A method of minimizing C-Rate fluctuations with an electrically powered accessory (EPA) is disclosed. The EPA is configured to be used with at least one of a vehicle, a trailer, and a transport container that has a first controller. The EPA has a second controller. The method includes determining, by the first controller, a first C-Rate of a Rechargeable Energy Storage System (RESS). Also, the method includes comparing the first C-Rate to a first predetermined threshold. The method also includes when the first C-Rate exceeds the first predetermined threshold, the first controller sending a first request to the second controller to adjust a load of the EPA. The method further includes the second controller determining a first operational mode of the EPA based on the first request. Also the method includes when the first operational mode of the EPA allows a load change, the second controller adjusting the load of the EPA.
