Abstract
A method for purging air from a cooling system including operating one or more pumps at a selected speed for a first time interval, waiting a second time interval with the one or more pumps off or at a reduced speed relative to the selected speed, and repeating the steps of operating and waiting multiple times.
Claims13
A battery cooling system, comprising:
- one or more flexible bladders each configured to contact a set of batteries, wherein the flexible bladders comprise a serpentine fluid pathway;
- one or more pumps in fluid communication with the one or more flexible bladders;
- one or more processors;
- and
- one or more memory devices having stored thereon instructions that when executed by the one or more processors cause the one or more processors to:
- while the one or more pumps operate at a first constant speed, receive a first signal;
- in response to receiving the first signal, perform operations including:
- operate the one or more pumps at a second selected speed for a first time interval;
- wait a second time interval with the one or more pumps off or at a third reduced speed relative to the second selected speed;
- and
- repeat the steps of operating and waiting for a predetermined number of times;
- receive a second signal;
- and
- in response to receiving the second signal, perform operations including:
- operate the one or more pumps at the first constant speed.

- repeat the steps of alternatively operating at the second selected speed and the third reduced speed for a predetermined number of times, the predetermined number of times being at least five times;
- receive a second signal;
- and
- upon receiving the second signal, return the one or more pumps to normal operation by operating the one or more pumps at the first constant speed.
