EVI200 Inverter

EVI200 control board

This page relates to how best hook up a surplus SKiiP module to an EV, using a STM32F103VBH6.

The SKiiP came with

Case
High current stuff (caps, bus bar etc.)
70pin vehicle loom adaptor (AMP/Tyco 1-962-526-1) AMP site
Interface board (aux power supplies, drivers, buffers etc.)
DSP board (Tricore DSP)

Q.1 How much of the existing packaging that came with the SKiiP should be reused?

(Ed)

No objections with case + high current stuff.
The DSP is toast meaning the interface board will then require massive rework.
The loom connector is technically good IMO, but looks like it will be a pain for EV enthusiasts to source.

At the moment the plug gets a tick, the board gets a cross. For the existing users the connector can be salvaged to minimise loom rework. One new board to be designed/built to take SKiip or SKAI, STM32 and AMP plug, with ample headers and screw holes for future add ons/modifications.

Control Board Analysis

The board uses internal layers for routing so modifications will be very difficult.

I'll try to add datasheets collected thus far. Well, I started, but probably isn't good for bandwidth, for the moment here is a list of components. I'll find the links again later.

B82790S513 EPCOS Data and Signal Choke - near the CAN transceiver for some reason. Will dig further later
LTC3780 DC-DC converter - two of these, one large one, bulk of the caps etc, guessing for loom supply, one smaller for guessing SKiiP supply (1A 15/24V)
MAX232A RS232 Driver - next to the programming header (unsurprisingly)
MAX1044 Voltage doubler-inverter - mixed in with the Opamps - maybe for -ve temperature reading and -ve current reading
MC74HCT00 Quad NAND Gate - near the ISO9141 driver chip.
MC14504 Hex Level Shifter - buffers the 5V logic to 15V for the SKiiP 1H, 1L, 2H, 2L, 3H, 3L = 6 to shift. haven't traced but seems a good guess
MC33199 ISO9141 Serial Link Driver NOT FOR NEW DESIGN - but still manufactured. For interfacing with OBD-II style tools. (Perhaps it reports rpm = 0?)
OP27G Low Noise Op Amp - quite a few of these - 7, near the DSP header. Analog signals perhaps, current, bus voltage, temperature dc/dc volts at a guess.
PCA82C250 CAN Transceiver - doesn't seem connected to the 70pin plug, but to a separate header?
L9386 Dual Low Side Driver - drives the contactors (main and precharge, there are 4 so up to 8 outputs)
