Nov 2016 added another 10kW of Chevy volt
batteries, for a total of 24kWh

14 kWh of 16kWh Chevy Volt Pack installed Oct.
2015.

Pack is three, 100lbs. modules of 28 cells
each in plastic tool boxes. Each module is
about 4.5 kWh maximum capacity.

28 Cells/module Lithium Maganese Oxide x 3
modules in parallel. Each module fused w/175A
fuse.

Each cell is 45Ah. 45Ah x 3 modules x 106V =
14.3 kWh Maximum theoretic capacity, but only
use 66% of that in real world driving to
protect battery cycle life. Run pack from 112
Volts to 100 Volts (4.0V-3.57V per cell)

See www.schultzengineering.us/delta-11-12.htm
for details of how volt batteries was chopped
up for use in motorcycles AND in electric car
(modular, quick swap).

3-11-16 Demonstrated that 7,000 Wh is max I
can get out of batteries during a 111V to 98V
discharge run. This is Batt. pack 1.
System Voltage106 Volts
Charger
76% Average Recharge Efficiency (kWh as
measured by Cycle Analyst during trip divided
by Recharge kWh from the wall measured by
Kill-A-Watt meter).

Enginer Brand Chinese Origin. Final output
less than pack max. voltage so no BMS/cutoff
required. Chargers charge and then quit
before needing to be shut off.

4 chargers x 1200W each = 4800W 2 of 4
chargers are 110/220V switchable, so I
can charge from J1772 when needed.

Re-Charge time with all four chargers about 13
mph.
HeaterNovember 28, 2015 Installed 1300 Watt PTC
heater from EVTV - better, but need to test
defrosting ability with snow.

November 15, 2015 300 Watt "Back Seat Heater"
was not enough to make a dent in cold.

Pre-Heat with 110VAC 1200 watt heater on
timer. If car interior is pre-heated before a
ride stays warm to destination. E.G. Start
at 90 degrees F, 10 miles later it's still
over 70 degrees F even when it's 30-40 degrees
outdoors. Also, helps with keeping window
clear of interior fogging.

-Temperature gage inside one battery box to
monitor battery temperature
-Use Factory Speedometer for velocity and

Acceleration0-60 in 28 seconds.

but, keeps up with traffic if draw 30kW when
accelerating with traffic.
I drive using mostly 2nd and 4th gear.

I take off in 2nd gear to 20-25mph, then shift
to 4th 20-69 mph. It saves on shifting
effort and time. Car accelerates faster than
normal traffic 0-25 mph and slower than normal
traffic 25-69mph.
Range50 Miles (80 Kilometers)
Solid 50 mile range Highway and/or City
driving.

30 miles on Battery Pack #1 and 20 miles on
Battery Pack #2.

Have driven 58 miles on one charge (but I try
to not go below 100 volts at rest for each 28
cell battery).

On flat road takes this energy to go this

November 2016: Now 2350 after adding another
200# of batteries for 20 more miles range

2,150# includes 2 lead acid batteries that run
the 12Volt system, 4 chargers (at 5# each), 2
extension cords (10#), scooter (7#), charging
adapters including J1772 (6.5#)

Has 380 lbs of batteries (300 Lithium + 80
Lead Acid) + 60 lbs of charging equipment.

Has about 40 Hp peak in operation so that is
54 lbs/Hp.

With a Tesla Drive Train (416 Hp, 443Ft-lbs)
it would approach 5.16 lbs/Hp 4.8 lbs/ft-lbs).
Compare this to the 2015 Supercharged ZO6

Additional FeaturesMouse nest smell from being stored. - Almost gone after lots of
cleaning interior - Ozone treatment helped a lot.

Electric Vacuum Pump for Brakes - Runs on 12 Volt system. Made car
stop - don't know how I drove it before. Very nice. Added December
12, 2015.

Use clutch pedal switch to pre-charge controller capacitors before
switching on the main contactor.
