Integrating large-scale renewable energy sources and electric vehicles into the power grid, Smart Charging and Vehicle-to-Grid of the electric vehicles play an important role for supply and demand matching in the power grid. The integrated control schemes considering the vehicle user's convenience, battery condition during the idle time, and grid-friendly contribution, have been designed. It is also important to implement the control schemes into the commercial electric vehicle and its supply equipment. This paper describes a laboratory test system of Smart Grid and E-Mobility consisted by an electric vehicle battery test bed, a bi-directional controllable charger, an interface controller with flexibility in communication and control, and a real-time digital simulator. Communication and control functions of each component are confirmed through fundamental experiments, and the load frequency control schemes are implemented to the system.

Controller area network (CAN) is one of the popular networks with the international standard,and adopted mostly on the vehicle.SAE J1939 is designed to allow electronic devices from different vendors to communicate with each other through a standard architecture.CAN communication length have some relationship with CAN bus rate,which may influence the rate choice and network topology.We design a CAN network with distributed control systems for a pure electric vehicle.The identification bit implementation of data for vehicle controllers is present in accordance with J1939 protocol.The vehicle network topology is considered based on controlling functions and CAN bus harness arrangement.The communication process for them is given based on CANoe platform and finally tested in real electric vehicle environment.

The parameters matching of the hybrid powertrain system of the hybrid electric vehicle has a directly impact on the performance of the vehicle dynamic and the fuel economy.The preliminary match of the powertrain system base on analysis of Driving Cycle is done,then the software of AVL-Cruise and Matlab are integrated with Isight to optimize parameters of match,by using the Multi-Island GA and NLPQL to establish the combinatorial optimization algorithm.The results show that the fuel economy have been improved by 10.92％ without sacrificing the dynamic performance and under the premise of ensuring the limits of the state of charge of battery.

Oshkosh Corporation (OSK) is taking an aggressive approach to implementing advanced technologies, including hybrid electric vehicle (HEV) technology, throughout their commercial and military product lines. These technologies have important implications for OSK's commercial and military customers, including fleet fuel efficiency, quiet operational modes, additional on-board electric capabilities, and lower thermal signature operation. However, technical challenges exist with selecting the optimal HEV components and design to work within the performance and packaging constraints of specific vehicle applications. OSK desires to use unique expertise developed at the Department of Energy's (DOE) National Renewable Energy Laboratory (NREL), including HEV modeling and simulation. These tools will be used to overcome technical hurdles to implementing advanced heavy vehicle technology that meet performance requirements while improving fuel efficiency.

This paper proposes a charging algorithm which is based on the Estimation of Distribution Algorithm (EDA) for Plug in Hybrid Electric Vehicle (PHEV).The proposed algorithm shifts the peak of power supply,satisfies the requested State of Charge (SoC [％]),and minimizes the charging cost.The proposed algorithm uses flexible weight for charging and upper charging limit to each PHEV to minimize the charge amount in peak time.The simulation result shows that the proposed algorithm shifts the peak of power supply in commute time zones,satisfies SoC of 93％ PHEVs,and reduces charging cost by 31％ compared with conventional EDA algorithm.

This paper proposes a wheel slip control strategy for 4WD Electrical Vehicle with In-wheel Motors.In the first part of this paper,a brief introduction of sliding mode control for acceleration slip regulation is given.Consider that its control effect varies with road conditions,another algorithm which can automatically adapt to different roads is designed.This method takes advantage of the peculiarity of the longitudinal static tire force curve and regulates wheel slip ratio to the detected optimal value,aiming to maximize the traction force while preserving sufficient lateral tire force.Simulation results show that the slip rate can be regulated to a value around the optimal slip ratio,and the driving torque is very close to the maximum transmissible torque.The control strategy achieves stronger stability,shorter driving distance and hence better control performance.
