Honda Smart Home US

As demonstrated in Honda Smart Home US, distributed solar energy and plug-in electric vehicles can join forces to provide zero carbon living and mobility in an amazing way. As more and more EVs and houses fitted with solar panels come online, however, new challenges are presented to electric grid operators. We visited the California ISO (CAISO), which maintains reliability in one of the largest and most modern power grids in the world, to discuss these challenges and the way that Honda’s HEMS solves them.

In related news, we recently joined forces with major utilities and automakers to standardize vehicle-grid communications.

The Honda-designed Home Energy Management System (HEMS) located in the garage is a hardware and software system that monitors, controls and optimizes electrical generation and consumption throughout the home’s microgrid. The 10kWh energy storage system (dark box to the right) uses the same lithium-ion cells that are found in the Honda Fit EV. Our HEMS stores solar energy generated during the day for use at night, when household demand typically peaks and electric vehicles are usually charged.  It is also capable of “listening" to the grid to ensure we only draw power at the most carbon-efficient times.  

Designing Spaces, which airs on Lifetime, visited us in Davis a few weeks ago. Here’s part one of the episode. 

Honda’s experimental home energy management system (HEMSx) monitors, controls and optimizes electrical generation and consumption throughout the Honda Smart Home’s microgrid. A 10kWh battery energy storage system in the garage, using the same lithium-ion cells that are used in the Fit EV, allows stored solar energy to be used at night, when household demand typically peaks and electric vehicles are usually charged. 

Honda’s home energy management system (HEMS) is a proprietary hardware and software system that monitors, controls and optimizes electrical generation and consumption throughout the home’s microgrid. A 10kWh battery energy storage system in the garage, using the same lithium-ion cells that are used in the Honda Fit EV, allows stored solar energy to be used at night, when household demand typically peaks and electric vehicles are usually charged. Honda’s HEMS leverages the battery to balance, shift and buffer loads to minimize the home’s impact to the electric grid. The system will also enable Honda to evaluate the second life, or re-use, of EV batteries in grid applications, home-to-grid (H2G) connectivity and other concepts. The technical animation above demonstrates how Honda’s HEMS works.
