For purpose of validating the effectiveness of the optimal charging current, the battery charging experiments with liquid cooling are carried out. As shown in Fig. 8, the battery charging experimental platform with liquid cooling is established.
In this study, considering temperature gradient effect of liquid cooling, a charging optimization strategy at a battery module level is proposed to balance the charging time and temperature difference. Genetic algorithm is utilized to determine the specific charging protocol by evaluating the fitness function.
In practical application of EVs, liquid cooling has become an efficient method to control the temperature of the battery module. However, the temperature gradient along the coolant flow direction is inevitable, which may cause uneven temperature distribution of the battery module.
A liquid cooling-based BTMS (Battery Thermal Management System) was verified to be effective in the discharging process of a lithium-ion battery module under a wide range of current rates. Panchal et al. designed a liquid cooling plate for a lithium-ion battery module during discharging at a 4C current rate.
One of the challenges for fast charging is the massive heat generated by high charging currents [ 4 ]. The appropriate operating temperature of the LIB should be within the range of 25–40 °C [ 5, 6 ]. Besides, the temperature difference in a battery module is better to be controlled within 5 °C [ 7].
To address the problem of fast charging for a lithium-ion battery module, an efficient scheduling method is required. In this study, a liquid cooling-based thermal management system equipped with mini-channels was designed for the fast-charging process of a lithium-ion battery module.
