View moreFirstly, a topology structure for a low-temperature charging preheating system with an integrated dissipative balancing system was designed, which uses heating plates as both preheating elements and balancing resistors. This structure can enhance the balancing capability and achieve both preheating and balancing functions for the battery pack.
Battery pack low-temperature charging preheating strategy The required charging time of the battery pack depends on its state of charge before charging, the ambient temperature during charging, and the insulation effect of the battery pack.
The strategy proposed in this paper optimizes the functionality of common chargers, enabling simultaneous charging and rapid, safe, low-temperature heating of a battery without the need for external heating elements or additional AC excitation equipment.
Many researchers have studied the low-temperature preheating technology of battery packs to improve the performance of power battery packs under low-temperature conditions. At present, the low-temperature preheating technology for batteries is mainly divided into internal heating technology and external heating technology [ 13 ].
Pumped thermal energy storage (PTES) is a technology for intermediate storage of electrical energy in the form of thermal energy. In this work, PTES systems based on a transcritical CO 2 charging process are investigated. A two-zone water storage tank with a storage temperature of 115°C is used as thermal energy storage.
Thermal energy storage (TES) systems can help store energy on the timescales of these fluctuations. TES units are integrated into pumped thermal energy storage (PTES) systems, which operate through three subprocesses: charging, storage and discharging.
