Class 1 dealer-repair premiums for EVs aged 2–5 years start at THB 16,900 per year, depending on the car model
Key point: see how the battery cover, sum insured and premium change in years 2 and 3 before you hit renew
The Class 1 insurance that came with your EV is about to expire, and the renewal notice arrives with a higher premium than you expected, while friends with the same model say another insurer is several thousand baht cheaper
Before you renew your EV insurance for years 2–3, the premium is not the only thing that changes. On some plans the battery reimbursement rate and the sum insured also go down. What should you check?
What changes when you renew EV insurance in years 2–3?
Short answer: When you renew EV insurance in years 2–3, some plans pay less for the battery as it ages, from 100% in year 1 to 90% and then 80%. The sum insured falls with the car's age because it is set at 80% of the car's value, while on some plans the premium stays the same every year for cars aged 2–5 years. EV owners whose first-year policy is about to expire should compare battery terms before comparing premiums. Class 1 dealer-repair premiums start at THB 16,900 per year (data as of 11 Oct 2026). The actual premium depends on the car model, the sum insured and the named drivers.
How does year 1 differ from years 2–3?
| Topic | Year 1 (new car) | Years 2–3 |
|---|---|---|
| Battery reimbursement rate (plans that reduce with battery age) | 100% | 90% (battery aged over 1–2 years) 80% (battery aged over 2–3 years) |
| Sum insured | 80% of the new car's price | 80% of the car's value at renewal, falling every year |
| Premium table | New-car table, from THB 18,900 per year | Table for cars aged 2–5 years, from THB 16,900 per year |
| Car models accepted | As in the new-car table | May differ from year 1; some models are not in the table for cars aged 2–5 years |
Both tables show the starting premium for the model with the lowest premium. Data as of 11 Oct 2026, private use.
Full battery reimbursement table for plans that reduce with battery age (data as of 4 Aug 2026)
| Battery age | Reimbursement rate |
|---|---|
| Up to 1 year | 100% |
| Over 1–2 years | 90% |
| Over 2–3 years | 80% |
| Over 3–4 years | 70% |
| Over 4–5 years | 60% |
| Over 5 years | 50% |
Not every plan has this table. Some plans do not reduce the rate with age, and some insurers let you buy extra battery cover at a higher premium. A simple rule: when you renew in year 2, first ask which type the plan uses.
Roughly how much is the premium when renewing EV insurance in years 2–3?
| Plan | Starting premium per year | Data as of |
|---|---|---|
| Class 1 dealer repair, car aged 2–5 years | THB 16,900 | 11 Oct 2026 |
| Class 1 dealer repair, car aged 1–5 years (battery cover reduces with age) | THB 17,000.16 | 4 Aug 2026 |
| Class 2+ dealer repair for EVs | THB 13,000 | 5 Sep 2026 |
Every figure is a starting premium. The actual premium depends on the car model, sum insured, use, claims history and named drivers. Some plans do not yet include compulsory motor insurance (CMI). Pay the amount shown on your quotation.
A worked example to illustrate
How different is the payout for battery damage in year 2 and year 3?
Suppose the battery is worth THB 400,000 and must be replaced after damage from a covered accident (hypothetical figures), on a plan that reduces with battery age
- Battery aged over 1–2 years: 400,000 × 90% = THB 360,000. The car owner pays THB 40,000 themselves
- Battery aged over 2–3 years: 400,000 × 80% = THB 320,000. The car owner pays THB 80,000 themselves
How much does the sum insured fall?
From the Class 1 table for cars aged 2–5 years: BYD DOLPHIN (up to 175 hp), 3 years old, current car value THB 375,000 (hypothetical figure)
- Sum insured = 375,000 × 80% = THB 300,000
- Starting premium THB 28,400 per year, the same as when the car was 2 years old, because this plan charges the same premium every year for cars aged 2–5 years
- If the car is stolen or written off, you receive the sum insured of THB 300,000
This is an illustration only. The actual payout depends on the insurer's claims assessment under the policy conditions. A simple rule: in year 3 the same plan may pay less even though the premium stays the same.
