Phillips Industries' Permalogic Smart-Charge trailer power management system is designed for liftgate and auxiliary battery banks.

The system recognizes and automatically manages the best power sources to charge the batteries from available sources at the same time.

The Permalogic Smart-Charge system can pull from the following sources individually or collectively, including the dual/single pole liftgate charging system, the tractor batteries, the reefer or from a fourth source like solar power.

The system has built-in low voltage detection to avoid draining power sources and an LED indicator to display which power input source is being used.
