Conclusions This paper presents a novel active balancing method for LiFePO 4 batteries based on chargeable and dischargeable capacity. The battery equivalent circuit model has been used to establish state space equations of batteries for the state of charge (SOC) and capacity estimation.
Battery balancing methods (BBMs) have been proposed to equalise each cell in the pack so that the capacity of each cell in the pack can be fully utilized. Currently, two common criteria used in battery balancing methods are voltage and state of charge (SOC). All the existing BBMs can be categorized into the two groups based on these two criteria.
1. Introduction In electric vehicles (EVs), a lithium iron phosphate (LiFePO 4) battery cell is one of the most widely used battery types due to its excellent characteristics such as high power density, high energy density, high reliability and long cycle life ( Mulder et al., 2013, Scrosati and Garche, 2010 ).
This paper proposes a near-field cell balancing method to be applied to batteries of higher capacity and power. This method involves a wireless power transfer to balance battery cells, which produces higher efficiency than conventional passive approaches, and faster equalization than active approaches.
Chargeable and dischargeable capacities are dynamically estimated. A robust balancing method is applied to equalise battery pack in charging and discharging processes. A balancing circuit helps get the current of each cell with one extra current sensor. The balancing method increases the discharged pack capacity in aged LiFePO 4 pack.
In the series-connected battery pack, there are cell imbalances in the pack and these imbalanced cells cannot reach the fully charged or discharged states simultaneously and the cells with the least chargeable or dischargeable capacities will limit the capacity of the battery pack ( Rahimi-Eichi et al., 2013 ).
