Ferroamp launched its bidirectional charger, Ferroamp V2X, at the beginning of February.

With Ferroamp V2X, you can both charge and discharge electric cars with up to 20 kW. This allows property owners to use their electric car as a home battery and has the potential to make an important contribution to the stability of the power grid.

Note that Ferroamp V2X is a completely new innovation product in an immature market and therefore differs somewhat from other Ferroamp products:

• Since the product is not yet produced in volume, production costs are high, which is also reflected in the price level. To keep costs down at this early stage, you order the product directly from our development partner dc².
• A starting price of SEK 79,995 is listed on our website to indicate the expected price for the end customer.
  
• Car manufacturers have not yet implemented the ISO standard for V2G charging, so Ferroamp or dc² cannot guarantee that the discharge function will work with different brands.

How do you order Ferroamp V2X?

During this introductory phase, installers order Ferroamp V2X directly from Ferroamp’s partner DC Square AB (dc²). Email info@dcsquare.se.

Which cars can be charged with Ferroamp V2X?

Ferroamp V2X can charge all cars with a CCS connector for fast charging. Cars with 800 V architecture can also be charged.

Which cars can be discharged with Ferroamp V2X?

No special adaptation of an electric car is required for it to be discharged with Ferroamp V2X. However, the car’s software must not block discharging. In Ferroamp’s own tests, some car models interrupted or limited discharging after a short time.

As long as the car manufacturer has not implemented the ISO15118-20 standard protocol, there is a risk they may modify their software. Therefore, it cannot be guaranteed that a car model that works today will also work in the future. Similarly, a car model that does not allow discharging today may enable it in the future through a software update.

Successfully discharged in tests:

• BMW i7
• Hyundai Kona
• Kia Niro
• Polestar 2
• Polestar 4
• Tesla Model 3
• Tesla Model X
• Tesla Model Y
• Zeekr 001

Discharging blocked in tests:

• Audi e-tron

• Skoda Enyaq iV80

• VW ID.3

Will discharging the battery affect the car’s warranty?

Most car manufacturers have not stated their position on this. Ferroamp or DC Square (dc²) take no responsibility for any effect on the car’s warranty when using the discharge function.

How fast can you charge or discharge?

When the charger is connected to a Ferroamp system, the maximum charging power is the sum of available power from the grid, any solar production, and any stationary battery power. The charger’s maximum power is 20 kW and a current up to 50 A.

How can discharging (V2X) be used?

Discharging can currently be used, for example, to move energy from the car to a home battery, to shave peak loads, or to increase self-consumption of solar energy. This is configured via settings on the charger’s display. Discharging can also be controlled via the charger’s API. The V2X control software will be continuously developed as we see how different car manufacturers allow the use of car batteries.

For discharging control via OCPP from a charging operator/aggregator, the car must have implemented the ISO15118-20 standard protocol.

Can the charger be controlled from Ferroamp’s app or EnergyCloud web portal?

No. At present, the charger does not appear in EnergyCloud or the Ferroamp app and cannot be controlled from there. Charging monitoring can be done via the charger’s display, the car’s app, or an app from a charging operator via OCPP. Control configuration is done via the charger’s display.

Can I use the charger for ancillary services?

The charger’s response time is sufficient to participate in, for example, the FCR-D market, but it requires integration with an aggregator for control. No such integration exists today.

How do software updates work?

Due to developments from car manufacturers and in communication standards, we expect a great need for software updates during the first years. Software updates will be included in the price for the first two years.

Do I need an EnergyHub to use the charger?

Yes. Ferroamp V2X only works when connected to an EnergyHub.

Where can the charger be installed?

The charger has an IP43 protection rating and can be mounted on a wall outdoors or indoors using the supplied wall bracket. The charger is fan-cooled, so we do not recommend installation directly adjacent to living spaces.

How is the charger connected?

The charger is connected with a 3G6 cable to the DC distribution in the Ferroamp system. Maximum fuse: 32 A. An Ethernet cable must also be connected to the same local network as the EnergyHub.

When will the charger be delivered?

The first deliveries are planned for June 2025 and will then be delivered in the order in which pre-orders are received.

Who manufactures the charger?

The charger is manufactured in Sweden by Ferroamp’s partner DC Square AB (dc²).

Where can I get support?

Support for the charger is provided by DC Square AB (dc²): info@dcsquare.se
