+description: >-
+  Provides an interface for implementing DC power supply derating functionality.
+  This allows integration of hardware-specific derating logic, for example,
+  adjusting output current based on internal temperature measurements.
+
+  In the simplest case, derating is determined solely by the plug temperature,
+  as reported by the evse_board_support driver. This value is exposed here for convenience.
+
+  More advanced implementations may incorporate additional temperature sensors,
+  such as relay temperature or other relevant measurements, to enable more precise control.
+
+  Note that this is for DC output in DC charging only.
+  To derate for AC chargers (or the AC side in DC chargers), use an EnergyNode and set external_limits instead.
+cmds:
+  set_external_derating:
+    description: >-
+      Set external derating values. The provided values
+      will be merged with the existing internal capabilities of the power supply:
+      The minimum of the internal and external values will be used.
+      All values are optional, unset means no limit.
