Solution for Complex Electrical Circuit

Whilst it would be possible to set up a system of battery monitors, charging, fused circuits, voltage measurements and device/appliance control using discrete devices, it would be much easier, particularly for the end user if all those functions were controlled by the one device. 

Hence the development of the J35 and BatteryPlus35 Integrated Battery Management Systems (IBMS).

A critical feature of the J35 and BatteryPlus35 is that the batteries, generating devices and all 12V/24V loads are connected in together but separately controlled and monitored.

It also has the benefit of

  • All voltages and current flows can easily be measured and checked against each other.  In order to maximise the efficient charging of all system batteries, BMPRO has done extensive testing of all battery types, including the newer Lithium and Lead Crystal designs. That way all battery characteristics can be loaded into the IBMS software and optimum charging conditions can be maintained at all times.  An obvious benefit of this is that battery life is prolonged like for instance batteries are not being discharged to unacceptable levels. When multiple charging inputs are available, for instance both a mains charger and solar panels, then these can be regulated for not only the correct rate of charge but also to avoid voltage spikes and overcurrent conditions.

  • All the load circuits are wired in separately and can be shut off individually if there is a circuit fault. Unlike a fuse which will just blow, the circuit is monitored such that if the fault clears, ie blown globe or a temporary overload is removed, then the circuit will automatically reconnect, that is there is no need to replace a fuse or turn a circuit breaker back on. If the fault persists though, the circuit will remain disconnected.

  • In the event of batteries becoming discharged excessively, the IBMS can be programmed for a controlled shut down. Non-essential circuits like say a water pump and electric awning will be switched off first in favour of keeping the fridge or medical devices like a sleep apnea machine running. 
  • Part of the J35 package includes a tablet that can be used to control, monitor and operate everything, including items like turning lights on and off and operating the hot water system. A Bluetooth link is used to connect the tablet with the J35 which means that WiFi capability is not required. The good news is that whilst theIBMSsystem has been setup to be monitored in a fairly simple fashion, tech heads can set everything up to suit their own desires and interest. 

What the J35 and BatteryPlus35 offer is a comprehensive package that not only operates an entire 12V/24V Recreational Vehicle system at its peak efficiency but does so in a way that offers the most economic use of the overall system, including the all important batteries.

    1. Good afternoon Bob,
      The J35D is a direct replacement for the J35C.
      it is only the internals that makes the units different

      If you have any further questions, please feel free to contact our customer service on 03 9763 0962.

  1. Hello, when I press the pairing button on my node101 for 10+ seconds it doesn’t change to orange nor can I pair to my phone.
    Brought a new jayco in sept 19 with J35 b with solar.
    Have never been able to pair!
    Getting frustrated
    Thanks in advance
    Michael

    1. Hi Michael,

      ControlNode101 is not compatible with the smartphones; you would need to upgrade to ControlNode102 to be able to use a phone app. Do you have a JHub tablet in your van?

    1. Hi Matt,

      Unfortunately to use your own device with a JHub app, you need to use ControlNode102 or later. It’s not possible to use ControlNode101 with your iPad.

    I have a j35 C with 101 node ive change the battery from 100 ah to 170 ah andive change in app settings to the ah to suit above, but power hours remaining stays at 99.59ah I would think it should b 169.59 , on fully charged have i miss something , thanks

    1. Steve / Customer Service

      Good morning Christopher.
      The Early JHub tablet only has the capability in the the App to display 99.59HRS.
      Even when the battery capacity is 300amp/h it will display the same.

      The 99.59hrs is based on the amperage being drawn from the battery at the time, when you see this almost nothing is on. Once you turn on appliances in the caravan, the hours will adjust to the current power demands showing a reduction in the available hours.
      Regards

  3. I have a Silverline outback with a JHub and 101 node which has a continual green flashing light. Is this normal?

    1. Stewart / customer service

      Hi Reiner,

      The J35 will flash green once the battery is charged, it will also flash a sequence depending on the charge input (solar- 2 flashes, DC – 3 flashes). A single flash will appear if there is no battery connected.

      Regards,
      Stew
