Ford and Resideo want to help lower your energy bills with EV-Home Power Partnership

Energy bills too high? Try a Ford F150 lightning

You may have heard of V2H (vehicle-to-home) power transfer. The most commonly touted benefit is accessing energy stored in an EV battery as a backup power source during power outages. Further examples of connecting homes and vehicles to manage energy availability, usage, and cost are conceptually interesting. However, the logistics of making it all work have been out of reach. Ford and Resideo Technologies recently announced a collaboration to study how consumers could benefit from V2H connections.

The joint project is called the EV-Home Power Partnership. Resideo and Ford will explore V2H home energy management, beginning with home heating and cooling, which is often the most costly category of home energy use. With Ford’s Intelligent Backup Technology, the Ford F-150 Lightning EV is ready for V2H. Resideo manufactures connected smart home monitoring and control devices, including smart thermostats under the Honeywell Home brand.

How can EV battery storage help manage home energy?

Studies vary, but 5% to 15% of  U.S. households have backup generators for electrical power during outages. With Ford’s Intelligent Backup Technology, an F-150 Lightning with a fully charged battery could theoretically power your home for two to three days. This technology only works if the truck is home and the battery has a fair amount of charge remaining. If an outage lasts longer than a few days, you have a cold house and a truck you can’t drive. However, according to the U.S. Department of Energy, the average home and business will lose power for about seven hours yearly.

Using an EV as a backup power source has additional advantages over a conventional gasoline or propane-powered generator, including cleaner energy generation and less noisy operation, so you won’t annoy your neighbors when you keep a generator running all night.

With a managed home and EV connection, consumers can save on energy costs in several ways and avoid the expense of installing a home generator. If energy costs vary during high-use periods, running your home electrical system with power from an EV rather than the electrical grid is a saving, especially if you charge the EV at night or when energy from the grid is the least expensive.

Resideo and Ford will simulate V2H energy management

The initial focus of the EV-Home Power Partnership is to evaluate the extent of energy savings using bi-directional EV charging and Resideo smart thermostats. The study will measure the effectiveness of automating home heating and cooling using electricity supplier Time-of-Use (TOU) rate structures. The study will also explore integrating renewable energy from home solar energy collection systems with the V2H connection.

As EVs with bi-directional charging become more common along with the energy management software to optimize the integration, the tantalizing potential of whole-home renewable energy systems that include EVs running effectively off the grid comes closer to reality.

How to care for your EV battery and reduce range anxiety
Protect your investment with these handy EV battery care tips
ev charging in sunny weather

Electric vehicle batteries can be the source of a lot of anxiety -- most of which centers on their storage capacity. This can include range anxiety, and when a battery's performance degrades past a certain point, EV battery replacement costs.

There are also environmental concerns to consider. When your vehicle's juice box does eventually kick the bucket, EV battery recycling is an option and one that is becoming more and more efficient as time goes on. But with proper EV battery care, you can fend off the lithium reaper and keep your car's original power supply in place for years longer than it otherwise would be.

GM's upcoming EVs to provide power backup during outages
2024 Silverado EV RST

General Motors plans to electrify at least 50% of its entire lineup by 2030 to meet the EV adoption target set up by the U.S. government. Its most popular EV model is the Chevy Bolt, but GM announced it will be discontinued by the end of 2023. With the Chevy Bolt shelved, GM will focus its resources on producing its Ultium-based EVs models that will start rolling out by the end of this year.

The 2024 Chevy Blazer EV is expected to be delivered this summer, while the 2024 Chevy Silverado EV and 2024 Chevy Equinox EV will come out later in the fall. But to stay ahead of the competition and match up with Tesla, GM needs more than its reputable brand to convince potential customers. Barely two months after it updated the range of the Chevy Silverado EV to 450 miles, GM says its upcoming EV models will be able to back up your home during a power outage. This will be a big move that will roll the ball back to its competitors to catch up.

In 2021, President Biden's administration announced an ambitious plan to have 50% of all vehicles sold in the U.S. by 2030 to be zero-emission vehicles. As part of the plan, the government introduced the federal tax credit, and it's investing billions of dollars to advance charging infrastructure, battery components, and clean transportation technology. Popular automakers such as Ford, General Motors, Stellantis, BMW, and Volkswagen welcomed the government's plan and pledged that 50% of their lineups will be electric vehicles by 2030.
