In this paper a Bi-directional battery is designed that parked. This batt ery charger all ows receive ener gy from the the stored energy in the batteries (V2G). From the point of intermittency (providin g both backup, storage and load-shift).
In this project we developed onboard bidirectional battery charger for Electric Vehicles (EVs) targeting Grid-to-Vehicle (G2V), Vehicle-to-Grid (V2G), and Vehicle-to-Home (V2H) technologies. During the G2V operation mode batteries are charged from the power grid with sinusoidal current and unitary power factor.
AC/DC topologies Bi-directional converters use the same power stage to transfer power in either directions in a power system. Helps reduce peak demand tariff. Reduces load transients. V2G needs “Bi-Directional” Power Flow. Ability to change direction of power transfer quickly. High efficiency >97% (End to End) at power levels up to 22KW.
Moreover, the parameters a and b are battery dependent. As inferred from Equation 9, DOD of a battery is inversely proportional to SOH of a battery. Utilisation of recycled batteries along with new batteries in a system causes SOH imbalances. For this purpose, a SOH balancing technique is proposed in for MMCs.
The standard control strategy disregards battery current faults brought on by the battery controller. The power balance equation is represented as follows: where Psc (t), and are power of SC, RES, DC grid, battery, and SC, respectively. Pss (t), and Pts (t) are steady state and transient component.
The BC can incorporate the battery and SC as HESS to alleviate the power imbalance between PV power and load demand. In addition to meeting the demands of the network operator, the proposed system also allows for the optimal functioning of a HESS integrated into a PV plant.
