“…It aims to provide a safe, reliable and cost-efficient solution to the battery [Chatzakis et al, 2003]. The basic schematic presentation of the BMS structure is shown in Figure 1 [Chatzakis et al, 2003]. The battery voltage, current and temperature are measured and converted to the subsystems of BMS for thermal management, SOC estimation, and SOH estimation.…”

“…Although at least one fast-DC charge study has been undertaken (and shown a negative impact on cell capacity (Boesenberg et al, 2015)) and studies have been published on the design and implementation of BMS and cell equalisation methods (Stuart and Zhu, 2010;Chatzakis et al, 2003;Bowkett et al, 2013;Chol-Ho et al, 2013;Bonfiglio and Roessler, 2009), there is little information on realistic fast-DC charging of commercially available EVs. In this paper we are not looking at deterioration of battery cells through fast-DC charging (which very well may be a secondary effect), but we will concentrate on the interaction and impact of realistic fast-DC charging on BMS and battery cell balance and hence on the efficient utilisation of the given battery capacity.…”

Electric vehicle (EV) range, recharge opportunities and time to recharge are major barriers to mainstream acceptance. Fast-DC charging has the potential to overcome these barriers. This research investigates the impact of fast-DC charging on battery cell balance, charge capacity and range for an EV travelling long distances on an 'electric-highway'. Two commercially available EVs were exposed to a series of discharge and fast-DC charge cycles to measure cell balance and charge capacity. The vehicles' battery management systems (BMS) were capable of successfully balancing individual cells and hence maintaining the batteries' charge capacity. Although fast-DC charge levels and discharge safety margins significantly reduced the vehicles' charge capacity and range as stated by the manufacturer, these values remained stable for the test period. In regards to cell balance and charge capacity, our research suggests that fast-DC charging technology is a feasible option for EVs to travel large distances in a day.

“…The authors of Bhangu et al (2005) use Kalman filter (KF) to estimate a parameter of the EV battery model and distinguish state of health (SoH) of the battery. In Chatzakis et al (2003), Affanni et al (2005) and Stuart et al (2002), a series battery configuration is suggested and an electric circuit to protect the batteries from short circuit and other failure is designed.…”

In this paper a variety of battery configuration topologies for electrified vehicles are investigated with regard to reliability and expected lifetime along with the possibility of applying active fault detection to provide early warnings for the driver. Different configurations are investigated ranging from a simple single serial string of battery cells providing only the lowest level of fault tolerance, to a highly elaborate and still practically relevant triple string configuration providing fault detection and reconfiguration possibilities as well as repair. All configurations are analyzed with regard to the associated reliability profile assuming non-ageing cell failure model. A novel method for active early fault detection is presented based on encoding faults into a parametric dynamic cell model, where parameters are continuously estimated under the influence of an auxiliary test signal designed to optimize parametric sensitivity. Finally reliability profiles for all investigated configurations are compared mutually and with standard requirements on the basis of mean time to failure statistics.
