I have an electric Civic with most of a Leaf pack set up as 330v. I do not have a charger or BMS currently and am looking into options.
The motor is a Kostov 11" rated at 144v however the guy I bought it from said it ran fine at 330v. This would lead me to believe it would be ok to run any voltage in between those?
I live about 20 miles from town. My starting goal for this car would just be to get to town where I could plug in. I am in the process of removing and inspecting all the batteries. When I reinstall them I am considering putting in just 20 modules for the nominal 144v. At ~10kwh storage this should get me to town and then some. In theory. Luckily the car has a tow bar installed.
If the motor will work at least up to 330v it seems like I could then add modules until I got the range I wanted while keeping the weight down as much as possible. As long as I had a variable voltage charger (considering the Manzanita PFC20)
Then comes cell balancing. This is where I feel the most unclear. A computer taps voltage and temp of each module and takes control of charger on/off? But how a high voltage charger connected to the pack mains would give attention to an individual module eludes me. Or can the BMS actually dissipate power through the tap wires to let lower voltage cells "catch up" ?
For the 20 module idea it looks like an option would be 2x Manzanita MK3x12 Digital Lithium Regulator
Any info or advice would be appreciated!
