  1. Batteries and Charging
    I had a Brusa NLG511 come in for repair. Symptoms: Would not charge, power LED just blinked. A quick bench test showed it had a short on the +15V supply... I could not located which part was shorted, so I hooked up the external supply and set it to +15V... And slowly turned up the current...

    Finished Soldering 6 Power Controller boards last night. :) In my Solectria E10, I am planning on having 4 parallel groups of 20 Leaf modules in series (150V @ 65Ah per group), and thus I need a way to pre-charge, connect, and disconnect them to/from the main vehicle power bus. That is the...
  3. Batteries and Charging
    I had a Brusa NLG513 Charger come in for repair with the following error message: ShortCirc PwrSt: ERR So obviously it has a short circuit in the power stage. ;) So I took it apart and checked all the IGBTs and diodes in the power stage... All tested good... I then contacted Brusa to see...
  4. Batteries and Charging
    I recently acquired a Brusa NLG511 battery charger, which is the correct voltage range for my truck. I have had a Brusa NLG513 battery charger for a few years, but its output is to high for my truck. And I wanted to see if I could convert the NLG513 to a NLG511. So I was really hoping that...

    This post might be useful for those looking to upgrade lead acid based 144V systems... Here is the configuration I came up with, while reusing the Nissan Leaf interconnects, safety covers, and BMS wiring. This is one of four 150V 65Ah modules for my Solectria E10. Total battery weight will...
  6. Batteries and Charging
    It appears to be a double locking connector, metal clip on the pin and then a plastic locking retainer. But I have not figured out how to remove the pins with out breaking the connector... I am sure it is something simple. Otherwise I can just cut and solder the wires, but that would be a lot...

    Does anyone have the CAD drawing of the AEV6505A Contactor (Nissan Leaf). I looked around on Panasonic's website, but I could not find one that was close: https://www3.panasonic.biz/ac/e/control/relay/vehicle/ev_special/index.jsp Interestingly they are filled with hydrogen and use a permanent...
  8. Batteries and Charging
    I am working on a Version 2.0 of the Battery Pack Sniffer. Requested Features: Work with battery packs other than the Nissan Leaf. ;) Control the power contactors and pre-charge relay. User configurable cell voltage limits to enable / disable the battery pack. User configurable cell...

  15. Batteries and Charging
    Hello, I am not sure if anyone is interested in this, but I am in the process of building a 10kW Bi-directional buck-boost converter (48V - 500V). This will be used as a battery pack simulator (replacing my large stack of AGM batteries, which are retired from my truck)... I repair motor...

    Do you have some old non functional Solectria or Brusa parts sitting around the basement or garage? I will buy them, and/or repair them if needed. List of parts repaired: http://www.wolftronix.com/EV.htm Thanks, Wolf
  18. Batteries and Charging
    Hello, I have a 2013 Nissan Leaf battery pack, which I am using to reverse engineer the serial protocol between the microcontroller and the balancing ICs, so I can reconfigure the pack for use in my Solectria E10, and still use the BMS. I recently purchased a 2013 BMS on eBay and it was...
