Curtis Battery State-of-Charge Instrumentation model 803 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.  

Curtis Model 803 combines in one instrument a completely solid state battery discharge indicator, an LCD hour meter and lift lockout, housed in a 52mm case. Void of moving parts, this combination instrument is exceptionally reliable even in severe operating environments.

803

Curtis Model 803 is a combination gauge ideally suited for electrically powered vehicles.

‘Fuel’ Gauge Features
• Multicolor 10-bar LED displays state of charge (5 green,
3 yellow, 2 red LEDs).
• Flashing red LED signals “energy reserve” alarm at
70% discharged.
• Double flashing red LEDs signal “empty” alarm at
80% discharged.
• Normally closed relay opens at 80% discharge for lift lockout.
This unique holding relay will only lock out at the end of a
lift cycle.
• Recognizes improperly charged battery.
• Keyswitch activated LED display (Fuel gauge electronics are
energized as long as they remain connected to the battery).

• Wide range adjustable discharge profile.
• Dual reset methods in each gauge: Open Circuit Reset for
vehicles that exchange batteries and Charge Tracking Reset
for vehicles whose batteries remain connected to the gauge
during recharge.

Hour Meter Features
• Monitors use-time throughout the equipment’s lifespan.
• Records and displays up to 99,999.9 hours on its LCD, rolls
over and continues to count and display.
• Hour meter LCD remains on as long as battery is connected.
• Stores latest total in EEPROM nonvolatile memory, without
need of power.
• Operates and displays in temperatures from –40°C to +65°C
under harsh conditions of vibration, shock, moisture and dust.
