¶ EnPower Charger
It may be necessary to run a BridgeConnect with the twin canbus ports running in pass-through mode to provide ground isolation from the charger traction battery supply and WatchMon ground reference.
CAUTION: Example below has values shown for a demo LiFePO4 cell pack. Ensure you adopt values suitable to your application.
¶ Install communication cable to charger via CAN1 port on WatchMon.
¶ For newer WatchMon
Note: 120 Ohm resistor shares CANbus High and CANbus Low
¶ For Older Watchmon with 4 Pin CAN
¶ Install communication cable to EnPower charger wiring socket.
NB: Add 120ohm terminating resistor on charging lead.
¶ Configure Watchmon Toolkit Software
¶ 1. Integration Settings
Open the WatchMon Toolkit and navigate to the Integration Settings by clicking the Menu then Hardware and select Integration Tab.
Select Canbus protocol to "EnPowerCharger" and Save.
¶ 2. Charging Settings
On WatchMon Toolkit, navigate to Control Logic menu, then Charging tab.
Adjust the Charging Control Logic to suit the application.
Notes:
- Low power must be enabled.
- Cell Hi Cutout should be above the CellMon bypass voltage threshold as a safe guard target.
- Low power current should suit the bypass capability of CellMon.
- When the bypass current is above Initial, it will trigger the system to low power.
- When the bypass current for all cellmons is above Final, the system will complete charging cycle.
¶ 3. CellMon Settings
Navigate to Hardware, then CellMon tab.
Adjust the CellMon Bypass Voltage to suit the application.
Note: Make sure to "Device Sync" the changes to the CellMons.
¶ 4. Remote Settings
Navigate to the Remote tab on the Control Logic screen.
¶ Adjust the remote charging target to suit the application.
Notes:
- Scaling must be 10, for both voltage and current.
- Low power must be enabled on charging tab.
- Low power current should suit the bypass capability of CellMon.
- Charger voltage target needs to be sufficient for all cells to reach bypass threshold.
¶ 5. Live Stats
Navigate to Telemetry, then Live Stats to observe system operation.
