Introduction
Electric vehicle (EV) batteries are among the most costly components in an EV. Proper care can extend battery lifespan, while poor driving and charging habits may lead to early degradation or expensive repairs.
Key factors affecting EV batteries include:
- Driving habits – frequent hard acceleration, high-speed driving, or carrying heavy loads can degrade battery performance.
- Charging habits – overcharging, repeated fast-charging, or letting the battery drop to very low levels can shorten battery life.
Understanding these factors allows EV owners to save money and maintain optimal performance.
Common EV Battery Risks
| Risk | Cause | Impact | Prevention |
| Overcharging | Charging to 100% too often | Reduces battery lifespan | Charge to 80–90% for daily use |
| Deep Discharge | Letting battery reach 0% | Stress and potential damage | Recharge before 20% |
| Aggressive Driving | Hard acceleration or high speeds | Accelerates battery degradation | Drive smoothly and maintain steady speeds |
| Excessive Fast Charging | Frequent use of high-power chargers | Increases wear and heat | Use slow charging when possible |
Tips for EV Owners
- Avoid frequent full charges to 100% unless necessary for long trips.
- Recharge before the battery is fully drained.
- Drive smoothly; avoid harsh acceleration or braking.
- Prefer slow charging when possible to reduce stress on the battery.
Conclusion
Following good driving and charging habits is essential for prolonging EV battery life and avoiding costly replacements. By adopting these practices, Malaysian EV owners can maximize battery performance and save on maintenance costs.
