Infineon and Delta have developed a three-in-one-system that integrates solar, energy storage and charging of electric vehicles.
Thanks to bidirectional inverters, the electric car is not only charged, but can also be used as a buffer storage or as household emergency backup power.
Bidirectional energy flows could also be used to realise new vehicle-to-home (V2H) and vehicle-to-grid (V2G) solutions.
“To make a sustainable contribution to decarbonization, we must think electromobility holistically: from green power generation to a stable, efficient grid infrastructure to storage and consumption,” says Infineon’s Peter Wawer, “with our solutions for bidirectional charging, the electric car can be charged inexpensively with solar power at home and also serves as a buffer storage.”
A single-family home can consume an average of 10-15 kWh of energy per day.
A fully charged car battery with a capacity of 30 to 100 kWh could therefore theoretically bridge a few days as an emergency power solution.
Homeowners thus secure inexpensive electricity as well as more independence in power supply.
The new system provided by Delta allows a maximum continuous current of 34 A and achieves peak efficiencies of more than 97.5%.
