Bidirectional inverter AC charging

What are AC & DC bidirectional Chargers?

AC and DC bidirectional chargers ensure transforming power back from car-friendly electricity (DC) back to normal home electricity (AC). This way, you can take the energy stored in the car's battery and use it to power your house or give some back to the grid.

How does a bidirectional charger work?

Bidirectional chargers convert AC (alternating current) from the grid into the high-voltage DC (direct current) needed to charge an EV. When discharging, they reverse the process, sending energy back as usable AC power - similar to how batteries like the Tesla Powerwall work. ▶️ MORE: Watt is Bidirectional Charging, V2G, V2H, V2L?

Can a bidirectional inverter charge a battery from an AC outlet?

With a bidirectional inverter, you get extra options regarding where your power comes from. In the other figure, you can see that bidirectional inverters allow you to charge your battery from your AC outlet. More about this later.

How do I use bidirectional charging?

Here are the four primary ways in which you can use bidirectional charging: 1. Vehicle to Grid (V2G) V2G is the most common bidirectional charging application; it allows the vehicle to send energy directly back into the grid. This is facilitated via a converter typically included in the charger, which changes the EV's DC energy into AC electricity.

What is a bidirectional inverter?

Unlike conventional inverters that only convert DC (direct current) to AC (alternating current), bidirectional inverters can also convert AC back to DC, allowing energy to be stored or fed back into the grid. This functionality is essential for applications like renewable energy systems, microgrids, and battery backup solutions.

What is a bidirectional EV charger?

A bidirectional charger is an advanced EV charger. It lets electricity flow two ways. Unlike a conventional unidirectional charger, a bidirectional charger is able to convert AC (alternating current) to DC (direct current) when charging a vehicle. Bidirectional EV chargers work like inverters.
