The operating temperature range of an electric vehicle lithium-ion battery ranges from 15°C to 35°C and this is being achieved by a battery thermal management system (BTMS). Owing to the efficiency of these systems, a considerable amount of work has been performed beforehand.
A forced-convection battery cooling technique is investigated for a square-shaped and a rectangular-shaped battery pack consisting of 16 cylindrical LIB cells and concluded that the heat dissipation of the battery pack depends on its shape along with the different parameters.
With the increase in the usage of batteries, efficient energy storage, and retrieval in the batteries has come to the foreground. Further, along with a few other parameters, the operating temperature of the battery of an electric vehicle plays a vital role in its performance.
Electrochemical operation and joule heating due to the passage of electrons within a battery cell are the two main sources of heat creation in a battery cell. The temperature range of 25–40 °C is excellent for Li-ion batteries, whereas temperatures beyond 50 °C are hazardous to the batteries’ lifespan.
Also, the internal heat generation limits the performance of the lithium-ion batteries. The operating temperature range of an electric vehicle lithium-ion battery ranges from 15°C to 35°C and this is being achieved by a battery thermal management system (BTMS).
Kim et al. (2014b) simulated the consequences of temperature variation and thermal runaway on the simple operation of a battery cell. These simulations assisted in the improvement of temperature regulation techniques and can be used in the design of BTMS; with improved battery performance by up to 58.4%.
