A Review on Battery Thermal Management for New Energy Vehicles. Lithium-ion batteries (LIBs) with relatively high energy density and power density are considered an important energy source for new energy vehicles (NEVs). However, LIBs are highly sensitive to temperature, which makes their thermal management challenging.
The charging process begins when an external power source, such as a solar panel or a power grid, supplies electricity to the battery. This electricity drives a chemical reaction within the battery, allowing it to store
Due to their great advantages including high energy density, high specific capacity, no memory effect as well as low self-discharge rate [2], LIBs are widely used in the field of portable
