This paper presents the design of a power converter for electric vehicle (EV) applications energized by Li-ion battery (LiB) and supercapacitor (SC). The combination of these energy sources is a good solution for better performances of the EV. A single non-isolated bi-directional converter is proposed in order to get the lowest loss, weight and cost of total electric vehicle applications perspective. The battery voltage represents bus voltage of the power supply system connecting to the load. To control the dynamic of converter, state space averaging technique and power equation linearization are employed to get the transfer function for designing the PI controllers. In order to get the fast response of SC power energizing, the cascade controller is implemented to control current and SC voltage. MATLAB simulation is successfully verified the proposed power converter topology, configuration and controller design for EV. The result shows the capability to settling supply a significant amount of power for step load change within few milliseconds. Sudden load power demand can be drawn from SC. This can reduce the stress of battery as in case of the pure battery power supply system.

Pure electric vehicles develop rapidly all over the world. According to building the model of pure electric vehicle in the CRUISE software, first the power supply system parameters are designed and simulated, and then the power performance and feasibility of the model are verified. The design of CPS (composite power supply) which combined UC (ultra capacitor) with Li-B (lithium battery) can extend the life of the Li-B, and protect the Li-B in some way. Under the NEDC operating condition, the simulations of the SPS (single power supply) and the CPS are taken. The result shows that the variation of the Li-B SOC decrease by 8%, compared the CPS system with the SPS system, the comprehensive energy consumption economy is 6.25%.

This paper discusses the post stage power supply circuit’s structure of electronic appliances such as laptops, desktops, mobile phones and digital cameras, which are commonly used in office. The advantages and feasibilities of DC power supply’s substitution for AC are analyzed. On this basis, a DC power supply system consists of photovoltaic cells, batteries, AC/DC modules, DC/AC modules as well as DC loads is brought forward. The main power supply unit, photovoltaic cells, connects the DC bus through a DC regulator circuit. The bus voltage can be maintained stable by real-time adjustment of photovoltaic cells’ output power. The battery module connects the DC bus through a bidirectional Boost-Buck circuit. The charges and discharges of batteries can be real-time controlled according to the bus voltage level. The AC/DC module connects the DC bus as a backup, which can real-time detect the bus voltage to determine whether to start. The DC/AC module can supply power to ordinary AC loads and the DC loads are usually powered from the bus through DC/DC converters.

Electric Power Supply

In this paper, a hybrid electric power supply system for an electric vehicle (EV) is investigated. The study aims to reduce electric stress on the main energy source (fuel cell) and boost energetic performances using energy sources with high specific power (supercapacitors, batteries) for rapid traction chain solicitations such as accelerations, decelerations, and braking operations. The multisource EV power supply system contains a fuel cell stack, a lithium batteries module, and a supercapacitors (Sc) pack. In order to emulate the EV energy demand (wheels, weight, external forces, etc.), a bidirectional load based on a reversible current DC-DC converter was used. Fuel cell (Fc) stack was interfaced by an interleaved boost converter. Batteries and the Sc pack were coupled to the DC point of coupling via buck/boost converters. Paper contribution was firstly concentrated on the distribution of energy and power between onboard energy sources in consonance with their dynamic characteristics (time response). Second contribution was based on a new Sc model, which takes into consideration the temperature and the DC current ripples frequency until 1000 Hz. Energy management strategy (EMS) was evaluated by simulations and reduced scale experimental tests. The used driving cycle was the US Federal Test Procedure known as FTP-75.
