Cars with manual preheat not affect calibrated consumption

Feature Requests

Cars with a manual preheat function, MEB 4.x+,HMG ccNC, GM. When using OBDII live data its constantly adjusting the calibrated consumption when the battery heater activates. In the cold weather manual preheat can take over half an hour with an additional ~6kW load. The consumption from my car went from 275 (accurate) to 340 (accurate with preheat only). This is making charging stops not accurate. If ABRP could identify the heating time and power used based on cars logged battery temp and power usage, you could create a notification to turn it on, and accurately calculate arrivial with preheat.

    Agree, ABRP should detect (via ODB or other) that the car is preconditioning and use the added consumption for a ‘preconditioning consumption profile’.

    Preconditioning-aware planning is inevitable in the long term (built-in navigation already takes preconditioning into account when calculating charger arrival SOC), so it’s best to accurately gather data around preconditioning as soon as possible.
