  1. Lithium Ion and VRLA BatterySafety Monitoring for Storageand Charging Jordan Allen University of Idaho ECE Department ECE Power Lab

  2. Outline • Overview • Controller • Temperature Sensor • Setup • Results • Conclusion • Future Work

  3. Overview The scope of this project is to provide remote access automated monitoring for the ECE Power Lab. An IP enabled controller will be used to monitor a temperature sensor at a select location of the lab and provide notification via email and/or relay triggering when monitoring conditions are out of the desired range.

  4. Controller • Barix BarioNet IP Enabled Programmable Controller • Built-in Web Server that is completely customizable • 2 Relay Outputs (5A @ 250VAC) • A Dallas 1-Wire interface that can support up to 50,1-Wire temperature sensors • Operating temperature:0 to 50°C / 32 to 104°F • Password protected

  5. Controller

  6. Controller SCHRACK PEO14005 PIC16F877A

  7. Controller [3]

  8. Temperature Sensor • Tamperproof SS Flat Plate 1-Wire Temperature Sensor • A DS18B20 digital sensor with 12-bit resolution • +/- 0.5°C accuracy over range of -10 to 85°C • Measures Temperatures from -55 to 125°C (-67 to 257°F) • A flat plate sized to fit a single gang box

  9. Temperature Sensor 1 – GND 2 – DQ (Data I/O 1-Wire interface pin) 3 – VDD DS18B20 [6] 1 2 3 Note: The 1-Wire interface pin (DQ) provides power to the device when used in parasite power mode. VDD must be grounded for operation in parasite power mode. [5]

  10. Temperature Sensor [2]

  11. Setup [4] [5]

  12. Setup

  13. Results • Challenges • IP configuration • SMTP setup • Email delay (1min. 50sec.) • Interpreting settings

  14. Results • Success • Confirmed proper operation of relay triggering when temperature is out of set range • Confirmed proper operation of email notification when temperature is out of set range

  15. Conclusion The BarioNet 100 has provided remote access automated temperature monitoring for the ECE Power Lab via email and/or relay triggering when monitoring conditions are out of the desired range.

  16. Future Work • Expand monitoring to include: • Two temperature sensors • One hydrogen sensor • One air quality sensor • Two vibration sensors
