v0.2.1

For the 2022 Ioniq 5 (US), Gen5W software 260507, with NEMESIS and HMG Leafia Plus v1.0.5 installed first. Changes since v0.1.1.

New

• Real usable capacity, learned from the BMS instead of the new-car 77.4 kWh.
• Cold-weather model driven by the live outside temperature.
• More realistic charge times, including the slow last 10–20 %. (Earlier versions sent the charge tables in a form Maps misread, so 100 % looked much faster than it is.)
• Automatic battery preconditioning when the next stop is a charger over 50 kW within an hour. Turn it off with the car's battery conditioning setting.
• EV logs whenever the car is on, driving or charging: battery energy and power, speed, temperatures, climate, charging, Maps' route plan. Copied to any USB drive with an egmp-aa-ev-logs folder, with a pop-up when done. Share them through an EV log issue to help improve the model Note: these logs are generated in a way to be useful while still being anonymous ish (no location, no absolute time/elevation, etc).

Install

Copy the zip's contents to an empty FAT32/exFAT drive, plug it in with the car on, and tap Yes. It upgrades earlier versions in place and restarts the head unit; the first Android Auto start afterwards can take an extra minute.

Known issues

• Charging times seem suspect still: 13 mins 21-79%?? unlikely... possibly related to how we generate dynamic on-the-fly tables from actual battery capacity.
• The drive-mode column in the logs stays empty.
• Only this car and software version for now.
