Electric vehicle charging station battery storage systems
Growing number of electric vehicles on the road demands an intelligent EV charging infrastructure.One of the notable changes to infrastructure we are seeing is the combination of EV charging equipment with battery storage system.
Energy storage solution enabling EV charging operators to build faster , reliable,future proof EV charging networks.
The capture and storage of energy for later use is of growing importance in today’s world.
The six main energy storage technologies are thermal storage, compressed air energy storage, hydrogen, pumped hydroelectric storage, flywheels and batteries. Amongst these techniques, the battery storage system is a convenient and reliable option for EV charging.
What is a battery storage system ?
We use fluids like petrol or gases to store energy and reuse it when needed ,the same principle, we can store electric energy in batteries
A Battery Storage System is a technology developed for storing electric charge through the use of specially developed batteries, such as used lithium-ion electric batteries.
two ways that the batteries from an electric car can be used in energy storage. First is a vehicle-to-grid (V2G) system, where electric vehicles can be used as energy storage batteries, saving up energy to send back into the grid at peak times. Second is lithium-ion batteries.They can be reused as stationary energy storage batteries.
How does V2G WORK ?
With vehicle-to-grid, an electric vehicle user can therefore decide to store electricity when rates are the lowest, then use it when the price goes up.In simple words charging becomes bidirectional process.The network no longer simply supplies the vehicle’s battery with electricity, it also considers this battery as a power source to be used to meet various energy consumption needs.
Advantages of V2G
Let's take an example: When you are returning home after office hours ,you can use the energy stored in his electric car’s battery to power his household appliances.You can recharge the battery in the night when the electricity supplier offers the cheapest rates.
vehicle-to-grid is also a key component in the creation of an intelligent distribution network, known as a smart grid, in which energy flows are constantly being optimized.
V2G also gives flexibility to optimize renewable energy sources.a battery can be charged during the hours that energy is being produced by renewable sources, and then that electricity can be used when solar or wind power is unavailable
Reasons that make Battery storage system interesting
Carbon footprint-Installing solar batteries allows you to reduce your home’s carbon footprint and move closer to self-sufficiency. Solar energy systems create much less pollution than traditional fossil fuels, and by using battery storage systems, you can ensure any energy produced does not go to waste.
Extending the life of lithium-ion electric vehicle batteries makes them more economical and lessens their carbon footprint.
Reduce demand charges- Battery storage systems can help to reduce demand charges by storing electricity during low demand and then releasing it when EV charging stations are in use.This can reduce overall cost of charging EVs.
Improved reliability- Battery storage system can provide power backup to charging stations during power outages or other disruptions ensuring that EVs can be charged even when grid is unavailable.
Increase renewable energy use -Using renewable energy sources to power EV charging stations makes it possible to reduce greenhouse gas emissions and improve overall sustainability of the transportation sector.
Improved efficiency -Battery storage system improves efficiency of EV charging stations by reducing the amount of electricity loss during transmission thus optimizing the charging process.
Convenience -Locations where access to electric grid is limited battery storage system provide reliable and on demand charging.This can help to improve overall convenience of users ,they can charge their EV anywhere.
