29 May BK Precision donates a programmable load to Stanford Solar Car
It’s a 8502, 500v/300w programmable load complete with PC interface. So far I’ve been using it to do benchtop testing of the MPPT and discharge curves for the battery pack. So far the most exciting use by far has been to test the solar panels on the car. It helped us to identify a tracker on the car that was doing absolutely nothing.
That’s me, under the car with the load and my laptop testing panels.
That’s what I was staring at – an IV trace from the BK load, generated with a homebrew program using their serial interface. If anybody wants the source code, just shoot us an email and we’ll send it right over. It’s not the most robust software, but it gets the job done.
All things considered, this has worked out brilliantly well and we couldn’t be happier. Thanks BK Precision!
