Extended range energy storage

What is the energy management strategy for extended range electric vehicles?

An energy management strategy for extended range electric vehicles is proposed. A joint simulation model is built in Cruise and Simulink. Multi-island genetic algorithm is adopted to optimize variables globally. Fuel economy of extended range electric vehicles is investigated.

What is extended range electric vehicle (EREV)?

As one type of new energy vehicle (NEV), extended range electric vehicle (EREV) demonstrates outstanding performance in terms of driving range and energy saving and emission reduction, and has become one of the top priorities of auto manufacturers for future research.

What is solar energy storage extended range (SES-ER)?

Solar Energy Storage Extended Range (SES-ER) Solar photovoltaic cells (PVCs) generate electricity by absorbing sunlight and converting it to electric current. Vehicle companies favor solar energy storage (SES) systems for their cleanliness, safety, and economic performance.

Are extended range electric vehicles a good solution?

Extended range electric vehicles (EREVs) are an effective solution to solve the lack of driving range of pure electric vehicles. Reducing the fuel consumption of EREVs and prolonging the service lifetime of battery play a positive role in solving environmental pollution and energy crisis.

What is the difference between Erev and range extender?

EREV works in electric vehicle (EV) mode while electric energy of battery is sufficient, the range extender generates energy only when electric energy of battery is insufficient. Commonly used range extenders include internal combustion engine (ICE)-generator set, fuel cell (FC), battery and so on.

What is the energy storage system of Erev?

The energy storage system of EREV is mainly composed of two parts: HESS and APU. The APU is connected to the power bus and can work with the HESS. According to the driver's instructions, the required power is shared by the APU and the HESS. Table 1 lists the key parameters of target vehicle.
