HAZARDOUS HIGH VOLTAGE
This equipment is connected to hazardous line voltages. Exercise
proper caution when connecting the sensors and voltage leads.
Ensure that the system is enclosed in a protective casing.
GENERAL DESCRIPTION
The AD-ACEVSE22KWZ-KIT is a reference design for the metrolo-
gy 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 ul-
tralow-power ARM
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 transi-
tion 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.
