After upgrading the main battery pack in MR02EV to 310 Volts of Nissan Leaf battery modules charging with my 5.5 Amp TC Charger was very slow. So I jumped at the chance to purchase a second hand 16A, 3.3kW, Brusa NLG513 charger.

Being second hand the Brusa was configured with an internal pre-caned charging profile for a 144 Volt lead acid battery pack. Which was very different to what I needed being; external CAN control from a BMS, charging a 370 Volt Lithium-ion battery pack.
Brusa NLG5 Documentation
Changing the Brusa configuration is relatively simple using the NLG software, however, there are some traps to be aware of:
I have a Degree in Electrical Engineering from the University of Technology Sydney and am employed in Broadcast Television Industry. My hobby is the (continuing) modification of MR02EV. I am also the National Treasurer of the Australian Electric Vehicle Association.
