“…The heater generates heat directly from a Litz coil by electromagnetic forces in work-pieces prepared from ferromagnetic materials, through which high-frequency AC voltage is produced. The induction heater has high-performance characteristics, and extraordinary rapid temperature increase times up to the optimal temperature [51]. The induction heater is also semi-permanent due to the lack of consumable parts [52].…”

The life and efficiency of electric vehicle batteries are susceptible to temperature. The impact of cold climate dramatically decreases battery life, while at the same time increasing internal impedance. Thus, a battery thermal management system (BTMS) is vital to heat and maintain temperature range if the electric vehicle’s batteries are operating in a cold climate. This paper presents an induction heater-based battery thermal management system that aims to ensure thermal safety and prolong the life cycle of Lithium-ion batteries (Li-Bs). This study used a standard simulation tool known as GT-Suite to simulate the behavior of the proposed BTMS. For the heat transfer, an indirect liquid heating method with variations in flow rate was considered between Lithium-ion batteries. The battery and cabin heating rate was analyzed using the induction heater powers of 2, 4, and 6 kW at ambient temperatures of −20, −10, and 0 ∘C. A water and ethylene glycol mixture with a ratio of 50:50 was considered as an operating fluid. The findings reveal that the thermal performance of the proposed system is generally increased by increasing the flow rate and affected by the induction heater capacity. It is evident that at −20 ∘C with 27 LPM and 6 kW heater capacity, the maximum heat transfer rate is 0.0661 ∘C/s, whereas the lowest is 0.0295 ∘C/s with 2 kW heater capacity. Furthermore, the proposed BTMS could be a practical approach and help to design the thermal system for electric vehicles in the future.

“…With the development of the computational electromagnetics, many numerical simulation methods have been developed and applied in the induction heating system and process [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]. Models of two dimensions and three dimensions with linear or nonlinear properties can be solved using these methods [8][9][10][11][12][13][14][15][16][17][18]. Moreover, elegant solutions have been developed to solve these models under dynamic conditions [19][20][21][22].…”

The electromagnetic field and the heat generation rate distribution in the semi-infinite body which is heated by the induction coil, are obtained by solving the Maxwell equations through the analytical method. The impacts of the air gap width, induction coil width, current density and current frequency on the heat generation rate distribution in the workpiece are studied. The results show that the heat generation rate in the workpiece is in direct proportion to the square of the eddy current density and the square of the induction coil width. The heat generation rate follows the exponential attenuation law with the increase of the air gap width. The current density has effects on both the maximum heat generation and the heat generation distribution. When the effect of the air gap is neglected, the higher the current frequency, the larger the maximum heat generation rate. However, when the effect of the air gap is considered, the maximum heat generation rate will increase with the augment of the frequency when the frequency is less than the critical frequency and decrease with the augment of the frequency when the frequency is larger than the critical frequency, which is firstly reported in the paper. Moreover, the higher the current frequency, the heavier the heat generation rate attenuation in the workpiece.
