Honda lists our battery as a 60 Cell Lithium Ion pack. Nominal Voltage for Lithium Ion Batteries is 3.6v. (Most battery manufactures use 3.7v). Fully charged a Li-Ion cell is 4.2V, soft cell cut-off is 3.2V. What does this mean:
Fully charged pack 60x4.2V= 252V
Nominal (50%) = 60x3.7V (conservative number)= 222V
Discharged (Safe) 60x 3.2V= 192V.
The reason for my nerd-ing out was to try and figure out at what voltage were our Electric Motors operating at. I'd be willing to guess that our Insights EV propulsion system is rated at somewhere around 180V.
What I find totally confusing is that the NFPA Service Manual provided by Honda states our HV system is around 270V.
I got this bug in my head when reading about battery mods done to the second Gen insight (roughly 150V system).
Basing this information on our 10-unit battery gauge, each bar represents roughly a 6V change, operating range of 252-192V. If Honda used the 3.6V nominal calculation, then soft cell cut-off = 180V, each bar represents ~7.2V.
I'm sure that I'll expand on this when I get more information.
