Features of care for lithium-ion batteries at extreme temperatures

Introduction

Lithium-ion batteries are widely used in electric vehicles today due to their high energy intensity, light weight and ability to charge quickly. However, the operation of such batteries in extremely high or low temperatures requires a special approach and compliance with certain rules of operation and maintenance.

Why is temperature important?2nd

The ambient temperature has a significant impact on the operation of lithium-ion batteries:

• At too low temperature, the battery capacity decreases, which leads to a reduction in mileage and operating time.
• High temperatures can accelerate battery wear, reducing its life and life.

Operation at low temperatures

How do low temperatures affect the battery?

When the temperature decreases, the chemical processes inside the lithium-ion battery slow down, which leads to a decrease in battery capacity and a decrease in the current available to power the electric motor. Moreover, in severe frosts, there is a risk of damage to the battery due to the freezing of the electrolyte.

Recommendations for operation in cold weather

1. Storage and charging at room temperature: If the motorcycle is stored in the garage for a long time in winter, it is recommended to keep it in a warm room before the trip. Charge the battery at a temperature of +18 to +25 ° C.
2. Battery heating: There are special heating devices that help maintain the optimal temperature of the battery while driving. You can also use covers or thermal insulation materials to minimize heat loss.
3. Charge level control: Try to avoid full discharge of the battery in the cold season, as this can significantly reduce its life. The optimal charge level is about 40-60%.

Operation at high temperatures

Hazards of overheating

Too high a temperature accelerates the degradation of a lithium-ion battery, reduces its efficiency and potentially increases the risk of fire. During overheating, accelerated oxidation of battery materials occurs, internal resistance increases and the total capacity decreases.

Precautions in the summer

1. Avoiding prolonged exposure to direct sunlight: Keep your motorcycle in the shade or indoors.
2. Regular check of cooling system condition: monitor the serviceability of ventilation holes and radiators of the cooling system, providing heat removal from the battery.
3. Use of protective coatings: apply a special coating on the battery body that reflects the sun's rays and protects against overheating.

Conclusion

Compliance with simple recommendations will help you maximize the life of the lithium-ion batteries of your electric motorcycle or scooter, regardless of weather conditions. It is important to remember that proper battery maintenance directly affects the safety and comfort of your trip.
