Thermoelectrical Management System for Stationary Outdoor Lithium-Ion Energy Storage

A low-cost and high-efficiency hybrid semi-adiabatic enclosure is proposed. The principle behind it consists in extracting generated heat using natural convection or forced air when the ambient temperature allows it. Outside of this range, for low ambient temperatures, a reduced heat exchange to the minimum optimal temperature is achieved by transforming the enclosure into a highly adiabatic system by closing the isolated air vents. When the heat generated from the batteries is not enough for the initial starting conditions, passive heating is available for temperature increase. When the outdoor temperature exceeds the upper range, a thermo-electrical cooling system is implemented. In this paper, simulation results in PSIM are shown, as well as some experimental results, validating the feasibility of the implementation.
