r/BZ4X

​

Purely by chance, I ended up testing the car's battery buffer at "zero". To be specific, this was the bZ4X Touring (bZ Woodland) 4WD version with 18" summer tyres, so a 74.7 kWh battery with 71 kWh usable.

The reason was simple: driving out to the countryside, I didn't fully charge the battery beforehand because I planned to try out Ionity fast charger. However, by setting it as the destination in the onboard nav with a relatively empty battery, the car decided to prepare for fast charging, and the +10 kW heating created a situation where, 15 km before Ionity, the car showed 0% and 0 km. Luckily, there was roadworks there, so I drove 70 km/h in a 70 km/h zone without any worries. Carscanner reported that there was actually 5% battery left, and it seemed there shouldn't be a problem. 5 km before the Ionity, there was only 2% left according to the BMS, and I could no longer drive over 65 km/h. Again, fortunately, there was road repair with constant 70-50-70 speed limits. 2 km before charger the maximum speed dropped to 50 km/h, and with that, I managed to roll up to the Ionity charger. When plugging in, the BMS showed 1.176% of juice left in the battery.

Charging was hassle-free: 40.93 kWh was pushed into the battery in 17 minutes.

It was exciting, but I won't do it again.

Hi everyone 👋

A new update for BZ Battery is out - and the biggest news is that the app now supports **CarPlay** 🚗

It required a special approval from Apple, but it's finally in place. That means you can see battery, power consumption, temperature and cell voltages right on the car's screen while you drive.

As always, I'm happy to take criticism/praise and feature requests through the mail in the app.

Best regards, Andreas.
