|Location||Bristol, England United Kingdom map|
|Vehicle||1988 CityCom City El |
This little City El was owned by Fifes Bananas before I
brought it. It only had 712 miles on the clock when I brought
even though it was eight years old by this time!
|Motor||Thrige-Titan Compound Wound DC|
2.5 KW continuous
|Controller||Curtis 1204x 5203|
36-48 V controller with Max current of 275 A continuous.
|Batteries||12 Thunder Sky LCP100AH, 3.60 Volt, Lithium-Ion|
|System Voltage||43 Volts|
OEM CityCom Charger, modified to be controlled by BMS unit
from Reap Systems.
|DC/DC Converter|| |
OEM CityCom DC/DC converter.
|Top Speed||45 MPH (72 KPH)|
Speed limited to 45 MPH by controller current limit and
resistor in field windings. It will go faster downhill though
(The fastest I've been is 52mph, but that gets scary!)
|Acceleration||0-30mph in 6.5 seconds with 200Amps at the controller. |
0-30 in 10 seconds with stock 120 Amp limit at the
Faster than standard with lighter batteries and 43V instead
|Range||50 Miles (80 Kilometers)|
With careful driving (at 30 mph) 50 miles are possible. In
my City, which has major traffic congestion and very steep
hills I'm getting about 30-35 miles on a daily basis with
heavy acceleration up to 40mph and frequent stopping.
|Watt Hours/Mile||100 Wh/Mile |
Taken after a journey of 24.8 miles on wet roads with an
average speed of 30 mph. The BMS display showed the
battery half-depleted. An energy meter on recharge showed
2.5KWH to recharge the pack.
|Seating Capacity||1 Adult|
|Curb Weight||450 Pounds (204 Kilograms)|
The car has recently been lightened by over 140 lbs by
replacing the stock lead acid batteries with Thundersky
|Conversion Time||One week (approx. 40 hours) to convert from standard |
lead acid to Lithium Ion. The longest part of the process
was making the custom wiring loom with over fifty sense
wires to the BMS unit, modifying the stock City El charger
and installing new loom in the car.
|Conversion Cost||£2000GBP for lithium Ion BMS plus batteries.|
|I would urge anyone who is considering Lithium Ion batteries in their EV to try out an |
someone has put lithium in. The difference to performance over lead acid for
small vehicles is truly amazing.
I've had to recently replace the four worst cells (with high internal resistance) with
TS100LCP cells. The performance is back to normal now and I can accelerate pretty
You can see the conversion from Lead to Lithium at my website (see above).
**** Update, June 2008****
Due to work I'm unable to use the City El as my daily transport. Instead I'm working
on a PHEV conversion to my Toyota Prius.
