Curtis Battery State-of-Charge (BSOC) Instrumentation model 906 for use in electrically powered vehicles

Curtis offers the widest range of Battery State-of-Charge (BSOC) instruments in the industry and continues to develop new algorithms to improve accuracy as well methods of measuring the state-of-charge of other battery chemistries and alternative fuel sources. 

Model 906 is an inexpensive, one piece, easy to install battery fuel gauge. It is completely solid state and provides a reliable, accurate, and easy to read display of battery state-of-charge. Model 906 is available in six panel mount packages and a printed circuit board mounted module for custom dash panel applications.

906

This battery fuel gauge features Curtis patented technology and is ideal for golf cars, commercial cleaning equipment, mobility aids, electric bicycles, electric marine motors, medical devices, and similar equipment.

• All principal circuits are integrated in a single chip for
long-life reliability.
• A 10-bar LED displays the state-of-charge successively,
bar by bar, from full to empty.
• At 70% depth of discharge, a flashing LED signals an
“energy reserve” alert.
• At 80%, alternately flashing LEDs provides an “empty”
status warning.
• Model 906 is compact and easily installed in panel cutouts
as small as 36.8 X 24.1 mm, with as little as 35 mm
behind panel clearance needed, see dimensions of various
case styles.

• Recognizes improperly charged battery.
• Keyswitch activated LED display (state-of-charge is monitored
as long as 906 is connected to battery).
• Memory allows gauge to recall state-of-charge whenever
battery is disconnected.
• Three possible reset methods:
1. Open Circuit Reset (OCR): Upon reconnection of a
battery the gauge will reset if it measures 2.09 volts/
cell or higher (example “B” profile) (for units with
memory option).
2. High Voltage Reset (HVR): Gauge must measure
>2.35 volts per cell for 6 continuous minutes during
charging (example “B” profile).
3. Charge Tracking Reset (CTR): Display tracks charge
level during opportunity charging (requires gauge to
be connected to battery when charging).

OPTIONS
• The Output Signal option causes the voltage on pin 3 to
drop from 5 to 0 volts at 80% discharge. It can be used to
signal another component or to allow for the disabling of
a specified vehicle function, insuring against abusive deep
discharge conditions. The Output Signal can also be used
to drive the Curtis 1178 Relay Module.
• Special models and custom panels are available.
