OSU Solar Trailer charging a TeslaSnapshot of Outback Inverters and other system componentsThis utility trailer was initially designed by OSU students as a senior project in mechanical engineering. It was constructed in 2007 to educate about photovoltaic (solar electric) energy and provide a renewable, portable power supply. It has been used to provide electricity to campus and community events at remote locations where power was otherwise unavailable. 

A few years later, some of the lead acid batteries failed and were removed, reducing the pack to three sub-packs of four 12V batteries. Still configured in a 48V system. This reduced pack weighed 1926lbs and was rated to produce 771Ah at 48V (37kW/hr), if it was new that is. It was rated to provide 250 cycles if discharged to 75% on each cycle. The heavy and aged battery pack performance was estimated at 29.5kW/hr at best. 

SHIFT EV was contracted to replace the lead batteries with Lithium. This included some system and structural design work, assembly, cabling, wiring and integration of the BMS with the inverter/charging system. We installed 48 180Ah LiFePO4 cells (593 lbs), rated to produce 29.2kW/hr. If you caught the math error, it's no error. The 180 case sized cells selected are now rated for >190Ah by the manufacturer. Cycle life of the new cells is rated for 2000 cycles (@ 80% DOD).

Lithium powered bugE trike, street legal

Customized BugE kit that we built for a customer who requested improved range, acceleration and top speeds. It is street legal and capable of highway speeds.
 
We modified the battery box to accept a 5kW LiFePo4 battery pack, installed a 400A adjustable DC controller and a reversible series-wound motor so the driver has the convenience of "powered" reverse.
