Preheating batteries in electric vehicles under cold weather conditions is one of the key measures to improve the performance and lifetime of lithium-ion batteries. In general, preheating can be divided into external heating and internal heating, depending on the location of the heat source.
In addition, the serial ventilation blast volumes had an impact on preheating performance . A greater serial flow rate of the battery pack can lead to a longer the preheating time but a smaller temperature difference. However, there is no study on the effect of air preheating on the lifetime of batteries.
The features and the performance of each preheating method are reviewed. The imposing challenges and gaps between research and application are identified. Preheating batteries in electric vehicles under cold weather conditions is one of the key measures to improve the performance and lifetime of lithium-ion batteries.
To conduct the heat efficiently, the heat spreaders may be placed between batteries to enhance the heat transfer from the module to the cold plates. Because of the flat shape, the cold plates are widely used in battery module, consisting of prismatic cells instead of cylindrical cells.
However, the uneven distribution of temperature inside the battery can lead to degradation of electrode materials, thereby reducing the battery's lifetime . The methods identified from the literature are summarized in Table 1. Air preheating has been chosen as the baseline because it is the most commonly used and mature.
“ (The rocks) in the box right now are about 1,600 degrees Celsius,” Andrew Ponec said, standing next to a thermal battery the size of a small building. That is nearly 3,000 degrees Fahrenheit, “Hotter than the melting point of steel,” he explained.
Batteries generate a lot of heat during operation and their temperature must be brought down within operating ranges. At high temperatures (between 158°F and 212°F, or 70°C and 100°C), thermal runaways can occur, causing a chain reaction that destroys the battery pack. During fast charges, batteries must be cooled down.

Since the temperature involved in storing energy in an energy-dense non-phase change energy storage medium (for example, ceramic) is very high, the difference between the temperature of the energy storage material and the surroundings is also very high when the battery is charged. This means that the rate at which energy is lost to the surroundings (unwanted discharge of …
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.