Who should check this before renewing?
- EV owners whose showroom-supplied insurance is about to expire and who must renew it themselves for the first time
- People with quotations from several insurers whose premiums differ by thousands of baht
- People who drive every day or long distances, who face a higher risk of underbody impacts than occasional drivers
- People who plan to keep the car for several more years, because on some plans the battery reimbursement rate keeps falling every year
Who should not renew on a low premium alone?
- Cars whose battery is entering year 3. On plans that reduce with battery age, the payout drops to 80%, and the difference you pay yourself may exceed the premium saved over several years combined
- Car models not in the table for cars aged 2–5 years, such as Hyundai, Kia and Nissan Leaf, are not in the table of one Class 1 plan we checked. A cheap quotation may be for a plan that does not accept that car.
- People who do not want to name their drivers. The Class 1 EV plan we checked requires 1–5 named drivers and the submission of driving-behaviour data
- People who expect the insurance to pay when the battery degrades with age. The plan we checked states that it does not cover deterioration or reduced capacity
- People who made a claim in year 1. The renewal premium may rise. Compare several insurers on the same battery terms, not just the premium amount
Limits to check before you decide
- The battery reimbursement rate falls every year on plans that reduce with battery age, by 10% a year down to 50% once the battery is over 5 years old
- The sum insured falls with the car's value. It is set at 80% of the car's value. Repair costs or value above the sum insured are paid by the car owner
- The premium does not fall with the sum insured. One Class 1 plan for cars aged 2–5 years charges the same premium every year in this period
- Class 2+ plans have no separate battery limit. The battery shares the sum insured with the car and is covered only for damage from collision with a land vehicle or fire
- Wall-mounted chargers: at least one plan states they are not covered
- Terms can change. Premiums and battery terms change as the insurer announces. Rely on the wording of the latest policy and quotation
Questions to ask before renewing
- What percentage of the battery is reimbursed this year, and what will it be next year?
- Is battery age counted from the car's registration date or from the date the battery was installed?
- What is the sum insured this year, and how much has it fallen since year 1?
- Is this car model in the insurer's accepted table?
- If you switch insurers, are the battery terms better or worse than on your current policy?
Ask them to point to the wording in the policy that answers these questions; do not accept a verbal answer alone. If you are unsure about dealer repair versus garage repair, read Network garage vs non-network garage vs dealer repair: which should you choose?
What do I need to send if I want the battery terms compared at renewal?
Send just 2 things
- A photo of the registration book's front page
- Your renewal notice, or the front page of your current policy

Frequently asked questions
If I renew with the same insurer, will the battery terms be the same as in year 1?
Not necessarily. If the plan uses a table that reduces with battery age, the reimbursement rate falls with the battery's age even if you renew with the same insurer. Check the renewed policy.
Can I switch insurers in year 2?
Yes, if the car model is in the new insurer's accepted table and passes underwriting. See an example of a plan with premiums by model at EV insurance, dealer repair, cars aged 2–5 years
Is the premium lower for a 3-year-old car than for a 2-year-old car?
Not always. One Class 1 plan we checked charges the same premium every year for cars aged 2–5 years. What goes down is the sum insured.
If I made a claim in year 1, can I renew in year 2?
Yes, but the premium may rise and depends on the insurer's assessment. Tell us your claims history when you ask for a quotation and we will compare several insurers. Read more at Does the premium go up after a claim?
If the Class 1 premium in year 2 is over budget, can I drop to Class 2+?
Yes. The Class 2+ plan for EVs starts at THB 13,000 per year (data as of 5 Sep 2026), but it covers the car only for collisions with land vehicles, fire and theft. Hitting a pole or wall is not covered for the car. If the car is still being paid off, first check whether your finance contract requires Class 1.
Who decides whether the battery is repaired or replaced as a whole?
Assessing the claim, including whether to repair or replace parts and how much is paid, is the underwriting insurer's decision under the policy conditions. Prakanthai.com, as the broker, helps coordinate and follow up.
