One of the main concerns surrounding renewable energy is its inconsistent supply. To counter this problem, we can store energy so we can utilize it whenever we need. Vehicle to Grid (V2G) technology, by enabling bi-directional charging in electric vehicles, allows a vehicle’s battery to store energy and then release some of it back to the power system when required.
In this guide, we will discuss the following points related to bi-directional charging in electric vehicles.
- Bi-directional charging definition
- Bi-directional battery charging system and how is bi-directional charging in electric vehicles different from uni-directional charging in electric vehicles?
- Advantages and disadvantages of bi-directional charging in electric vehicles
- List of EVs that support V2G charging
Bi-directional EV Charging vs Uni-directional EV Charging
As the term ‘bi’ (Latin for ‘two’) implies, bidirectional charging is charging that goes in two directions – from the grid to the car’s battery as well as from the car’s battery to the grid. Bi-directional charging, unlike normal EV charging which uses AC power, uses an AC to DC inverter for the power conversion process.
How Bi-directional Charging Works
An EV battery uses a two-way charger to connect to the power grid which tracks the frequency of the grid to see if the supply and demand for power are in balance. When demand exceeds supply, the frequency falls, and the battery provides electricity to the grid. Conversely, the frequency rises when supply exceeds demand and the battery begins to charge in order to consume the excess load.
Advantages and Disadvantages of Bi-directional Charging
Even though we buy a car to drive around, we don’t drive it all day long. During the time it is parked, you can supply electricity to power your house for several days off a fully charged electric car battery. This can come in really handy during a power blackout.
Secondly, EV owners can earn money if their car supports bi-directional charging. In energy trading strategies, there is a concept known as arbitrage. This means that energy can be purchased from the grid at a low cost and then sold back to the grid at a higher cost.
Finally, and perhaps most importantly, the V2G concept aids in the integration of renewable energy sources. Renewable energy integration is the term used to describe the efficient storage and distribution of renewable energy with minimal environmental impact. V2G ensures the efficient use of renewable energy, thus reducing carbon footprint in cars and greenhouse gas emissions.
A major disadvantage of bi-directional charging is battery degradation. Although the processes involved in the two-way charging are performed ensuring that the vehicle has enough charging to complete its driving activities, excessive amounts and a higher rate of energy withdrawal from the battery can reduce its lifespan.
It must be noted that not all-electric cars support bi-directional charging at the moment. List of EVs known to support bi-directional charging includes Nissan Leaf, Hyundai Ioniq 5 and Volkswagen ID.4. More electric car manufacturers are planning to integrate bi-directional charging in their cars in the future.
