Smart-grid integration allows vehicles to seamlessly authenticate on the network through Plug and Charge automated payments for EV charging, coordinating the timing and direction of energy to and from the grid and home. Smart-grid charging applications supported by the CCS standard allows users the flexibility to choose optimal charging times and extract energy from their EVs as needed, supporting the growing need for EV charging while minimizing peakload power generation and distribution requirements.

The QCA7006AQ is based on the vendor’s existing QCA700X family of products, which have been widely adopted in EVon-board charging units and charging stations. The device is compliantwith the Home Plug Green PHY (HPGP) specification,  the leading specification for implementing Vehicle-to-Grid (V2G) systems.

The new product is Qualcomms’ first QCA700XPLC device designed to support an Ethernet digital interface and that is qualified to support an ambient operating temperature range of-40°C to +105°C (AEC-Q100 Automotive Grade 2). As an optional feature, the QCA7006AQalso supports Home Plug Audio Video (HPAV) streaming at PHY rate exceeding 200 Mbps, allowing EV customers an alternate wired data connection to the cloud through the charging station. The introduction of the Ethernet digital interface, in addition to Serial Peripheral Interface (SPI), the AEC-Q100 Grade 2 compliance, and the HPAV operation mode, supports expanded design flexibility for future devices.

The QCA7006AQ is planned to be available for production by early Q4 2022; samples are available today.
