Description

Integrated controller and energy storage thermal management unit

technical field

The utility model relates to the technical field of controllers, in particular to an integrated controller and an energy storage thermal management unit.

Background technique

The controller is an important part of the energy storage thermal management unit, which is used for accurate measurement and monitoring of the coolant temperature.
