1. Charging habits: avoid extreme charging and discharging
Avoid over-discharging: Charge in time before the battery level is less than 20%. Deep discharge (battery level close to 0%) will accelerate battery aging. Keep the battery level at 40%-60% when parking for a long time (such as not using the car for more than 1 month).
Avoid overcharging: It is recommended to charge to 80%-90% for daily use. Long-term storage at full charge (100%) will increase battery pressure. Fully charge before long-distance travel to reduce the stay time at full charge.
Reduce the frequency of fast charging: DC fast charging (such as supercharging piles) will generate high temperature and high voltage, and frequent use may shorten the life. Daily priority is given to AC slow charging (home charging piles), and fast charging is used as an emergency supplement.
2. Temperature management: Avoid extreme environments
High temperature protection: When parking, try to choose a cool place or underground garage to avoid exposure to the sun (high temperature will accelerate the decomposition of the electrolyte). Avoid driving vigorously immediately after fast charging in summer to let the battery cool down.
Coping with low temperatures: In winter, when the temperature is low, the battery activity decreases. It is recommended to:
Preheat the battery before charging (some models support scheduled charging preheating). Charge immediately after parking (use the residual heat of the battery to improve efficiency). Battery insulation devices can be considered for long-term low temperature environments.
3. Driving and use habits
Avoid frequent and intense driving: sudden acceleration and sudden braking will cause large current discharge of the battery and increase losses. Smooth driving can reduce battery load.
Reasonable use of energy recovery: Turning on the strong kinetic energy recovery mode (such as single pedal mode) can reduce mechanical brake losses and optimize the charge and discharge cycle.
Precautions for long-term parking: Keep the power at 40%-60%, start and replenish the power every 1-2 months. Disconnect the negative pole of the small battery (to prevent the low-voltage battery from affecting the high-voltage battery due to power loss).
4. Regular maintenance and inspection
Battery health monitoring: Regularly check the battery health (such as SOC, SOH parameters) through the vehicle system or 4S shop. Pay attention to abnormal phenomena (such as a sudden drop in endurance and abnormally slow charging speed).
Keep the battery clean: Regularly check whether the heat dissipation port of the battery pack is blocked (especially after driving on muddy roads after rain). Do not exceed the manufacturer’s standard for wading depth to avoid water entering the battery compartment.
5. Other considerations
Choose original charging equipment: Poor quality charging piles may have unstable voltage and damage the battery. System upgrade: Timely update the BMS (battery management system) software pushed by the car company to optimize the charging and discharging strategy.
Warranty policy: Understand the manufacturer’s battery warranty terms (such as 8 years/150,000 kilometers) and claim for replacement when necessary.
