# Signals, attributes and actuators around the electric powertrain.
# Signals and attributes related to the traction battery in vehicles with electrical powertrain.
# For some vehicles the traction battery is referred to as the high voltage battery.
#

# It might be possible to disconnect the traction battery used by an electric powertrain.
# This is achieved by connectors, typically one for plus and one for minus.

We got some additional information internally on that connectors for power/plus and ground/minus are handled separately in at least some vehicles, to handle different use cases. A typical example is:

  • Vehicle off, no charging: Both connectors disconnected/open
  • Vehicle off, charging: Ground connector connected/closed, Power connector disconnected/open
  • Vehicle on: Both connectors connected/closed

Based on this we propose to introducing two separate boolean sensor signals.
