Charger-unit costs can be as low as $400 for home charge points, $2,400 for public AC level 2 charge points, and more than $30,000 for lower-end—50 to 150 kilowatts (kW)—DCFC points. When combined, however, the following additional costs can represent a majority of the total up-front costs of an EV-charging solution:
The second, thermal energy storage (TES) or building thermal mass as a battery, consists in storing thermal energy in the building thermal mass, typically by pre-heating the building interior. The energy stored in the TES system is then released to meet short to medium term space heating energy demand.
