Because electric vehicles are convenient and eco-friendly, they are loved by consumers. The battery is the power source of an e-bike, so what factors affect an electric vehicle battery?

1. Lower temperature

(1) Battery temperature effect: the colder the weather, the lower the battery capacity. For example, at 0°C the capacity is only 85%. Chemical reactions take place during charging and discharging; the lower the temperature, the lower the activity of the active material, the higher the internal resistance and viscosity of the electrolyte, and the harder it is for ions to diffuse, so charging and discharging become difficult and the driving range is affected. After winter, when the weather warms up, the range will recover. This is a normal phenomenon.

(2) Whole-vehicle efficiency: the colder the weather, the lower the overall efficiency. For example, at 0°C the vehicle efficiency drops by 5%. During riding, the battery converts chemical energy into electrical energy, the motor converts electrical energy into mechanical energy, and the transmission mechanism then converts mechanical energy into kinetic energy to set the vehicle in motion. The conversion efficiency of the motor and transmission is affected by the ambient temperature. This is a normal phenomenon.

(3) Vehicle load: the colder it is, the more clothes consumers wear, so the overall load is relatively heavier and more power is consumed. This is an unavoidable phenomenon.

2. Battery aging

3. Improper charging and discharging: improper charging and discharging make the battery age faster.

4. Overloading: overloading speeds up power consumption and reduces the driving range.

5. Low tire pressure: if the tire pressure is too low, the resistance to the e-bike moving forward increases, wasting its limited power and reducing the range.

There are many factors that affect an electric vehicle battery; only some common problems are listed here. We hope they are helpful.
