Works through Apple CarPlay
Plug the box into the original head unit's USB port and the EVSense screen appears on the car display through the car's CarPlay — wired, or wireless on tested cars.

What EVSense does
No new head unit and no wire cutting — it uses the USB port your car already uses for CarPlay.
EV Gauge
Live EV data on the car screen — battery level, power, temperature and more — read through a Vgate OBD adapter over Bluetooth (included in the box).
EV Guardian
High-voltage battery health: cell voltage spread, temperature, insulation and SOH trend, with a weekly email report. Danger-level alerts are free on every box.
How it connects
How it connects to your car
Vgate OBD adapter
Plugs into the car's OBD-II port and reads battery and electrical data — read-only.
Bluetooth
EVSense box
Processes everything in the box — danger alerts work even with no internet.
USB · CarPlay
Original car screen
The EVSense screen shows through the car's Apple CarPlay, controlled by the car's touchscreen.
Internet (Wi-Fi) is only used to check membership and send reports. Without internet, membership keeps working for 14 days.
EV Guardian
Four things worth knowing about your HV battery — early
Cell voltage spread (ΔV)
A cell drifting away from the others is often the first sign of a weak cell or poor balancing.
Battery temperature
Too hot, or uneven between sensors — while driving and during fast charging.
Insulation resistance
Falling isolation between the high-voltage system and the car body is a safety issue worth knowing early.
SOH trend
State of Health as reported by the car, tracked as a weekly trend line.
Know the limits
EV Guardian helps you monitor and get alerts; it is not a certified safety device. The car's BMS and dashboard warnings remain the primary protection. SOH is the value reported by the car, not our own measurement. Every report is not a battery health certificate.

FAQ
Questions people ask
What is EVSense?
EVSense is an Android box that plugs into your original head unit's USB port and works through the car's Apple CarPlay, adding live EV data and EV Guardian battery monitoring.
Will EVSense work with my car?
It works with cars whose head unit supports Apple CarPlay and that are on our tested list — not every car is supported.
How do I check if my BYD Dolphin battery is degrading?
Track the SOH (State of Health) value the car reports over several weeks, together with cell voltage spread and temperature — EV Guardian on the EVSense box does this for you automatically.
What do I get for free, and what does membership add?
Free: CarPlay, EV Gauge and on-screen danger alerts with sound. EV Guardian members also get every alert level with advice, history and SOH trend, the cell map and email reports.
