Product Details

The AD-ACEVSE22KWZ-KIT is a reference design for the metrology subsystem plus selected other features of a level 2, 7 kW to 22 kW AC electric vehicle supply equipment (EVSE). It includes the ADE9113 isolated Σ-Δ analog-to-digital converter (ADC) coupled with the ADE9178 metrology DSP to accurately measure energy delivered to an electric vehicle (EV). It includes the MAX32672 ultralow- power ARM® Cortex®-M4 processor, a cost-effective, highly integrated, and highly reliable 32-bit microcontroller to accumulate energy measurements and securely send it to a host for display. A charge control state machine is run on the microcontroller to transition through different charge states when a charging plug is inserted into an electric vehicle. The kit includes a flexible printed circuit (FPC) connector and LCD to read the energy measurements and state transitions during a charging cycle. The power input/output, control pilot (CP), and proximity pilot (PP) signals are exposed on connectors at the edge of the board. The energy delivered to the EV is measured as a voltage drop across shunts and a resistor ladder network, which makes it easy to set up the boards in the field.
