Battery isolator


Battery isolator

A battery isolator is a one-way electrical valve, allowing DC current to flow in one direction, but not flow in reverse. They are commonly used on vehicles where multiple batteries or battery banks are used, including recreational vehicles, boats, utility vehicles, airplanes, and large trucks. The primary purpose for their use is to insure that a failure of a single battery or battery bank, will not wipe out an entire battery network. These are also used in vehicles with large car stereos which require multiple batteries.

Several technologies have been used to achieve control of DC current in this manner: silicon rectifier packages, Schottky rectifier packages, MOSFET rectifier packages, and conventional mechanical relays.
