“…Meanwhile, due to the lack of prediction, the instantaneous velocity is an important reference for distributing power flow. Paper [28] develops a control policy to ensure that the supercapacitors are well charged for the possible upcoming acceleration when traveling at slow speed. Conversely, when the vehicle is running at high speed, the ultracapacitors are sufficiently discharged in preparation for a future regenerative braking event.…”

The energy storage system (ESS) is the heart of electric vehicles, which determines their efficiency, power, and driving range, etc. The emerging demand of modern electric vehicles often requires the ESS to preserve high energy density, along with the high peak power. Nowadays, batteries and supercapacitors, which could deliver high energy and power capability respectively, are commonly used as the ESS in industrial practice. A hybridization of them, the hybrid energy storage system (HESS), will potentially take their individual advantages, thus supplying a large burst of current and also storing enough energy to ensure a sufficiently long driving range. This paper reviews the state-of-the-art technology for batteries, supercapacitors, and the HESS. Various structures and topologies for the HESS are discussed, and control strategies are investigated.

“…The hybrid energy storage system included a super capacitor and a storage battery, and then was connected in parallel to the DC side of the H-bridge through DC/DC converters [4]- [6], as shown in Fig.1. The advantages of this kind of chain topology was that the scattered low voltage energy storage units were assembled into a high-power energy storage system, and the switching frequency of the power devices was increased, thus improving the quality of the current.…”

Energy storage technique is one of the most effective technique means for the regulation of wind power. Aiming at smoothing the fluctuation of wind power and maintaining bus voltage， this paper proposed a hybrid energy storage system (HESS) based on cascaded multilevel STATCOM, containing a battery and a super-capacitor. And the active and reactive power coordination control strategy was also developed. Based on these models, a simulation platform of STATCOM/HESS and wind farm was developed using PSCAD/EMTDC. Simulation results showed that the problems of wind power fluctuation and low voltage ride through (LVRT) of wind farm connected to the power grid can be well solved in the case of random wind and serious disturbance in power grid.Key word-hybrid energy storage system, cascaded multilevel STATCOM, wind power.

“…Combined use of batteries and supercapacitors has proven very beneficial in applications with large peak-to-average power ratios, such as Electric Vehicle and traction systems [1][2][3][4][5][6]. The basic idea behind such a hybrid energy storage system is to use the relatively energy dense battery as source of the bulk energy, while the power dense supercapacitors provide (or absorb) the power peaks, as schematically shown in Fig.1.…”

Abstract-A converter topology suitable for bidirectional power flow control between a supercapacitor bank and a stiff voltage source is presented. Main feature of the topology is the reduced ratings of the solid state devices used in the converter, as compared to conventional solutions. For the same capabilities in terms of energy extraction, reduction of up to 50% in the ratings of the silicon switching devices is achieved. Both simulations and experiments are performed to validate the principle.
