Abstract

A power control system may include at least one of batteries, a motor, and a data logic analyzer that can interpret certain variable conditions of a transport, such as a tractor trailer, moving along a road or highway. The data can be used to determine when to apply supplemental power to the wheels of a trailer to reduce fuel usage. One example device may include at least one of: a power creation module that generates electrical power, a battery which store the electrical power, a motor affixed to a trailer axle of a trailer which provides a turning force to the trailer axle when enabled to operate from the stored electrical power of the battery, and a motor controller configured to initiate the motor to operate according to a predefined sensor condition.
