Game-Changing Innovations in Electric Vehicle Chargers

Electric vehicle charger companies are innovating at a pace that matches electric automakers.

Bidirectional charger why

 

 

Innovations in electric vehicles are widely reported, but what of the chargers and infrastructures that power this growing industry ?

One such innovation is Bidirectional Chargers. Let’s know more about it.

Bidirectional charging and vehicle-to-grid (V2G) are among the most hyped-up concepts in the electric vehicle (EV) charging industry. But what do they actually mean and what do they have to do with smart EV charging?

Innovations in electric vehicles are widely reported, but what of the chargers and infrastructures that power this growing industry?

As the name suggests, bidirectional chargers allow electricity to travel both ways. EV owners can charge their cars, but they can also send electricity the other way through vehicle-to-grid (V2G) energy transfer.

EV owners can actually get paid by the energy companies to send electricity back when demand is high.

After reading this article, you should be able to answer all these questions—and more! So let’s get down to business. 👇

Need of Bidirectional Chargers?

  • Energy demands are surging with the rise of electric vehicles. This means energy companies often give drivers better rates for charging at times when energy demands are lower — at night time, for example.

  • However, demand is only going to get higher and energy companies will actually need help from EV owners to balance the grid at the same time as incentivizing them to help out.

    That’s where the bidirectional charger comes in.

Bidirectional Charger

As the name suggests, bidirectional chargers allow electricity to travel both ways. EV owners can charge their cars, but they can also send electricity the other way through vehicle-to-grid (V2G) energy transfer.

What is bidirectional charging? And what does it have to do with V2G?

  • Bidirectional charging allows to not only charge the batteries of electric vehicles but to also take energy from car batteries and push it back to the power grid to help balance momentary spikes in electricity demand.
  • Bidirectional charging is powered by vehicle-to-grid (or V2G) technology. V2G allows to communicate with the energy system to help stabilize the power grid through demand response services.
  • Bidirectional charging and vehicle-to-grid are often used as synonyms, even though technically bidirectional charging refers to two-way charging, while V2G is the technology that allows the one-way flow of energy from the car battery back to the grid.

Bidirectional charging and smart charging

Smart EV charging, i.e. a cloud connection between an EV, a charging device, and a charging operator, is a prerequisite for bidirectional charging. Without this connection, there would be no information flowing between the power grid and the vehicle. Thus, it would be impossible to know when the power grid requires balancing.

In short, bidirectional charging can be considered a feature of smart EV charging.

The benefits of bidirectional charging

So why do we need bidirectional charging, then?

Firstly, bidirectional charging is a great way to locally manage momentary spikes in electricity consumption. Instead of having to invest a ton of money in replacing a real estate property’s electricity system to prepare for managing heavier loads, electric cars can be used as temporary energy reserves.

Secondly, the power grid and the planet both benefit from V2G, as the technology makes it possible to reserve renewable energy and pull it back into use exactly when it’s needed. Because the production of solar and wind energy is extremely unpredictable, without V2G, a lot of renewable energy would go to waste.

Thirdly, if environmental consciousness isn’t enough of a motivation for consumers, taking part in bidirectional charging is likely to become a cost-effective EV charging method. By agreeing to use their vehicles as flexible energy containment reserves, consumers will most likely be able to enjoy lower charging prices.

 

Case Study

Wallbox, has created the “first bidirectional charger for your home.” By also allowing electricity to be transferred to the home, they claim their technology will change the way we use energy — imagine a self-sufficient home where a car could be used as storage for excess solar power.

Virta, meanwhile, recently opened a public bidirectional EV charging point.
