Home Energy Storage and Electric Cars

The federal target for shares of electric vehicle sales is 50% by 2030. As electric cars become more popular, there will be more pressure on the already overwhelmed grid, since more electric vehicles (EVs) need to be charged. How can installing a home energy storage system help this situation?

Charging electric cars at the off-peak rate

Most EV owners would prefer to charge their cars during off-peak hours, which is usually after midnight. However, when more people do so, off-peak hours will become peak hours as increased demand will increase grid energy costs.

With home energy storage, excess solar energy can be stored and used to charge electric cars, reducing the supply pressure of the grid and removing the household’s need to charge the EV from the grid. That will relieve demand on a stressed grid and can save electricity bills for homeowners.

Charging EVs at the peak rate

Even though most owners would charge electric cars during off-peak rate hours, there could be emergencies when EVs need to be charged during peak rate hours. In this scenario, if there is home energy storage, homeowners could use the power stored in the batteries to charge the EVs, lowering utility costs. Sometimes the expense difference could reach as high as 70%.

How do EVs and home energy storage work together?

Electric cars can also be an energy source. As EV adoption becomes popular, there will be more pressure on the grid system during peak rate hours. The grid will be needing a better transmission and distribution system to be able to handle the power supply demands. Electric cars, as well as home energy storage, will both be good options for power transmission and distribution.

Solar panels can charge both electric cars and home energy storage. Homeowners can store and use solar energy to power the house and EV as needed, reducing the power demand from the grid system, and lowering electricity bills for themselves.

Franklin Home Power

Franklin Home Power (FHP) is a whole-home energy management system, which can be a good choice for homeowners with electric vehicles to increase home energy efficiency.

The heart of the FHP system is two components: aGate and aPower.

The aGate is an intelligent home energy management center that integrates solar, grid, energy storage, generator, and household loads including EV chargers, and manages them to optimize consistent energy supply, providing rapid backup in case of grid outages.

The aPower is a 13.6 kWh AC-coupled battery with a built-in inverter that automatically transfers between DC and AC current. It uses extremely safe LFP cells and can stack up to fifteen aPower batteries per aGate, which is able to supply sufficient power for charging EV cars.

Homeowners can use the FranklinWH app to remotely monitor and control their FHPs. There are backup, load shifting, and self-consumption modes to best suit homeowners’ needs, providing optimized energy and backup power to the home, lowering electricity bills, or living completely off-grid. The FHP has Smart Circuits with which homeowners can dynamically manage unique loads, such as EV chargers, through either preset schedules or manual control.
