Guidelines for Extending the Life & Optimizing the Performance of EV Batteries

Despite substantial enhancements in battery technology that have improved EV range and charging efficiency, battery lifespan and performance are still impacted by diverse factors. To maximize the durability and optimize the performance of electric vehicle batteries, this document offers a set of guidelines aimed at assisting users in implementing scientific usage and maintenance procedures.

Avoid Extreme Temperatures

Batteries functioning in high or low-temperature surroundings may undergo accelerated deterioration. It is suggested that users minimize battery utilization under extreme temperature circumstances and maintain a stable internal temperature to extend battery lifespan.

Charge Correctly

To safeguard battery well-being, users should refrain from charging the battery to 100% or discharging it to 0%. Keeping the battery charge within the range of 20% to 80% helps mitigate cycle stress and prolong battery lifespan.

Monitor Battery Health

Regularly inspect the battery's health, encompassing charging efficiency and discharge performance, to identify potential problems at an early stage. Utilizing the vehicle's Battery Management System (BMS) data can assist in maintaining optimal battery performance.

Avoid Sudden Acceleration and Braking

Smooth driving not only enhances safety but also reduces the burden on the battery. Avoid sudden acceleration and braking to minimize energy consumption and heat generation, thereby prolonging battery lifespan.

Perform Regular Maintenance

Adhere to the manufacturer's recommendations for regular battery maintenance and inspections, including performance evaluations and necessary repairs. Appropriate maintenance measures guarantee the correct operation of the battery system and optimize long-term performance.


The lifespan and performance of electric vehicle batteries are affected by numerous factors. By implementing the measures mentioned above, users can effectively extend battery life and optimize performance. Maintaining appropriate charging habits, monitoring battery health, and adopting smooth driving practices will contribute to achieving the optimal use of electric vehicles and support sustainable transportation development.
