  • Page 4: Safety Precautions

    Lynx Shunt VE.Can 1. Safety Precautions 1.1. Safety Warnings Lynx Distribution System Do not work on live busbars. Ensure that the busbar is unpowered by disconnecting all positive battery poles prior to removing the Lynx front cover. Work on batteries should be carried out by qualified personnel only. Observe the battery safety warnings as listed in the battery manual.

  • Page 5: Introduction

    2. Introduction 2.1. The Lynx Shunt VE.Can The Lynx Shunt VE.Can contains a positive and negative busbar, a battery monitor and a fuse holder for the main system fuse. It is part of the Lynx Distribution system. The Lynx Distributor has a power LED.

  • Page 6: Temperature Sensor

    • Lynx Distributor - A positive and negative busbar with 4 fused connections for batteries or DC equipment together with fuse monitoring. • Lynx Shunt VE.Can - A positive busbar with a space for a main system fuse and a negative busbar with a shunt for battery monitoring. It has VE.Can communication for monitoring and setup with a GX device.

  • Page 8: Main Fuse

    3.2. Main fuse The Lynx Shunt houses the main system fuse. The fuse is being monitored by the Lynx Shunt VE.Can and, if the fuse blows, the power LED turns red and an alarm message is sent to the GX device.

  • Page 9: Temperature Sensor

    3.5. Temperature sensor The temperature sensor is an optional extra to measure the battery temperature. If used, the Lynx Shunt VE.Can will measure the temperature of the battery and can be used to drive the Lynx Shunt VE.Can alarm relay.

  • Page 10: Communication And Interfacing

    The GX device and the VRM will show all measured parameters, operational state, battery SoC and alarms. 4.2. NMEA 2000 Communication with a NMEA 2000 network can be established via the Lynx Shunt VE.Can VE.Can connection together with a VE.Can to NMEA2000 micro-C male cable.

    5.1.2. Orientation of Lynx modules If the Lynx System contains a Lynx Shunt VE.Can or Lynx Smart BMS, the batteries always have to be connected to the left side of the Lynx System and the rest of the DC system (loads and chargers) connect to the right side. This, so the battery state of charge can be correctly calculated.

Current rating Lynx modules The Lynx Distributor, Lynx Shunt VE.Can and the Lynx Power In are rated for a nominal current of 1000A, for 12, 24 or 48 System voltages. Page 9...

  • Page 13: Fusing

    5.2.3. Cabling The current rating of the wires or cables used to connect the Lynx Shunt VE.Can to batteries and/or the DC loads has to be rated for the maximum currents that can occur in the connected circuits. Use cabling with a sufficient core surface area to match the maximum current rating of the circuit.

  • Page 14: Installation

    • If the Lynx system contains a Lynx Smart BMS or Lynx Shunt VE.Can, the left side is the battery side and the right side is the DC system side.

    Lynx Shunt VE.Can 9. Battery monitor settings This chapter explains all battery monitor settings. In addition to this we also have a video available explaining these settings and how the interact with each other to achieve accurate battery monitoring for both lead-acid and lithium batteries.

  • Page 23: Charge Efficiency Factor

    Lynx Shunt VE.Can acid batteries can be calculated. For more information on the Peukert calculation, battery capacity and Peukert exponent see the Peukert exponent chapter. Default setting Range Step size 1.25 1.00 - 1.50 0.01 9.6. Charge efficiency factor The “Charge Efficiency Factor” compensates for the capacity (Ah) losses during charging. A setting of 100% means that there are no losses.

  • Page 24: Battery Capacity And Peukert Exponent

    Lynx Shunt VE.Can 10. Battery capacity and Peukert exponent Battery capacity is expressed in Amp hour (Ah) and indicates how much current a battery can supply over time. For example, if a 100Ah battery is being discharged with a constant current of 5A, the battery will be totally discharged in 20 hours.
