DESCRIPTION
Model BDI is an inexpensive, easy to install Battery Discharge Indicator (BDI). It is completely solid state and provides a reliable, accurate, and easy to read display of battery state-of-charge.
APPLICATION
This battery discharge indicator is ideal for golf cars, hunting buggies, commercial leaning equipment, mobility aids, electric bicycles, and similar equipment.
FEATURES
•Higher integrated circuits for long-life reliability.
• A 10-bar high light LED displays the state of charge successively, bar by bar.
• At 70% depth of discharge, a flashing LED signals an “energy reserve” alert.
• At 80%, alternately flashing LEDs provides an “empty” status warning.
• It is compact and easy to install.
• Recognizes improperly charged battery.
•Key switch activated LED display (state-of-charge is monitored as long as the BDI is connected to battery).
• Lens Material: Plastic
• Case Material: ABS KJW, Black
RESET METHODS
• Open Circuit Reset (OCR).
Upon reconnection of a battery, the BDI will reset to the full status if it meas¬ures 2.09 volts/cell or higher.
• Battery Charging Reset (BCR)
During charging, the BDI will light LED bar by bar according to the increased battery capacity, the BDI will reset to the full state when the BDI meas¬ures the voltage of per cell up to 2.35 volts or higher.
OPTIONS
Pin 3 is the collector of a triode without high drive ability. Pin 3 will output a pulse (Note.1) voltage at 80% discharge of battery. 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.
(Note.1: Output Saturation Voltage: 300 mV (Type) at 10 mA; Maximum VCE is 40V; Frequency is 1Hz.)
SPECIFICATIONS
• System voltages: 12V, 24V, 36V, 48V, 72V
• Operating voltage: ±25% of normal voltage
• Operating temperature: – 20°C to +75°C
• Storage temperature: – 40°C to +90°C
• Shock & Vibration: Meets SAE J 1378
