“…When charging battery, the power is doomed through DC/DC, whose average efficiency is 97% [11], so the battery efficiency is 94.6% eventually. Take the efficiency of battery and SC into Equation (4), and calculate the values of the left and right sides in Equation (4) varying by the output power of engine.…”

Abstract. A hybrid energy storage system (HESS) composed of a battery and super-capacitor (SC) can make full use of advantages in energy and power density, which can further improve the performance of hybrid electric vehicles (HEV). Most studies have been limited to configuration and control to reduce the burden and prolong the life cycle of the battery, seldom focusing on the redesign of energy management strategies (EMS) for HEVs when passing from battery-only energy storage to HESS. In this paper, the equivalent fuel consumption during parallel-charging of a semi-active HESS in a series-parallel HEV under rule-based EMS was deduced, and a fuzzy-logic based (FLB) CS for the HESS was established using the state of energy (SOE) of the battery and SC as inputs. This allows the requirement of energy balance for HESS to be clearly expressed. Furthermore, the regulated EMS for HEV, which could dynamically manage the high efficiency of the engine and maintain the real-time charging/discharging capability of HESS, was proposed and verified under hardware in a loop test (HIL). Quantitative comparison of results between HESS and battery-only indicated that velocity-based SC'SOE-adjustable EMS presented in this paper could make better use of SC in filtering than SOE-constant EMS, and improve the fuel economy of HEVs from 22.76 l/100 km (battery-only) to 21.18 l/100 km. In order to emphasize the advantages of management, the electric energy usage/loss and efficiency under city driving-cycle were also presented.

“…For the current state-of-the-art works on the subject, the reader is referred to papers such as [10][11][12][13][14][15]. Romaus et al [10] addressed the problem of controlling the power flows of a hybrid energy storage system combining batteries and double layer capacitors, and proposed the use of self-optimization methods that can consider various operating conditions and take into account several partly conflicting objective functions.…”

“…The results of [13] showed the potential improvement in battery lifetime of HPSS in a wind power system without applying any optimization methods. Blanes et al [14] considered the implementation of a hybrid energy storage system using ultracapacitor, and investigated a simple FPGA control method with a bidirectional buck-boost converter for an electrical vehicle HPSS system. In the method in [14], the battery supplies the low frequency part and the supercapacitor supplies the high-frequency part of the motor current, which reduces the battery stress and softens the battery peak current.…”

Abstract:Recently, the optimization of power flows in portable hybrid power-supply systems (HPSSs) has become an important issue with the advent of a variety of mobile systems and hybrid energy technologies. In this paper, a control strategy is considered for dynamically managing power flows in portable HPSSs employing batteries and supercapacitors. Our dynamic power management strategy utilizes the concept of approximate dynamic programming (ADP). ADP methods are important tools in the fields of stochastic control and machine learning, and the utilization of these tools for practical engineering problems is now an active and promising research field. We propose an ADP-based procedure based on optimization under constraints including the iterated Bellman inequalities, which can be solved by convex optimization carried out offline, to find the optimal power management rules for portable HPSSs. The effectiveness of the proposed procedure is tested through dynamic simulations for smartphone workload scenarios, and simulation results show that the proposed strategy can successfully cope with uncertain workload demands.
