DC-DC Converter and Battery Equalizer Recall – North America

Dear Customer:

For more than a decade, Sure Power Inc. has sold battery equalizers and DC-DC converters through both vehicle manufacturers and through aftermarket distribution channels for installation on vehicles with 24V/12V dual voltage electrical systems, including buses, over the road trucks, and other specialty vehicle applications.

Sure Power, Inc. has decided that a defect which relates to motor vehicle safety exists in battery equalizers and DC-DC converters that have been sold for installation on vehicles with 24V/12V dual voltage electrical systems. The affected products were manufactured between January, 2000 and August, 2013. Sure Power, Inc. has reported this issue to the National Highway Traffic Safety Administration and will be undertaking a safety recall to replace the units in accordance with NHTSA’s regulations. NHTSA has assigned campaign number 13E050 to this recall campaign.

The specific potting compound used in the subject products for insulation was found to be capable of conducting electricity once exposed to significant thermal energy. Once electrically conductive, the material is capable of self-heating and maintaining temperatures capable of accelerating a thermal incident. Thermal energy can be sourced by various electrical failures, and Sure Power is still investigating whether there are application-specific contributions to the risk of failure. Electrical failures have been traced to water intrusion or solder joint fatigue resulting from ongoing expansion and contraction due to thermal cycling.

Confirmed incidents to date have demonstrated smoking or flame at the affected part with additional damage limited to adjacent/connected parts such as wire harnesses and cables. No injuries have been recorded to date. The failure mechanism is not detectable and no warning is given prior to thermal failure.
