Profit analysis of electric vehicle energy storage

Is energy storage the weak point of EVs?

Abstract—With ever-increasing oil prices and concerns for the natural environment, there is a fast-growing interest in electric vehicles (EVs) and renewable energy resources (RERs), and they play an important role in a gradual transition. However, energy storage is the weak point of EVs that delays their progress.

What are the challenges of energy storage systems and EVS?

This paper presents various technologies, operations, challenges, and cost-benefit analysis of energy storage systems and EVs. The demand for the electrical energy is increasing in the modern world; however the fossil fuel-based energy systems are polluting and depleting existing the available reserves.

What is the cost-benefit method for PV charging stations?

Based on the cost-benefit method ( Han et al., 2018), used net present value (NPV) to evaluate the cost and benefit of the PV charging station with the second-use battery energy storage and concluded that using battery energy storage system in PV charging stations will bring higher annual profit margin.

What is the objective function of integrated PV and energy storage?

In this model, the objective function is to minimize energy loss. Based on the average electricity price, solar irradiance and the usage patterns of plug-in hybrid electric vehicle (PHEV), Guo et al. (2012) analyzed the energy storage configuration of charging station integrated PV and energy storage. The model aimed to minimize the cost.

What are the benefits of EVs?

EVs are propelled by electric motors and use the electrical energy stored in the batteries. EVs are required to reduce the dependence on fossil fuel and to reduce pollution as transportation accounts for one-thirdof all energy usage. By using the EVs 100%, the emission can be reduced by half.

Can time-of-use price solve the problem of EV charging load?

Due to the considerable charging power, the simultaneous charging of a large number of EV charging loads will endanger the safe operation of the power grid. Although time-of-use (TOU) price can alleviate the impact of charging load on the power grid to some extent, it cannot solve the problem fundamentally.
