“…Literature six puts forward a kind of pulse frequency current control technique. When the state of charge(SOC) raises from 20% to 80%, it takes approximately 16 minutes, and the temperature rise is less than 4℃ [6]. As shown in fig.5, compared with constant voltage mode, pulse frequency charge is much quicker and the charging time could be less than 20 minutes.…”

Copying with the increasingly severe energy crisis and air pollution, new energy vehicles will be an inexorable trend in the near future. The E-Cell electric engineering vehicles will replace conventional oil-fired ones gradually. This paper analyses the current situation and tendency of EVs in brief, explains the function of E-Cell electric engineering vehicles and its roles in maintaining grid stability, peak load shifting and 24-hour emergency rescue service for EVs. Concerning technical application, this paper primarily designs vehicle intelligent terminal systems, Battery Management System(BMS), cable charging, wireless charging and self-charging systems. Finally, this paper designs the billing modes of charging process, and accounts for billing process of vehicle intelligent terminal systems by flow chart to ensure the accuracy during charging process.

“…4: charging mode, discharging mode, and idle mode. Charging mode will operate Q 1 converter for desired current and voltage command from an EV via CAN bus and CHAdeMO protocol; whereas, the discharging mode will operate Q 2 converter and turning on an IGBT for releasing energy back to the grid for performing pulse charging technique as reported in [9]. The idle mode will operate during resting time if the temperature of the battery is increasing over than threshold value which is 5 o C for Nissan LEAF case.…”

An electric vehicle (EV) quick charger based onCHAdeMO standard with grid-support function is proposed in this paper. The current source modular converter configuration is used to perform the charging pulses with both positive and negative pulse to achieve required time for an EV which is less than 30 minutes. The use of current source converter can offer the inherit fault tolerance capability and bidirectional power flow. CHAdeMO protocol is modified for grid-support function. The 50 kW prototype is developed to validate the proposed notion. The simulation and experimental results illustrate that the proposed pulse frequency charging technique requires about 16 minutes to fully charge of the battery from 20% of SOC to 80% of SOC. The results suggest that the proposed technique can be applied for an electric vehicle quick charger station.

“…The result of this study is a higher degradation of the electrodes in the case of the PC protocol. However, by adapting the pulse frequency, it has been demonstrated the effectiveness of this protocol in comparison with the CCCV method in terms of charging time and battery lifetime [5,6,7,8]. It can be also observed that by modifying the relaxation time and current amplitude during the charging stage, it is possible to minimize the concentration polarization and optimize the charging process [6,9].…”
