“…The advantages of lithium-ion batteries are high energy density, excellent performance at high temperature environment, and also it is eco-friendly. Other important features of the Li-ion batteries comprise less memory effect, high specific power, high specific energy and long battery life [15]. Due to these exceptional characteristics, lithium-ion battery is more suitable for replacing NiMH as next-generation batteries for vehicles.…”

This paper presents a flexible power control strategy of a fuel cell (FC)- battery combined hybrid power source fed DC motor drive suitable to be used in electric vehicles which can be capable of working efficiently with an straightforward control method, operating the drive precisely in FC and hybrid modes during the entire drive operation. Although Fuel Cells are very widely accepted by the electric vehicle manufacturing industries, still the power control criterion can be improved to increase overall efficiency. The most appropriate Master Slave Control technique has been implemented to control the modes based on load power requirement and transient operations. The controller with the algorithm guarantees that total load is shared exactly between the two sources all through intense load and transients conditions. Such method inevitably facilitates the fuel cell to work in normal load region throughout transient and steady state by equally sharing the load current between the master and slave converters. The efficacy of the proposed scheme is verified through simulation which is carried out using MATLAB/Simulink software. Investigational tests are carried out using LabVIEW platform with PCI 6251 DAQ I/O interfacing card for viability of the system. FC can be considered as most vital electric power and component of an electric vehicle

“…The following driving equations [15][16][17][18] are implemented to validate the master-slave control strategy in the proposed dc drive system which is suitable for electric vehicle application. As the source voltages are different, both converters are controlled at different duty cycles to maintain a common dc link voltage.…”

“…Hybrid electric bus power system structure can be divided into series hybrid electric bus (SHEB), parallel hybrid electric bus (PHEB) and parallel-series hybrid electric bus (PSHEB), according to its different decorates form [10,11]. Due to the complicated structure, PSHEB possesses the high failure rate and the increasing cost of operation and maintenance.…”

In order to obtain better economy and power performances of compressed natural gas (CNG) and electric hybrid city bus, the powertrain system is designed and studied in this paper. Based on manufacturing technology, operation cost and dynamic property, economy is regarded as the main optimization goal for CNG-electric hybrid city bus, which determines the structure of powertrain system of CNGelectric hybrid city bus. Vehicle control strategy is established by working conditions. Some key component parameters are matched and designed. Work model of motor/generator is established, and torque characteristic curve of motor/generator is obtained. Full vehicle model of CNG-electric hybrid city bus is established by ADVISOR software. Comparison with tradition natural gas city bus, the maximum gradability rises by 69.8%, the maximum gradability of 20 km/h is 25.4%, the maximum speed rises by 8.6%, and the acceleration performance of 0~50 km/h rises by 21.9%. The fuel consumption reduces by 23.3% in the BC-CTC cycle working condition, and the fuel consumption reduces by 25.1% in the ECE+EUDC cycle working condition. So, the performances of power and economy have been obviously improved, compared with traditional CNG city bus, which indicates that this method can be used to study the powertrain system of CNG-electric hybrid city bus.

“…Besides the PMS, the power transmission is another factor that impacts the vehicle performance and, also, its FC and emissions. Recently, applications of Continuously Variable Transmissions (CVTs) as a power transmission system have become common for non-hybrid and hybrid vehicles, especially for Parallel HEVs (PHEVs) [21,22]. Contrary to a series HEV, in parallel one, an Internal Combustion Engine (ICE) is mechanically connected to the wheels and, therefore, cannot operate in optimal working regions unless a CVT-type transmission is used.…”

This paper proposes a new Power Management Strategy (PMS) for parallel hybrid electric vehicles equipped with Continuously Variable Transmission (CVT). The proposed PMS is established on the basis of Electric Assist Control Strategy (EACS) and Equivalent Consumption Minimization Strategy (ECMS). This control approach is based on maintaining the battery energy within a recommended range, considering the CVT e ciency in selecting the engine operating point, and nding the best power split between the engine and electric motor at certain moments of the driving. In order to evaluate the e ectiveness of this scheme, it is compared with EACS, a modi ed version of EACS and ECMS. It is shown that, in all of the studied driving cycles, the proposed PMS is superior to the considered rival strategies in terms of fuel consumption and, also, HC and CO emissions.
