Ford is preparing to revolutionize the cost of adopting electric vehicles as a source for home power generation with its upcoming electric truck, "Fathom," priced under $30,000 and scheduled for release in 2027. The truck features an innovative bidirectional charging system that completely eliminates the need to purchase expensive external power inverters typically mounted on walls, paving the way for lower overall costs for backup and home energy systems.
The new system's architecture is based on Ford's Universal EV Platform, leveraging technology developed by the company following its acquisition of the startup Auto Motive Power in 2023. Instead of relying on an independent external inverter, Ford has integrated the inverter unit directly into the E-box, which is one of the five main modules in the truck. This contributes to reducing the number of parts and lowering costs significantly, extending to home charging equipment as well.
Usage Options and Home Energy Management
The new system will allow users to utilize the truck's battery in two main ways:
- Home Power Management: Enables owners to charge the truck during off-peak electricity tariff times, then use the stored energy inside the home during peak consumption and high-price periods, via a new Home Power Station that Ford expects to cost half the price of first-generation bidirectional charging devices.
- Home Backup Power: Allows for keeping home appliances running during power outages. This feature requires the use of the Home Power Station along with a Home Backup Panel, equipment that Ford estimates will be at least 60% cheaper compared to the previous generation.
Early Coordination with Utility Companies and Standard Technologies
In addition to reducing hardware costs, the readiness of electrical utility grids poses a major challenge when dealing with thousands of vehicles pumping reverse power. To solve this issue, Ford formed a working group last July including companies such as American Electric Power, BC Hydro, Consumers Energy, Exelon, and Pacific Gas and Electric, with the goal of simplifying procedures for connecting vehicles to utility grids before the Fathom truck is launched next year.
The group is working to update utility procedures to comply with modern bidirectional charging standards, to facilitate the participation of electric vehicle owners in Virtual Power Plants (VPP) that supply the power grid with energy during peak demand. The truck's system is designed to meet the requirements of safety standards (UL 1741) and grid interconnection standards (IEEE 1547), in addition to relying on communication technology (SAE J3068) to reduce charger costs.
What Does This Development Represent Practically?
Until now, some economy cars like the Chevrolet Bolt and Nissan Leaf have offered bidirectional power solutions, but they typically require external power equipment from independent companies or connection devices with limited capabilities. In contrast, Ford offers an integrated package capable of providing more than 10 kW of AC power to the home without an external inverter, making the integration of home energy storage practical and low-cost.
However, some questions and limitations remain open; Ford has not yet announced the final prices for both the Home Power Station and the Home Backup Panel, and actual installation costs vary from one home to another, in addition to the need to update utility company regulations to encourage the adoption of this technology on a large scale.
