An anonymous reader quotes a report from Electrek: Siemens and Philadelphia-based ConnectDER have partnered to launch a simple and revolutionary home EV charger connector. Previously, homeowners who wanted to install EV chargers may have had to spend thousands of dollars to modify their home’s electrical panel. This new proprietary plug-in adapter will eliminate that cost and allow installation and connection in minutes. ConnectDER manufactures meter collars that are installed between the home meter and the meter outlet to create a single plug-and-play access point for installing Distributed Energy Resources (DER). In other words, collars easily add new electrical utility capacity for things like solar power and energy storage. From now on, ConnectDER will exclusively manufacture and supply Siemens proprietary plug-in EV charger adapter.
The new adapter will allow electric car owners to charge their electric vehicles by connecting the chargers directly through the meter socket, which is on every home. It provides more usable capacity by monitoring the total load and controlling the EV circuit to ensure that the total rated capacity is within the limit. Bypassing the electrical panel reduces the cost of installing the EV charger by approximately 60-80% because electrical panel upgrades are not required. […] Nearly half of US home electrical panels would previously have needed upgrades to fit a typical Level 2 charger, typically a 7-11kW device that draws 40-60 amps on a 240V line A Siemens spokesperson said the company is still finalizing pricing, but “it will only be a fraction of the cost of a service panel upgrade or other modifications often required to perform a loader. Also, in some cases, the cost may be entirely borne by utility programs.”
The adapters themselves are expected to be available by Q1 2023.
