Plug-In Hybrid Conversion Alert

Less than a month ago a Plug-in Hybrid Electric Vehicle (PHEV) caught fire and was destroyed. No one was hurt. The vehicle was a Toyota Prius with an after-market conversion to make the Prius a PHEV. The maker of the conversion kit (Hybrids Plus, of Boulder, CO) and several other organizations are investigating.

Hybrids Plus said, "After the incident we notified all owners of Hybrids Plus conversions, described to them the sequence of events in the incident, advising them not to drive until further information was available, and to call Hybrids Plus if there was any sign of a problem with their vehicle.

Over the past week we have conducted two extensive forensic examinations of the vehicle and of the battery pack using a team of experts that included Hybrids Plus technical staff, our cell manufacturer, and experts in electric vehicles." Read the complete statement.

This report from CRN (Cooperative Research Network, A Service of the National Rural Electric Cooperative Association):

On June 7, 2008, the converted Prius plug-in hybrid electric vehicle (PHEV) owned by Central Electric Power Cooperative in Columbia, SC, was destroyed by an internal fire that occurred during a routine drive. Thankfully, there were no injuries. But the converted Prius was destroyed. The cause of the fire is not known.

Until further investigation, CRN has advised grounding all test vehicles in the PHEV demonstration and is undertaking a detailed investigation. CRN has employed Electric Transportation Engineering Corporation (ETEC) of Phoenix, AZ, to perform an initial investigation on the PHEV. This firm has come highly recommended due to its experience with failure analysis and electric cars. The firm will work to determine the cause of the fire and make recommendations if more specialized forensics experts are needed to complete the investigation. The six other vehicles in CRN’s PHEV demonstration program have experienced only minor technical issues to date.
