Brusa NLG513 Charger

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.

Changing the Brusa configuration is relatively simple using the NLG software, however, there are some traps to be aware of:

• Firstly, it is very important to have a solid ground on pin 1 of the communications connector; otherwise communications with the external PC is very un-reliable.
• Secondly if you intend to control the Brusa via CAN communications, it is important to check the CAN command IDs. There are defaults, but my unit had been re-configured which caused loads of confusion.
