best to charge the battery in an area where the temperature is not too low, otherwise it will be difficult to fully charge the battery. Leave a little more power in winter than in summer, otherwise if there is no power in cold weather, it will easily cause the battery to become more fragile;

　　Moreover, the master reminds car buyers that the charging time will not be as long as possible. Many ordinary chargers do not have the function of automatically turning off the power. When you see the charging indicator light changes, you need to manually turn off the power immediately;

　　3. Please don’t use too much force when turning the door handle while riding a bicycle.

　　Many car buyers drive more vigorously, accelerating and braking quickly. This behavior will first pose certain traffic safety risks, and the sudden increase and decrease of current will affect the performance of the battery and shorten its service life. In addition to Pay attention when accelerating at ordinary times. There is also a situation where when going uphill, many people twist it to the end because they are afraid that they will not be able to climb up. This is a behavior that is very harmful to the battery. The correct approach should be to twist the battery door lightly and rely on the low gear. To increase the torque, if it still cannot be increased, you can use pedals or manual assistance installed by experts, which is neither dangerous nor damaging to the battery;

　　Finally, the master reminds us that it is normal for the battery life to decrease when the weather is cold. There is no need to be deceived by the store into replacing the battery or adding water. We only need to maintain the battery during the cold season and avoid the impact of the temperature on the battery. reduce to a minimum;
