## BZ-Battery Description
BZ-Battery reads the high-voltage battery in a Toyota bZ4X and shows you what the car keeps to itself, on your phone and on your CarPlay screen.

You need a Bluetooth LE OBD adapter, plugged into the port under the dash. It is tested with an OBDLink CX; vLinker and Veepeak should work too. The cheapest "ELM327 mini" clones often can't read this car. The adapter is not included.

What you get:

• Charge, power and current, live
• Every cell voltage, with the weakest one marked
• All pack temperature sensors
• Battery health, as the car itself reports it
• Measured pack capacity, tracked over months
• The 12 V battery's voltage
• Every drive and charge kept, with the energy it used
• Five dashboards. Pick the one you like.
• CarPlay: charge, power, cells, temperature and 12 V on the car's screen

It only reads. The app cannot change a setting, clear a fault, or write anything to the car at all. That is enforced in the app.

No account, no ads, no tracking. Your readings, history and settings stay on your phone. What the app does send is anonymous and never identifies you or your car: the car model you picked, a short report of how each connection went, and battery-health figures for a study of how these packs age. You can switch the reports and the study off in Settings. Drive summaries are sent only if you turn that on.

No car to hand? There is a demo mode built in, so you can look at every screen before you plug anything in.

An independent app. Not made by, affiliated with, or endorsed by Toyota, Subaru or Lexus.
