>2.35 volts per cell for 6 continuous minutes during High Voltage Reset (HVR): Gauge must measure.Open Circuit Reset (OCR): Upon reconnection of aīattery the gauge will reset if it measures 2.09 volts/Ĭell or higher (example “B” profile) (for units with.Memory allows gauge to recall state-of-charge whenever.Keyswitch activated LED display (state-of-charge is monitored.Model 906 is compact and easily installed in panel cutoutsĪs small as 36.8 X 24.1 mm, with as little as 35 mmīehind panel clearance needed, see dimensions of various.At 80%, alternately flashing LEDs provides an “empty”.At 70% depth of discharge, a flashing LED signals an.A 10-bar LED displays the state-of-charge successively,.All principal circuits are integrated in a single chip for.Operating voltage: +/–25% of nominal voltage.For more details, please see the 906 Meter Datasheet (PDF format). Special models and custom panels are available.Signal another component or to allow for the disabling ofĪ specified vehicle function, insuring against abusive deepĭischarge conditions. The Output Signal option causes the voltage on pin 3 toĭrop from 5 to 0 volts at 80% discharge.The IoT Cloud Dashboard will display the battery voltage along with the battery percentage in both the charging and discharging conditions. Packages and a printed circuit board mounted module for In this IoT-based Battery Monitoring System, we will use the NodeMCU ESP8266 board to send the battery status data to the Arduino IoT cloud. Model 906 is available in six panel mount It is completely solid state and providesĪ reliable, accurate, and easy to read display of battery Model 906 is an inexpensive, one piece, easy to installīattery fuel gauge. Typical model: 906T48HNDAO, 48V with CURTIS logo.
CURTIS 906 meter is a simple and effective BDI (battery discharge indicator). Used as battery charge / discharge meter, CURTIS 906 state-of-charge gauges are widely applied by golf cart and electric forklift makers.
If it doesn't - replace it.CURTIS 906 Series Battery Discharge Level Indicator Voltage options: 12V / 24V / 36V / 48V If the battery performs well, leave it alone. In short, don't worry abouth the battery eye. One cannot deduce a state of charge of a lead-acid battery by its open circuit voltage, other than to distinguish between completely depleted and somewhat charged. Less than 12.0V - battery depleted or badġ2.1.13.0 - battery MAYBE in some state of charge other than completely depleted.Ībove 13.1V - battery in some rare failure mode with voltage above normal, no good behavior expected.
The voltage of the battery (with no engine running) is pointless as well. in older battery) may be in another state. More elaborate systems management is also available: this includes monitoring. Whatever the indicator shows, it is immersed in one cell, others (esp. A clear display shows performance, consumption and available battery capacity. The level somewhat depends on the temperature, a hot battery may have somewhat higher level. A fully charged battery turn green only when shaked. The green color may be a matter of mixing the electrolyte. May need topping up with deionized water (but the battery is likely marketed as maintenance-free and hard to open, so no topping up possible). White (red on some brands): electrolyte is low. Green: electrolyte is dense enough (battery charged above some point) and high enough level.īlack (white on some brands): electrolyte is watered down (battery somewhat depleted) and still high enough level.
The only reason it exists is that is increases sales of new batteries.
