The widespread adoption of battery energy storage systems (BESS) has been hindered by the uncertainty of their financial value. In past research, this value has been estimated by optimizing the system’s actions over the course of the battery’s lifetime. However, these estimates did not consider the fact that battery actions decrease the lifetime itself. This paper uses realistic battery cycle d...

background: the interaction between serum neuron-specific enolase (nse), biogenic amino-acids and neurobehavioral function with blood lead levels in workers exposed to lead form lead-acid battery manufacturing process was not studied. objective: to evaluate serum nse and biogenic amino-acids (dopamine and serotonin) levels, and neurobehavioral performance among workers exposed to lead from lead...

In order to improve battery technology understanding the capacity fading method in batteries is very important. Battery models can be used to predict their behavior under various operating conditions. Here we proposed a simple dynamic model of lithium-ion battery with MATLAB/Simulink to observe the output characteristics of this energy storage device. Dynamic simulations are carried out, includ...

A scroll expander exhaust recovery system with the battery is proposed to improve exhaust recovery efficiency. Based on the exhaust flow, storage pressure and the battery current, expander supply pressure was optimized with the loss model based on the expansion and generator loss. And then the supply pressure controller was designed to track the optimized supply pressure reference using the inp...

The charging infrastructure plays a key role in the healthy and rapid development of the electric vehicle industry. This paper presents an energy management and control system of an electric vehicle charging station. The charging station (CS) is integrated to a grid-connected hybrid power system having a wind turbine maximum power point tracking (MPPT) controlled subsystem, photovoltaic (PV) MP...

This paper proposes three near optimal (to a desired degree) deterministic charge and discharge policies for the maximization of profit in a grid-connected storage system. The changing price of electricity is assumed to be known in advance. Three near-optimal algorithms are developed for the following three versions of this optimization problem: 1) The system has supercapacitor type storage, co...

We present a theoretical framework to calculate how storage affects the energy return on energy investment (EROI) ratios of wind and solar resources. Our methods identify conditions under which it is more energetically favorable to store energy than it is to simply curtail electricity production. Electrochemically based storage technologies result in much smaller EROI ratios than large-scale ge...

Electric Vehicles (EVs) require energy storage system that can address its fast changing load requirements such as sudden acceleration or quick regenerative braking by being able to supply or absorb high power as demanded. Lead Acid Batteries, commonly used in cheaper EVs (like electric tempo in Nepal), can properly supply these variable loads and get recharged but this mode of operation drasti...
