Abstract
A pulse charging profile for a vehicle battery is synchronized with driver or vehicle demanded current disturbances by phase tracking the fundamental frequency of the desired pulse charging profile to those driver or vehicle demanded current disturbances. When these driver or vehicle demanded disturbances are not active, the tracked charging profile is honored.
Claims17
A method for pulse charging a battery having a target pulse charge profile, the method comprising:
- determining an adapted phase of the target pulse charge profile based on recent battery usage including determining whether measured battery power is less than or greater than a predetermined threshold;
- and
- initiating pulse charging of the battery at the determined adapted phase.
A system for pulse charging a battery having a target pulse charge profile, the system comprising:
- at least one controller configured to determine an adapted phase of the target pulse charge profile based on recent battery usage including determining whether measured battery power is less than or greater than a predetermined threshold and to initiate pulse charging of the battery at the determined adapted phase.
