Bricklin EV-1 Owner's Manual
The transmission also provides a “Park” position that locks the transmission. Since the motors
normally spin freely, parking on a hill without a transmission is not easily accomplished unless there is
a parking brake. The original Bricklin SV-1 utilized a mechanical drive speedometer driven by a cable
to the transmission. This same cable is used and makes it quite simple to maintain the original
speedometer. It is also possible to use a GPS speedometer.

Gauges & Instrumentation
An electric vehicle driver should be aware of what the vehicle is doing in a
similar manner to the original ICE vehicle. This requires the replacement or
addition of some gauges. An oil pressure gauge is no longer required, but
a gauge to display amperage the motor is receiving is quite useful. Though
the engine coolant temperature is no longer needed, it may be useful to
monitor the coolant temperature of the motor controller and/or battery
charger. The WarP Motors also provide a thermistor to allow monitoring
the internal motor temperature. The existing fuel gauge can be converted
using a Coulomb counting device so that the driver has a visual display of
the fuel available (battery State Of Charge SOC).
Torque – Android App
A tachometer should be connected so that the motor RPMs may be monitored.
Other gauges that may be useful are: motor voltage, battery pack voltage, motor amperage, and
battery pack amperage. Since we are trying to preserve the original instrumentation cluster while
adding the new instrumentation needed we have chosen to use an Android based tablet display and
an application called “Torque”. Torque is a very versatile application that allows the Android tablet to
display various OBD-II information in a wide variety of displays, such as analog sweep gauge, digital
gauge, graphs, etc. If the Android device is GPS enabled, Torque can also display the GPS speed.
Torque can also be used to display (and record) RPMs or any data supplied by the WarP-Drive
Industrial Controller or PulsaR Power Distribution Unit.
