Abstract: A dual mode battery charging system and method of use are provided for use in an electric vehicle. The system utilizes at least two user selectable, charging operational modes. In a first operational mode, a state of charge circuit powers on the engine/generator system whenever the battery state of charge falls below a first level and until the battery state of charge reaches a second level, where the second level is higher than the first level. In a second operational mode, the state of charge circuit powers on the engine/generator system whenever the battery state of charge falls below a third level and until the battery state of charge reaches the second level, where the third level is lower than both the first and second levels.

Abstract: A dual mode battery charging system and method of use are provided for use in an electric vehicle. The system utilizes at least two user selectable, charging operational modes. In a first operational mode, a state of charge circuit cycles an engine/generator system on/off between a first level and a second level, where the second level is higher than the first level. In a second operational mode, the state of charge circuit cycles the engine/generator system on/off between a third level and a fourth level. After the fourth state of charge has been reached once, the state of charge circuit cycles the engine/generator system on/off between a fifth level and the fourth level, where the fifth level is higher than the third level and lower than the fourth level, and where the fourth level is lower than both the first and second levels.

Abstract: A method for limiting the adverse effects of temperature on the electrical energy storage system (ESS) of an electric vehicle after the vehicle has been turned off is provided. In general, whether or not coolant is circulated through a coolant loop coupled to the ESS depends on the difference between the ambient temperature and a preset temperature, the preset temperature typically corresponding to the temperature of the ESS.

Abstract: A system for optimizing battery pack charging is provided. In this system, during charging the coupling of auxiliary systems (e.g., battery cooling systems) to the external power source are delayed so that the battery pack charge rate may be optimized, 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.
