Switch charging energy storage

What are the different types of energy storage systems?

The HESS consists of two storage systems as follows: a Kinetic Energy Storage System (KESS) and a Battery Energy Storage System (BESS). Both are shown in Figure 2. The KESS is a prototype for an innovative energy storage system that uses an electric motor to store energy via the inertia of a rotating mass.

What data can be collected from a charging system?

With this setup, not only can charging-related data be collected (e.g., cell and battery voltages, current, SoC, and state of health) but also driving data (e.g., speed, acceleration, steering angle, energy consumption, and power).

Can the current state of charge be communicated between eV and charging station?

Unfortunately, the current state of charge (SoC) cannot be communicated between the EV and the charging station, as this is not supported by the low-level communication within the communication standard (IEC 61851-1 Mode 3). However, an estimated SoC is calculated by the PLC based on user input and the measured transferred energy.

Can unidirectional and bidirectional charging be integrated into a hybrid energy storage system?

In the case of bidirectional charging, EVs can even function as mobile, flexible storage systems that can be integrated into the grid. This paper introduces a novel testing environment that integrates unidirectional and bidirectional charging infrastructures into an existing hybrid energy storage system.

How to manage electrical load generated by EV charging?

Different approaches for managing the electrical load generated by EV charging can be evaluated in practice at the charging station. On the other hand, investigations related to hardware performance can be conducted, for example, the measurement of charging behavior of different vehicles.

Why are energy storage systems important?

1. Introduction Due to the high energy consumption of industrial buildings (e.g., factories, assembly plants, logistic centers) compared to the private sector (e.g., houses and apartments) and the associated high power demands and costs, energy storage systems are frequently utilized in factories and plants to optimize energy usage.
