I will simulate a bidirectional ev battery charger afe and dab

Complete PLECS 5.0 simulation of an isolated, bidirectional EV battery charger (grid-to-battery and vehicle-to-grid), with fully discrete controllers in C-Script.

WHAT'S INCLUDED

Grid AFE rectifier: 230 Vrms / 50 Hz, 100 kW, 600 V DC link, 50 kHz, Min-Max PWM

Dual Active Bridge (DAB): SPS modulation, 1:1 HF transformer, 65 kW, galvanic isolation

Battery bank: 192s74p Panasonic NCR18650B, 691 V nominal, about 170 kWh, Shepherd model

CONTROL

Voltage-Oriented Control with SRF-PLL

dq current loops (2 kHz) with decoupling and anti-windup

DC-link voltage loop with reference prefilter

Battery EMS: CC/CV charging (80 A / 780 V), stops at 95% SoC, idle gate blocking

V2G mode: battery energy injected back into the grid

RESULTS

Unity power factor, sinusoidal grid currents

62 kW charging, about 91% grid-to-battery efficiency

About 93% efficiency in V2G mode

YOU GET

4 organized PLECS models (AFE, DAB+battery, full charger, charger with V2G)

Commented C-Script code and labeled scopes

Results obtained in simulation with ideal switches.
