Abstrakt

In comparison to conventional fossil fuel powered cars, electric vehicle (EV) technology faces a substantial challenge in terms of driving range, especially when the climate control system relies entirely on the onboard electric battery. The conventional heating system using resistive heaters and cooling via vapor compression can result in a significant reduction in mileage. Therefore, we report an adsorption-based advanced thermal battery (ATB) capable of delivering both heating and cooling for electric vehicles, which operates with minimal use of the on-board electric battery bank. While the traditional adsorption based climate control systems are often bulky and heavy, ATB is compact and light-weight with higher energy and power densities compared to current adsorption based systems. A theoretical analysis is carried out to determine the overall performance of the ATB-based climate control in terms of energy density as a function of the ATB design, adsorption properties and operating conditions. Using zeolite 13X-water, the theoretical analysis shows that the ATB can provide heating and cooling densities in excess of 0.4 and 0.2 kWh/kg.
