Civic HEV IMA Battery
Do not try to do anything you see in this video unless you are already a
trained professional. This battery pack has the potential to kill you and
cause property damage in a number of ways.
Honda and Panasonic did an excellent job in this well thought out design
and build of a battery pack. This just a basic overview of some of the
clever things that were done in this gen-1 2004 model year Honda Civic HEV
IMA battery pack. The pack has 120 cells that are welded into 20 subpack
sticks of 6 cells each. The cells were rated by Panasonic for 6Ah. The
Battery pack was used to power the ~15 kW IMA motor in the Gen-1 Civic HEV
Considering that this battery technology is from the late 1990's it has
impressive performance for its time, especially the power Watts per unit of
vehicle space ... W / L.
About ~40 Wh / kg ... ~119 Wh / L ... ~691 W / kg ... ~2,232 W / L.
It was discharged at up to a ~18.8C rate in the Gen-1 HEV Civic.
Of course battery technology has today come a long way sense the late
1990's... but that's a different topic.
