摘要

A system for measuring a current from a battery with a Hall Effect sensor, the current powering a primary load and a secondary load. The system to calculate a status of the battery based on the measured current, then compare the status of the battery to a predetermined value. The system to activate a relay when the status of the battery is below a predetermined value, activation of the relay to prevent the current from powering the secondary load.

說明書

The transducer 125 may be configured to sense an electric field generated by the electric current 175 (FIG. 1) flowing from the battery 170 (FIG. 1) through the input terminal 130 and may generate data in response. By sensing the electric field created by a flow of electrons, the current can be measured and can be used to reduce losses associated with the measurement as compared to other measurement techniques such as calculating the current based on the voltage drop across a resistor. In one non-limiting exemplary embodiment, the transducer 125 includes a Hall Effect sensor. Positioning of the transducer 125 will be described in more detail with reference to FIG. 7 below.
