The Benefits of Bidirectional Charging

10 minutos

Currently on a daily basis, terms like “bidirectional charging,” “vehicle to grid (V2G)” or “vehicle to home (V2H)” are constantly being used, but do you really know what they are talking about? So let’s talk about bidirectional charging, how it works and discover some more benefits it can provide.

Just as the word bidirectional says, or in other words functioning in two directions, bidirectional EV charging is exactly that: EV charging that goes two ways. To make it clear, in a unidirectional (one-way) EV charger, electricity flows from the electric grid into the electric vehicle and with a bidirectional (two-way) EV charger, electricity can flow both ways.

This innovation can reduce the demand on the national power grid, and in return save money as you take energy that’s already been paid for back from the Electric cars. Let’s put it this way, if you’ve already paid to charge your vehicle, why not use the left-over power to run your home too? Then overnight the electric car will charge, benefiting from cheaper power rates due to lower energy demand and making this friendly to the environment. Basically the concept of this product is to enable you to use your electric car´s battery as a secondary home power source.

Benefits of bidirectional chargers

1. Financial Savings: Save Money & Make Money

In the same way that consumers of solar panels benefit, those who return energy to the grid can make the most of it saving money on off-peak energy tariffs to charge your vehicle. You can also schedule when you sell power, so you can focus on peak energy demand times and get the best price for your power.

Bidirectional charging offers you dual benefits as you can then use the power for your charging during off-peak demand for maximum cost savings. When you consider the money saved by owning an electric vehicle, thought to be between €6,000 and $10,000 over the lifetime of the vehicle, going electric is a sensible and cost-effective option.

2. Environmentally friendlier

Bidirectional charging is an excellent option to make your home even greener, if you combine it with renewable energy sources like solar panels (a great environment friendly option), with bidirectional charging you can keep your energy requirements from the grid to a minimum. Sometimes renewable energy can be unreliable due to weather conditions, using bidirectional charging could encourage the uptake of renewable energy as electric motor users can use their car batteries to store energy!

3. Better management on local power needs

The possibility of using your electric motor vehicles as a power source for your home also presents huge benefits to your neighborhood. If more EVs owners use bidirectional chargers and use at home the power they have already stored in their car, local power-surges at peak times can be avoided or better managed.

Bidirectional charger stations can potentially allow apartment residents to sell their energy back to their communal energy store, opening up the benefits to people in all types of living situations.

4. Future-proof your life

Everyday there is improvement, innovation and development on new and clean energy sources, investing now lets you be part of the current and benefit from new technology. If you are considering acquiring a new electric vehicle, keep in mind that, in a few years, bidirectional charging will be part of the new norm.
