3 Main Reasons You Might Need a New EV Battery
Many people think that normal degradation over time is the main culprit. In reality, "accidents" are the primary reason car owners have to shell out big money:
- Undercarriage Damage: Most EV batteries are installed under the vehicle. If you drive over a deep pothole, scrape a footpath, or hit debris that damages the battery case structure, service centers will usually recommend replacing the entire pack to prevent fire risks.
- Flooding Past Safe Limits: Even though EVs are water-resistant to IP67 standards, driving through deep water for extended periods or soaking in floods until water breaches the high-voltage system will cause a short circuit and immediate battery failure.
- Degradation Over Time: All batteries have a lifespan. With prolonged use, the charge retention efficiency decreases (most are covered by a service center warranty for 8 years or 160,000 km).

Besides having insurance to handle accidents, taking care of your battery daily will help save money in your pocket:
- Maintain battery level between 20% - 80%: Avoid letting the battery drain completely (0%), and there's no need to charge to 100% every day (except for LFP batteries, where automakers recommend a 100% charge once a week).
- Prefer AC (Home Charging) over DC (Fast Charging): Frequent DC fast charging generates accumulated heat and degrades battery cells faster than normal.
- Park in the Shade: Thailand's extreme heat directly impacts the battery's cooling system. Parking in the sun for long periods forces the battery to work harder.

If the battery degrades naturally, the service center will cover it (under Warranty conditions). But what if the battery is damaged in an accident? The service center won't replace it for free! This is where Class 1 EV Insurance plays a crucial role.

Frequently Asked Questions (FAQ) About EV Battery Replacement
Does Class 1 insurance cover the EV battery 100%?
According to new OIC regulations, most EV insurance covers up to 90% (or based on a depreciation table). PrakanEV's EV Plans specifically select those offering a maximum 90% coverage throughout the policy term to minimize the customer's out-of-pocket expenses.
Can I claim insurance if I scrape a footpath and scratch the battery?
Yes, you can! If the battery is damaged due to an accident (impact, scraping), Class 1 insurance will cover the repair or replacement of a new battery. We recommend reporting the claim immediately for safety reasons.
Will auto insurance cover a battery that degrades over time?
Auto insurance will not cover degradation over time. However, this is covered by the quality warranty provided by that brand's service center instead (usually 8 years or 160,000 km).
