10 Practical Tips for Extending the Battery Life of New Energy Vehicles

The maintenance of new energy batteries has multiple benefits, mainly including extending battery life, improving vehicle performance, and ensuring driving safety. ‌ Maintenance can improve the overall performance of the vehicle. Good battery maintenance can ensure the stability and strength of power output, especially in driving scenarios such as acceleration and overtaking.

 

Optimization of charging habits

 

1. Avoid full charging/deep discharging

-Daily use: Maintain the battery level within the range of 20% to 80%, avoiding long-term storage at full charge (100%) or low charge (<10%).

-Long distance demand: Use the battery as soon as it is fully charged to reduce the high battery idle time.

 

2. Reduce fast charging frequency

-Fast charging (DC charging) generates more heat due to high current, accelerating battery aging. Prioritize slow charging (AC charging) for daily use, and fast charging is only for emergency purposes.

 

3. Charge as needed to avoid low-temperature charging

-When the temperature is low (<0 ℃), the battery activity decreases. Before charging, the battery can be preheated (some models support pre charging preheating).

-After being exposed to high temperatures in summer, let the vehicle cool down before charging.

 

 

Use environmental management

 

1. Temperature control

-Extreme parking avoidance: Avoid prolonged parking in environments above 40 ℃ or below -20 ℃, as high temperatures accelerate electrolyte decomposition and low temperatures lead to lithium precipitation.

-Charging environment: Prioritize charging in underground garages or shady places.

 

2. Rest intervals during long-distance driving

-When driving continuously at high speeds, the battery continues to work under high load, stopping and resting for 10 minutes every 2 hours to help dissipate heat.

 

 

Battery maintenance techniques

 

1. Regularly calibrate the battery

-Perform deep charging and discharging every 3 months (charge to 100% when the battery level is below 10%), and calibrate the BMS (battery management system) battery level display accuracy.

 

2. Long term parking strategy

-If the vehicle is idle for more than 15 days, keep the battery level at 50%~60% and disconnect the negative terminal of the small battery (not a high-voltage battery) to prevent static power consumption damage.

 

3. Pay attention to battery health

-Regularly check the state of health (SOH) of the battery through the car's infotainment system or 4S store, and consider replacing it if it is below 70%.

 

 

Adjustment of driving behavior

 

1. Smooth driving

-Reduce sudden acceleration and braking to avoid damage to battery cells caused by sudden high current discharge.

 

2. Reasonable use of energy recovery

-Activate the strong energy recovery mode, recover electrical energy through coasting deceleration, and reduce mechanical braking and battery load.

 

 

Manufacturer's suggestions and upgrades

 

-Firmware update: Upgrade the vehicle BMS system in a timely manner, and the manufacturer will optimize the charging and discharging strategy through algorithms.

-Original accessories: Use brand certified charging stations to avoid voltage instability caused by third-party inferior equipment.

 

Summary:

Battery life=gentle charging and discharging (20%~80%)+temperature management+reduced fast charging+regular maintenance.

By following this procedure, most ternary lithium batteries can be used stably for 8-10 years, and lithium iron phosphate batteries can last for more than 10 years!
