Two tests, prices in the open. The vehicles we can test today are listed below.
Cellproof SWIFT
芯況快檢
About 5 minutes per car
NT$1,400List price
NT$1,800Launch price
A quick look at the battery's condition. We read the car's records and check for obvious faults. No capacity measurement.
- Cell balance and voltage spread
- Sensors and system status
- Fast-charge share and charging history
- A certificate and sticker you can verify online
No capacity measurement, so the certificate shows no health percentage.
Cellproof DEEP
芯況深度檢測
One night per car
NT$2,600List price
NT$3,800Launch price
A full capacity measurement. We charge to 100%, so the health on the certificate is what we measured, not the car's own estimate.
- Everything in SWIFT
- Charged to 100%, capacity measured
- The car's own figure against the measurement
- The full charge curve
You charge overnight as you normally would and we plug our logger in. There is nothing for you to do, and the car would have been charging anyway.

| State of health (SoH) and measured kWh | Not included | Included |
| The car's own figure set against the measurement | Not included | Included |
| The full charge curve and the measurement record | Not included | Included |
| Time | About 5 minutes per car | One night per car |
| How far to rely on it | The data comes straight from the car's battery system and sensors. It is dependable for finding faults. It does not measure capacity, so it cannot tell you how much energy is left. | The result is a measurement and does not depend on the car's own estimate. The certificate prints the raw values so anyone can redo the math. We have not published an accuracy figure yet. Comparison data is still being collected. |
