Prior owner purchased this vehicle from a Government surplus auction. The EPIC was used on a military base and sold as surplus property in 2006. It sat in a warehouse until I purchased it on 02-24-2014. It was first titled in Arizona on the morning that I purchased it using the FA97 form provided by the government.

I have two of the Lockheed Martin 14.4 Kw "Blue Box" chargers for the vehicle both of which are fully functional.

02-28-2014: dropped the single 1200+ lb battery tray and began testing and reconditioning of the NiMh batteries. They are sitting at "0.44V to 0.01V" at this time.

04-04-2014: At 6:30 AM it came to life when the charger announced that it was beginning a complete charge

04-05-2014: There are a few more miles on the odometer as we check for "all systems go."

04-12-2014: Attempting to locate an early version of the DRB-III diagnostic tool and the PCMCIA card for it that has the software for the EPIC.

05-10-2014: 7032 miles
By comparison this thing is a Model S and the TEVan is a forklift.
Took it to the local Saturday "Cruise Night" and got a lot of attention from other Gearheads. (No-one had ever heard of it.)

05-12-2014: Range tested to 76 miles and still above 1/4 mark after three complete 0-full 5 hr charges and a dozen topping-up charges. Topping-up is necessary because the ONLY charger for this vehicle within 400 miles is at my house.

05-24-2014: 1/2 price day at Ecology auto parts. I bought the 3rd seat for the EPIC for less than $20. Now six of my Grandkids get to ride in the EPIC during the parades.
(Turned 7450 miles on the way home..)

05-26-2014: Found that after the charger announced, "The EV is 100% charged", the heat pump continued to run for more than an hour. In the morning I found that it was 18% more Kwhrs than what went into the pack.

My meter at the wall shows what was used for the charger, heat pump and coolant pump. The charger announces the Ahrs into the pack only.

10-08-2014: 8050 miles
