Lithium-ion batteries (LiBs) exhibit poor performance at low temperatures, and experience enormous trouble for regular charging. Therefore, LiBs must be pre-heated at low temperatures before charging, which is essential to improve their life cycle and available capacity. Recently, pulse heating approaches have emerged due to their fast-heating speed and good

In Ref. [25], a battery-powered strategy was presented based on an external heating structure equipped with heating film (HF), which can preheat a prismatic battery pack from – 40 °C to 0 °C within 10 min. Min et al. [26] developed a charging-heating combined strategy, and they warmed up the 18,650 cell externally during charging process by controlling both the
The invention simultaneously cools the charging pile and the battery pack, reduces the cost and the system energy consumption, and improves the charging safety and the cooling effect.
Therefore, the energy required to keep the battery pack above 0 °C during the entire charging time came from the energy stored in the battery pack at the end of heating. The decrease of battery pack temperature during charging depended on the heat dissipation rate of battery pack to environment. After stopping charging, the rate of temperature
Moreover, an adaptive multi-objective optimization charging strategy for battery packs is proposed. This charging strategy can be realized without complex controller, and the existing charging pile is relatively reformed. strategy involves charging time, aging, and energy loss as optimization objectives. At the model level, the battery

Due to the high energy density and outstanding working performance, Lithium-ion (Li-ion) batteries (LIB) are widely used in most of the portable electric devices and energy-storage systems [1, 2].However, their fire safety is still a major concern due to the lower thermal stability [3].Over the last 30 years, numerous fire accidents of Li-ion batteries have been reported,
The charging pile energy storage system can be divided into four parts: the distribution network device, the charging system, the battery charging station and the real-time monitoring system .

Then the warm air could be sent to the battery pack by fans to heat the low-temperature batteries. The battery pack can be heated from −15 °C to 0 °C in 21 min. Song et al. experimentally validated the effectiveness of air heating using an external power source.
The preheating strategies need to be further explored in a battery module/pack level since cell temperature homogeneity in a pack is critical to the overall performance of the battery pack and would affect its aging processes.
The heat sheets were powered by the external power source, and their temperature could be controlled. Their experiments proved that setting the temperature of heat sheets to 50 °C is the most energy-saving heating strategy. Fig. 16. PCM-based preheating system for batteries.
Envicool was the first to launch the PACK + PCS liquid cooling unit suitable for 5MWh ESS and C&I ESS in the industry. It made its first public appearance at the exhibition. Envicool's technical experts stated that for large-capacity energy storage scenarios, we have innovatively adopted the PACK + PCS liquid cooling design.
The CHE, with its working fluid heated by hot exhaust gas, can warm up the battery pack. Later, Seo et al. systematically investigated the heat transfer characteristics of this integrated heating system by considering factors such as heat exchanger effectiveness, heat transfer rate, temperature distribution, and fluid flow characteristics.
The existing strategies are primarily grouped into external heating and internal heating. In external heating, although heat is generated outside the battery boundary, it can warm up the battery either convectively or conductively. Thus external heating strategies are characterized by the way in which the battery is directly heated.
