Alternator charge control (Wakespeed / smart regulator)

If your build uses a smart alternator regulator (e.g. Wakespeed), you can automate when alternator charging is allowed and how aggressively it charges — based on ignition state, battery SOC, temperature, and “quiet” modes.

How to install

  • A smart alternator regulator (e.g. Wakespeed) and a way to control/observe it (CAN, serial, GPIO/relay, or a bridge device)
  • An ignition / engine-running signal

How it works

  • Provide safe, mode-aware enable/disable of alternator charging
  • Surface key signals (charging enabled, target voltage/current, faults)

Common automations (ideas)

  • When ignition turns on and charging is allowed, enable alternator charging
  • Reduce alternator charge targets when batteries are cold/hot
  • Disable alternator charging in “Stealth” or “Protect battery” situations
