Discover CAN BUS Type-B Battery Discharge Indicator
INTRODUCTION
The Type-B Battery Discharge Indicator (BDI) communicates with Discover Lithium batteries over CAN Bus using the LYNK Port on LITHIUM PROFESSIONAL or AEBus Port on AES LiFePO4 Industrial batteries. The TYPE-B BDI displays warnings, charging status, and state-of-charge (SOC) using incremental LED SEGMENTS. The BDI device is plug and play, deriving both power and battery status directly from the LYNK Port or AEBus Port. The TYPE-B BDI will provide the aggregate SoC for up to 20 Discover Lithium Batteries. The Type-B BDI is rated IP 30, with an installed frontal rating of IP 65.
Compatible Batteries
- AES LiFePO4 Industrial Batteries: 12-48-6650, 12-36-6700, 14-24-2800, 14-36-3000, 14-48-3000
- LITHIUM PROFESSIONAL Batteries: DLP-GC2-12V, DLP-GC2-24V, DLP-GC2-36V, DLP-GC2-48V 2.0
INSTALLATION OPTIONS AND REQUIRED MATERIALS
The Type-B Battery is available as a head unit (950-0034) and used with AES LiFePO4 or LITHIUM PROFESSIONAL batteries. The installer must supply a cable of the appropriate length with a pinout and connector appropriate for either an AES LiFePO4 Industrial battery or a LITHIUM PROFESSIONAL battery. Refer to section 6.0 Battery Pinout Assignments for details on connectors and pinouts.
A kit (950-0039) that includes both the TYPE-B head unit (950-0034) and an LYNK NETWORK BDI 1.8M cable (790-0079) is available from Discover for installation with LITHIUM PROFESSIONAL batteries.
LED INDICATORS
Normal Operation
Only 1 LED will be on during regular operation.
| Position | Activity |
|
LED 1 |
Flash – State of Charge 0% to 9 %
Solid on – State of Charge range 10% to 19 % |
| LED 2 | Solid on – State of Charge range 20% to 29 % |
| LED 3 | Solid on – State of Charge range 30% to 39 % |
| LED 4 | Solid on – State of Charge range 40% to 49 % |
| LED 5 | Solid on – State of Charge range 50% to 59 % |
| LED 6 | Solid on – State of Charge range 60% to 69 % |
| LED 7 | Solid on – State of Charge range 70% to 79 % |
| LED 8 | Solid on – State of Charge range 80% to 89 % |
| LED 9 | Solid on – State of Charge range 90% to 94% |
| LED 10 | Solid on – State of Charge range 95% to 100% |
Charging Operation
The active State of Charge LED will slowly flash
Battery Protection Indication
When a connected battery has active protection (faults), LED 1 through LED 10 will all flash at the same time.
No Battery Detected
The LED interface will continuously cycle through all LEDs when the BDI-B is powered on, but no batteries are detected.
