The basic principle is to heat electrically the storage medium parallel of charging the battery, store thermal energy efficiently and to release it at a defined temperature level during vehicle drive.
The power battery is an important component of new energy vehicles, and thermal safety is the key issue in its development. During charging and discharging, how to enhance the rapid and uniform heat dissipation of power batteries has become a hotspot.
Then, in this section, the thermal management scheme of automotive batteries will be built based on the principle of battery heat generation and combined with the working principle of new energy vehicle batteries. New energy vehicles rely on batteries as their primary power sources.
Professionals and engineers have significantly progressed in developing various thermal management techniques to optimize battery performance. Active cooling systems, including liquid cooling, air cooling, refrigeration-based cooling, thermoelectric cooling, and forced convection cooling, have been explored in previous studies.
Pesaran et al. [101, 102] recognized the need for thermal management of EV and HEV batteries in the early 2000s. Ensuring an even distribution of temperature and providing an ideal operating environment for the battery modules were both critical aspects of this process.
The findings indicated that incorporating thermoelectric cooling into battery thermal management enhances the cooling efficacy of conventional air and water cooling systems. Furthermore, the cooling power and coefficient of performance (COP) of thermoelectric coolers initially rise and subsequently decline with increasing input current.
Also, temperature uniformity is crucial for efficient and safe battery thermal management. Temperature variations can lead to performance issues, reduced lifespan, and even safety risks such as thermal runaway. Uniformity in temperatures within battery thermal management systems is crucial for several reasons: 1.

Battery storage can help with frequency stability and control for short-term needs, and they can help with energy management or reserves for long-term needs. Storage can be employed in addition to primary generation since it allows for the production of energy during off-peak hours, which can then be stored as reserve power.

Here are two of the most common EV cooling methods:1. Air cooling: This method employs air to cool the battery. When air runs over the surface of a battery pack it carries away the heat emitted by it.
Proper cooling technology can reduce the negative influence of temperature on battery pack, effectively improve power battery efficiency, improve the safety in use, reduce the aging rate, and extend its service life.
Immersed liquid-cooled battery system that provides higher cooling efficiency and simplifies battery manufacturing compared to conventional liquid cooling methods. The system involves enclosing multiple battery cells in a sealed box and immersing them directly in a cooling medium.
The system involves submerging the batteries in a non-conductive liquid, circulating the liquid to extract heat, and using an external heat exchanger to further dissipate it. This provides a closed loop immersion cooling system for the batteries. The liquid submergence and circulation prevents direct air cooling that can be less effective.
The current review summarizes recent research works over the span of 2018–2023 on advanced cooling strategies for battery thermal management systems in EVs. Research studies on air cooling and indirect liquid cooling, used as conventional techniques for battery thermal management, are briefly elaborated.
Effective battery cooling measures are employed to efficiently dissipate excess heat, thereby safeguarding both the charging rate and the battery from potential overheating issues. Furthermore, EV batteries may require heating mechanisms, primarily when exposed to extremely low temperatures or to enhance performance capabilities.
Four cooling methodologies were compared experimentally in, those methods are as follows: using natural convection, immersing the battery cell/pack in stationary dielectric fluid with/without tab cooling, and immersing the battery cell/pack in flowing dielectric fluid with tab cooling using water/glycol as a cooling medium.
