In 2012 Hurricane Sandy ravaged New York and left thousands without electricity. South Korea has had to shut down a couple of nuclear plants for safety checks, which could bring rolling blackouts. It only takes a couple of hours without electricity to realize how dependent you are on electricity. Bosch’s voltwerk, a storage unit for electricity, is part of getting off the grid, part of regulating the electrical infrastructure.
I’m so glad I don’t have an electric vehicle
It’s the first thing that pops up on my facebook page after a blackout. If you don’t have electricity you can’t charge your electric vehicle. You can buy solar panels that give you free electricity as long as the sun is shining, but the night is long and cold, and dark, without electricity.
Bosch’s slogan is “invented for life”, but Bosch’s slogan should be integrated with life. I talked with Eric Daniels, the regional President of Solar energy, Bosch North America. Bosch has installed an EV charging system using a charger from Eaton Corporation. The system connects Bosch solar panels to a charging unit to charge electric vehicles. These can be used in your garage or at car parks. Bosch can now take electricity and charge an electric vehicle whether there is a grid or not depending upon the design.
Bosch through its Voltwerk business unit, has developed a 5kwH storage unit that stores electricity for the home. If your home goes off grid, the storage unit allows you to continue to run loads that are in the home. Daniels likens the idea to a bathtub, or reservoir of energy.
If the electricity in my home goes out, I plug a generator into my home that runs on gasoline. The Bosch storage unit requires no fuel source, the only energy comes from the sun through the solar panels or from the utility if it is working. Daniels says to think of the solar panels as the generator
The next step in the integration of solar life is using the battery in the EV to power your home. If the reservoir becomes depleted of energy and there is electricity in your EV battery you will be able to hook your EV to the storage unit, pass that energy into the reservoir and electrify your home. The storage unit, aka reservoir, should be out, according to Mike Mansuetti, President, Robert Bosch LLC, in about a year. Bosch has not said when the EV to storage unit will be available.
