1. Introduction
With the rapid progress in lithium ion battery chemistry, large scale electric energy storage becomes possible nowadays. Large battery packs such as battery energy storage stations or electric vehicles (EVs) consist numerous battery cells [1,2]. However, cells always have inevitable variations which may come from manufacturing process or the operation environment [2–5]. A battery management system (BMS) is therefore required to manage and monitor all cells as well as the overall states of the battery pack. A fully functional BMS should fulfil the following requirements: (1) Sensing and monitoring: all kinds of BMSs at least monitor the total current, the total voltage, voltages and temperatures of individual cells, as well as temperatures of the specified nodes in air [6]; (2) Power management: good power management will not only improve the life of battery packs or reducing the charging cost [7,8] but also precisely detect battery cell parameters by speci- fic methods [9,10]; (3) State estimation: state of charge (SOC), state of health (SOH) and state of function (SOF) are calculated and are extensively investigated in literature [6,11,12]; (4) Thermal management: good thermal management guarantees preference temperature to make battery packs work well and temperature uniformity between cells is a more critical issue for better thermal management [13]; (5) Communication: as the modular topology is commonly applied in the BMSs, CAN (Controller area network) bus, the most typical communication link in the automotive environments, is commonly used in BMSs [14]. Daisy chained network is also a current focus in engineering for the BMS network. The future networks could be Flexray [15], and wireless commutation also draws much attention; (6) Cell balancing: BMS needs to equalize the cells in order to maximize the battery’s capacity and life [16,17]; (7) Fault detection: battery system faults can be generally categorized into two types: system related faults and battery related faults which are intensively studied [18,19].
