I'm off to design a PCB to my inverter
Right now I have a high and a low voltage section and this is what I've included
Low Voltage:
Throttle Input - Current signal with broken wire detection
Tachometer Output - Optoisolated with 100mA Fuse. Goes into the cluster
Brake input - Throttle over-ride, hard regeneration and stop regeneration
e-Reverse input - Reverse gear switch input
Ignition power input - Electronics power
Ignition start input - To start the thing. Can also be done via RFID
12V battery monitoring - Voltage reading, DC-DC Power good signal
Battery indicator - Indicates when the DC-DC converter is not operational
Reverse light output - This drives the reverse bulbs and a buzzer
For the high voltage Side:
Battery voltage monitoring
Pre-Charge Control circuit (dedicated and on-board)
EVSE Communication
DC-DC Buck converter output (to 320V @ 1KW) and power output
Encoder Input (isolated)
Pre-Charge or IGBT output (With relay economizer, PWM, 2A, 500V, fused)
Optoisolated Fault inputs (2x)
AC-DC onBoard Power supply - Interlock for the inverter when charging, DC-DC control, Main Charger control.
OptoIsolated IGBT output - The gate drivers are in a separate PCB
Any suggestions on some stuff I should add?
