Charging System

Greg McCrea of EV Conversions in Sacramento supplied me with the Zivan NG5 charger. Greg has worked diligently with the folks at Zivan to modify one of their existing designs of a 5kW charger that required a 3-phase AC supply to run on single phase. After working out a couple of manufacturing defects (none related to the single phase conversion) it's been working fine with about 30 charge cycles under its belt to date. It's quite large as shown in the picture above on the left so it might be difficult finding a place for it in smaller vehicles. Also, it can get a bit toasty given that it puts out only 4kW for 5kW input. I hooked up the power cord to an L6-30 twist-lock connector mounted in the front bumper behind the license plate that hinges up for access to the plug.

The Zivan Smoother battery manager resides inside the cab because I didn't think it could withstand the harsh environment under the hood both from an EMI and weather standpoint. I sacrificed one of the small jump seats just behind the passenger door as shown in the center picture. It was just enough space for the smoother and conceals it nicely when folded up (top center) and keeps the high voltage connection out of harms way. When down, the display is easily viewed by the driver by looking behind the passenger seat and the control buttons are within arms reach. Note the HP200LX on top sucking data from the smoother's brain.

The third picture is of the box that houses the current sensor that comes with the smoother. It's mounted under the cab. So, to keep the elements away, I put it in an aluminum box. A 1/2" copper rod passes through the box and hall effect current sensor with the traction pack cables attaching to each end. It's shown here of course with the cover of the box removed.
