After upgrading the main battery pack in MR02EV to 310 Volts of Nissan Leaf modules, charging became very slow using my 5.5 Amp TC Charger. So, I jumped at the chance to purchase a second hand Brusa NLG513 air cooled charger.
NLG513 Air Cooled Specifications

Maximum Input Power (by input current eff = 16 A) 3,80 W
Maximum Charging Power 3,300 W
Voltage Range 200 – 520 V
Charging Voltage Accuracy ± 1 %
Maximum Charging Current 12.5 A
Charging Current Accuracy ± 2 %
Maximum Charging Current - ripple 100 %, fr = 2 fn (100 / 120 Hz) 12.5 12.5 A
Efficiency (P = Pa1max) 93
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.

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.
