1. Introduction With increasing global environmental awareness, the demand for battery systems designed for electric and hybrid vehicles is growing rapidly in recent years. Due to their long cycle life, low self-discharge rate, high energy and power density [1], Lithium-Ion (Li-Ion) batteries have emerged as the favored energy storage
In addition, since the shunt resistor is directly connected in series with the circuit, energy in the energy storage device will be consumed, which reduces the efficiency of the system [31, 32]. In addition, shunt resistance is also affected by ambient temperature, which limits its application.
