The EV battery as a power bank

As the world continues to shift towards electric vehicles (EVs) for their environmental and economic benefits, there has been a growing interest in Vehicle-to-Grid (V2G), Vehicle-to-Load (V2L), and Vehicle-to-Home (V2H) technologies. These technologies allow for the bidirectional flow of energy between EVs and the grid or household, making it possible for EVs to not only consume electricity, but also to use their battery as a source of electricity when needed.

Let’s take a closer look at the differences between these three technologies and some examples of cars that support them:

Vehicle-to-Grid (V2G)

Vehicle-to-Grid technology allows for the flow of electricity from the EV battery back to the grid. This means that when the EV is plugged in, it can serve as a mobile battery that can send energy back to the grid during peak demand or times of power outages. This has the potential to increase the stability and reliability of the grid by providing an additional source of energy.

Example: Nissan Leaf

The Nissan Leaf was the first electric vehicle to support V2G technology. It can connect to a bi-directional charger and send power back to the grid.

Vehicle-to-Load (V2L)

Vehicle-to-Load technology allows for the use of an EV’s battery to power external devices. This means that during a power outage or in a remote location, an EV can serve as a mobile power source for tools or appliances.

Example: Mitsubishi Outlander PHEV

The Mitsubishi Outlander PHEV has a V2L system that can supply up to 1,500 watts of power to external devices through its power outlets. This makes it possible to use the car’s battery to power a camping stove, for example.

Vehicle-to-Home (V2H)

Vehicle-to-Home technology allows for the use of an EV’s battery to power a household during a power outage or times of peak demand. This means that the EV can serve as a backup power source, reducing the reliance on the grid and potentially lowering electricity bills.

Example: Toyota Prius Prime

The Toyota Prius Prime has a V2H system that allows it to power a household for up to four days during a power outage. This is made possible through a specialised power outlet that can be installed in the home.

In conclusion, V2G, V2L, and V2H technologies represent exciting new ways that EVs can interact with the grid and household. As more car manufacturers continue to develop and adopt these technologies, we can expect to see even greater benefits in terms of energy security, cost savings, and environmental impact.
