With the number of electric vehicles on the road increasing, the demand for electricity to charge them would spike exponentially too. While electric mobility is largely centered around cities, there arises a problem at certain periods of the day when industrial and residential electricity demand is the highest. Charging electric vehicles at these times would overwhelm the grid. But, if electric vehicles could supply the energy to the grids at these times, while being charged at low demand times, there will be a safe power transmission throughout the day. Many OEMs and charging service providers are trying to enable this scenario by developing a V2X charging technology to power the grid and buildings from the vehicles.
Nissan – Using fleet vehicles for grid balancing
- In collaboration with TenneT and The Mobility House, Nissan is using its LEAF models used in fleets to stabilize German power grids during periods of peak demand.
Panasonic, a diversified technology company, launched urban microgrids, hybrid Energy Storage Systems (ESS) with end to end solutions for Indian market. The integrated solar power microgrids feature efficient, reliable and intelligent power storage solutions to power up urban residential and commercial areas.
- The solution allows grid interaction, remote monitoring and data analytics that helps in optimizing the energy usage. Microgrids would enable uninterrupted power supply and enhance operational flexibility for distribution utilities, which are facing challenges in coping up with the increasing demand and network stress, poor power quality and losses, etc.
Nuvve corporation’s vehicle-to-grid (v2g) platform enables a new phase of project providing grid services in Japan in a project led by Toyota Tsusho corporation.
- The demonstration will survey how excellent the ability of the V2G system to balance demand and supply of electricity is, and what impacts V2G has on the power grid. In addition to ordinal usage of EVs/PHVs such as by transportation, the group seeks to produce new values of EVs/PHVs by providing V2G services even when EVs/PHVs are parked.
Audi worked with German IT service provider GISA and other software and hardware partners to simulate an overload scenario on a local power grid – based around multiple electric vehicles charging at the same time and with high power on a street supplied by a local network transformer.
- The small-scale test highlighted how intelligent and grid-optimised charging, through the intelligent management of charging procedures, can prevent grid overload.
- Specifically, utilising a device known as a smart meter gateway which provides targeted communication between the charging electric car and the grid operator, charging can be scheduled to take place during periods of lesser grid demand.
- This technology allows EV charging to be controlled to reduce stress on the grid, and can control charging capacity, charging time, and charging duration.
