“…Battery management systems were not used because of their high cost and complexity. To improve the performance of every battery system, Li-ion, NiCd and NiMH-based batteries were oversized and tested preliminary using ASK 2.5.10.8 multichannel chemical power sources analyser made by Yarostanmash LLC [7]. Three charge-discharge cycles with the 0.1C current were taken for each battery to estimate the energy capacity and the equivalent series resistance (ESR) for each unit during the third cycle.…”

Abstract. Diesel or gasoline engine cold cranking is a serious problem for different vehicle operation in northern countries. The engine starting torque is usually provided by an on-board electrochemical battery represented by a lead-acid unit. Modern energy storage devices, such as supercapacitors (SCs), lithium-ion, nickel-cadmium (NiCd) and nickel-metal hydride (NiMH) batteries react differently on low temperatures. Moreover, capacity losses also occur. Considering wide applications of such storage devices in electrical vehicles, their behaviour at low temperatures is of interest. Physical simulation of storage battery cold cranking was carried out using a climate chamber. Lithium-ion, NiCd, NiMH and lead-acid batteries were tested individually and paired with a SC unit to generate a power impulse for engine cranking. A number of experiments (up to five) for each type of storage devices were taken. The best performance results both for direct and hybrid cranking simulation were showed by LiFePO4-based and Ni-Cd batteries. The SC module itself showed the best performance, but its specific energy capacity cost is too high to have a large battery system based on SCs only. In this case a combined storage could give enough power to fulfill cranking demands.

“…Much better performances can be achieved by semi-active and active HESS configurations, which exploit one or more DC/DC converters for decoupling BP and UM [36][37][38][39][40][41][42][43]. Particularly, Figure 4 shows an active parallel configuration, in which BP and UM are parallel-connected to the DC-link both through DC/DC converters.…”

This chapter addresses potentialities and advantages of a highly integrated hybrid energy storage system (HESS) for electric propulsion and smart grids. This configuration consists of a highly integrated battery-ultracapacitor system (HIBUC) and aims to benefit from the advantages of both passive and active HESS configurations. Particularly, the integration of the ultracapacitor module (UM) within the DC-link of the DC/AC multilevel converter enables the decoupling between DC-link voltage and energy content without the need for any additional DC/DC converter. As a result, HIBUC benefits from simplicity and energy flow management capabilities very similar to those achieved by passive and active HESS configurations, respectively. This is highlighted properly by a theoretical analysis, which also accounts for a comparison between HIBUC and both passive and active HESS configurations. Some HIBUC application examples are also reported, which highlight the flexibility and potentialities of HIBUC for both electric propulsion systems and smart grids.

“…Most of the energy demand can be satisfied by the SC individually. For the rest, the battery can provides the auxiliary energy for adjusting the SC voltage so that the SC voltage can be controlled in the range between the upper and lower boundary [13,18], as shown in Figure 17a.…”

Both the battery/supercapacitor (SC) and SC/battery are two common semi-active configurations of hybrid energy storage systems (HESSs) in hybrid electric vehicles, which can take advantage of the battery's and supercapacitor's respective characteristics, including the energy ability, power ability and the long lifetime. To explore in depth the characteristics and applicability of the two kinds of HESS, an analysis and comparison study is proposed in this paper. Based on the data collected from public transit hybrid electric bus (PTHEB) with battery-only on-board energy storage, the range and distribution probability of electric power/energy demand is comprehensively statistically analyzed with the decomposing and normalizing methods. Accordingly, the performance of each topology under different parameter matching conditions but same mass, volume and cost values with battery-only energy storage, are presented and compared quantitatively. The results show that both HESS configurations can meet the electric power demand of the hybrid electric vehicle (HEV) through reasonable design. In particular, the SC/battery can make better use of the SC features resulting in high efficiency and long life cycles compared with the battery/SC. Equally, it proves that the SC/battery topology is a better choice for the HEV. Finally, an experimental validation of a real HEV is carried out, which indicated that a 7% fuel economy improvement can be achieved by a SC/battery system compared with battery-only topology.
