Do you need to change the battery when the range of electric vehicles decreases in winter?
As of December 5th, 10 cities in Jiangsu have entered the winter in the meteorological sense, the weather is going to gradually turn colder, many people find that their electric bicycles, the mileage is much less, is there a problem with the battery, should the battery be replaced?
The quality inspector said that it is normal for the battery of the electric bicycle to be less durable in winter than in summer, and the battery may be reduced due to the impact of low temperature. Citizens can first check whether the battery has reached the end of its useful life. Generally speaking, the normal battery life of an electric bike is about 2-3 years. If it has been used for more than two years, and the charging time is significantly shortened, the range is not high in the summer, and the range is significantly reduced in the winter, these situations indicate that the battery is almost at the end of its useful life.
Wang Jian, a testing engineer at the National Smart Grid Quality Inspection Center of the Nanjing Quality Inspection Institute, said that due to the low temperature in winter, the electric bicycle battery is greatly affected by the temperature, the activity will be reduced, and the storage capacity will be reduced, which will affect the mileage. In addition, the temperature decreases in winter, the tire pressure decreases, the emergency start and stop, and overload, these factors will lead to an increase in the discharge current of the battery, affect the power consumption of the battery, and accelerate the power consumption.
How can you make the electric bicycle run farther and safer in winter? The quality inspector said that the temperature is too low to make the battery not fully charged, resulting in battery power loss. If conditions permit, it is recommended to choose a professional charging place with a relatively high temperature, and do not charge at home or in stairs, aisles and other places to prevent fire and other dangerous situations. In addition, the battery drops quickly in winter, and if the power is not good, riding at a loss of power may lead to over-discharge, which can cause fatal damage to the battery.
Wang Jian said, "Everyone will always worry that the battery is not fully charged, or even full and placed for a long time, and the actual battery will be stored for a long time will cause the battery to lose power, causing the commonly known 'starvation' state." The battery cannot be charged next time due to damage caused by power loss, or the battery life is affected, so everyone should ensure that the electric bicycle is charged once a month if it is not used often. ”
In addition, in the case of slippery road surfaces in winter, an appropriate reduction in driving speed can reduce the frequency of braking and acceleration, thereby reducing the load on the battery. Try to maintain a smooth ride and avoid actions such as sudden braking and sudden acceleration to slow down the drain on battery power.
