Abstract
Battery development has evolved over time. One of the potential problems encountered is the presence of thermal runaway that occurs in the cell battery. When thermal runaway occurs, it will spread to the surrounding battery. There are various causes of thermal runaway, one of the most common is an increase in temperature that exceeds the optimal allowable limit. Additional cooling will be required in vehicles running on batteries. Battery performance needs to be maintained at a conditioned temperature- temperature settings will be useful to maintain battery pack life. The obstacle encountered in setting the battery pack temperature on electric motorcycles is the application of the swap method on the battery and the limited space for the electric motorcycle. The use of a compartment with a cooler will be a solution to keep the battery temperature at an optimal working temperature (less than 35C). The use of air conditioning in the swap-type battery compartment is able to maintain battery performance up to 12% better than without coolers.
