Some pictures of Renault project




General picture of the workshop:


FEVT workshop. The project Clio at the front.




Here she has got some more cover and register plates:


The car has been registered in Finland and built ready for test driving




View of her backside:


The batteries in the prototype are placed in the trunk for
easy access.There are 34 200 Ah cells
for 122 V nominal voltage. The blue horizontal stripes are plastic straps that
hold the battery units together. Each unit has 3 or 4 cells. The battery units
have end plates made of steel. The ’attache case’ to the left of the batteries
is a (very home-made) box for the contactor and fuse.





Renault has arrived to my home yard.





View under the hood from the left side. The charger is gone. The
radiator is gone. Also the gasoline heater is gone. The black cap and
'bottle' (where the radiator used to be) is the electric heater. The
messy red and blue wiring are the temporary heater connections, they
will be finalized later.





View under the hood from the right side. The main contactor is placed
where the charger used to be.





A box was built for the batteries. It is closed from below and opens
to the trunk from its upper part. The box houses 28 lithium cells. The
remaining six cells are placed on both sides of the trunk, three on
each side.





The trunk. A new inner structure was built to carry and hide the
electronics and the lithium cells. It also covers the opening that was
cut in the floor of the trunk.
The new charger is seen in the middle, flanked by two cooling fans for
the electronics. The BMS and other electronics are fixed on the other
side of the trunk wall, in the space between the trunk and the back
rest of the back seat.





Sanctum sanctorum.
The devices behind the back seat. From the left of the picture to the right:
The white box with blue stripes at the utmost left: lithium cell no.
3. Above it, fixed to the cell posts is the cell-individual BMS device.
It carries the cell-individual charger and the measuring electronics
for the voltage and temperature.
The big device with the green PCB: DC/DC-converter for the individual
cell chargers.
Small PCB below it: Battery current measuring shunt with electronics.
A square box with the white cover and the grey sihouette of a fruit:
BMS control computer (Mac mini).
Black box below it: Main switch and the fuse.
The metal thingy with many holes: DC/DC-converter for the individual
cell measurement circuits.
The white box with blue stripes at the utmost right: lithium cell no.
