Investigation of cells placement distance in a staggered configuration and specific thickness of PCM in hybrid cooling TMS

The man has to find a replacement for fossil fuels because fossil fuels are coming to an end and they are not renewable in addition, the use of fossil fuels has led to global warming due to the release of greenhouse gases, and consequently increasing of earth temperature causes climates changing. One of the largest uses of fossil fuels is the road transport industry, in the cold seasons when the inversion phenomenon occurs the life of the city population is disturbed. For producing electricity Man should replace fossil fuels with wind, sun, waves and nuclear energy. To avoid using fossil fuels in vehicles, Lithium-ion batteries are the best choice for storing electrical energy. In comparison with other kinds of batteries in the market, Lithium-ion batteries have the low self-discharging rate, high energy density, and high reliability, but temperature changes affect the performance of these batteries and can reduce their life and performance so the existence of the thermal management system (TMS) for the batteries is inevitable. One of the most powerful thermal management systems for batteries is hybrid TMS. Hybrid TMS has two part for batteries cooling, one part consists of passive cooling and the second part consists of active cooling. Usually, phase change materials are used in the passive part and in the active part, a fluid such as air or water is used. The results have shown that the increase of the cells distances in the staggered configuration from 2D to 3D between cells cannot improve cells cooling, so due to the space limitations in the car application, the compact configuration should be chosen.
