US7782021B2 24 3.0 2007-07-18 Battery charging based on cost and life
One embodiment of the present subject matter includes a system that includes a battery, an electric vehicle, the battery coupled to the electric vehicle to propel the electric vehicle, and a charging circuit to charge the battery. The embodiment includes a charging cost circuit to estimate a charging cost rate and to turn on the charging circuit. The embodiment also includes a timer circuit to provide a time signal to the charging cost circuit. The embodiment is configured such that the charging cost circuit is to turn on the charging circuit during a first time period in which the charging cost rate is below a first threshold until the battery reaches a first energy stored level, and to turn on the charging circuit during a second time period in which the charging cost rate is above the first threshold.

US20100138092A1 16 2.5 2009-11-05 Battery charging time optimization
system
A system for optimizing battery pack charging is provided. This is achieved by delaying the coupling of auxiliary systems (e.g., battery cooling systems) to the external power source during charging in order to optimize the battery pack charge rate limited only by the available power. Once surplus power is available, for example as the requirements of the charging system decrease, the auxiliary system or systems may be coupled to the external power source without degrading the performance of the charging system.
