“…Normal driving, fuel cell as the energy source of the motor, and give the super capacitor charging, super capacitor terminal voltage is low, if the super capacitor side and the side of the DC bus voltage potential difference is large, easily result in excessive charging current, damaged super capacitor, so normal driving mode, super capacitor charging requirements are: to ensure a stable DC voltage side voltage, the super capacitor terminal voltage is close to the rated voltage, constant voltage charging method can be used [14].…”

A new 16-phase interleaved bidirectional dc/dc converter is developed featuring smaller input/output filters, faster dynamic response and lower device stress than conventional designs, for hybrid vehicle applications. The converter is connected between the ultracapacitor (UC) pack and the battery pack in a multisource energy storage system of a hybrid vehicle. Typically, multiphase interleaved converters require a current control loop in each phase to avoid imbalanced current between phases. This increases system cost and control complexity. In this paper, in order to minimize imbalance currents and remove the current control loop in each phase, the converter is designed to operate in discontinuous conduction mode (DCM). The high current ripple associated with DCM operation is then alleviated by interleaving. The design, construction, and testing of an experimental hardware prototype is presented, with the test results included. Finally, a novel soft switch topology for DCM operation is proposed for future research, to achieve zero-voltage switching (ZVS), or zero-current switching (ZCS) in all transitions.Index Terms-Battery, discontinuous conduction mode, energy storage system, multiphase interleaved dc-dc converter, PHEV hybrid electric vehicle, soft switching, ultracapacitor.

“…Nowadays, a lot of equalization structures and balancing strategies have been proposed [4]- [18], and summarized in [2], [15]. In considerations of energy consumption and transformation, they can be divided into dissipative balancing method [4]- [5] or non-dissipative balancing method [6]- [18].…”

“…However, relatively complex circuits limit the deployment for rapidity, stability or efficiency. To solve the deficiency, utilization of a high-performance control strategy [12]- [15] is essential. Fuzzy control [11] is beneficial to reduce balancing time, while PI control [12] is an effective method to improve balancing accuracy.…”

Li-ion battery is becoming the optimal choice for EV's power supply. In order to keep the Li-ion battery away from charging damage and prolong the battery's life, we present and evaluate here a special control strategy based on dynamic balanced point along with a non-dissipative equalizer. The main focus of the proposed control strategy is to insure that individual cell of a battery pack will be rapidly, efficiently and simultaneously balanced by adjusting equalizing current dynamically. In this paper, a model of four series connected Li-ion batteries pack has been established to evaluate proposed control strategy. The superior performance is shown by the simulation.
