Economic Sustainability of Thermal Waste Management in Electric Vehicle Batteries

Abstract

The performance and life of a li-ion battery is affected by the working temperature of the battery, the heat generated when the battery is operating can cause problems with the battery, such as reducing its life and in the worst case an explosion will occur. This study aims to determine the economic feasibility of applying heat pipes to the disposal of thermal waste batteries for electric vehicles). Economic analysis is studied in terms of optimizing battery costs with a heat pipe cooling system against batteries without a cooling system. The process of calculating the economic value carried out includes calculating the BCR (Benefit Cost Ratio) value and NPV (Net Present Value) value. The BCR value obtained shows the number 1.28. The NPV value shows a figure of IDR 2,050,740 which exceeds the number 0. The use of heat pipes can be an alternative for managing battery thermal waste. The BCR value minimizes the level of risk from investing in a project or unit. The NPV value also shows that the project can be accepted economically and the next process can be carried out.
