At low temperatures, heating the cabin consumes a large portion of battery stored energy of an EV, which leads to a significant reduction in driving range.
It was concluded that the preheating strategy could reduce the operating cost of a plug-in hybrid electric vehicle (PHEV) by 3.40 % in 22 driving cycles in Harbin, China, which possessed good economic benefits. Geng et al. successfully synthesized the CTF/EG@PW composite through a physical blending process involving CTF, EG, and PW.
According to the discussion in Section 2, the heat generation of the battery pack and the heat transfer of HPACS are affected by the speed of the electric vehicle. Therefore, the influence of future vehicle speed on the heating process is introduced in the system model.
In order to verify the influence of the heating strategy on the battery life, the changes in the capacity and aging rate of the battery under the conditions of no heating at low temperature, heating at low temperature and no heating at room temperature are compared.
Therefore, using thermal batteries with high energy storage density to provide heat for EVs in cold environments can reduce vehicle costs, increase driving range, and prolong battery life. This is especially so for large EVs with a high heat demand such as electric buses.
According to reports, the driving range and charging and discharging performance of pure EVs such as the Nissan Leaf, Chevrolet Volt, Tesla Models, Denza, BAIC new energy EV series, and Jianghuai New energy iEV series are severely challenged by low-temperature environments.

At low temperatures, the charge/discharge capacity of lithium-ion batteries (LIB) applied in electric vehicles (EVs) will show a significant degradation. Additionally, LIB are difficult to charge, and their negative surface can easily accumulate and form lithium metal.
Lithium-ion batteries are the most commonly used battery type in commercial electric vehicles due to their high energy densities and ability to be repeatedly charged and discharged over many cycles. In order to maximize the efficiency of a li-ion battery pack, a stable temperature range between 15 °C to 35 °C must be maintained. As such, a reliable and robust …
