Vehicle battery pre-charge feature
First Claim
1. A system for pre-charging a hybrid vehicle comprising:
- a battery having a state of charge;
a transmission;
an engine having an on mode, coupled to the transmission and configured to output torque when in the on mode;
a motor-generator having a drive mode and a regeneration mode, coupled to the battery and the transmission and configured to output torque to the transmission when in the drive mode and to convert torque from the transmission to electrical power for recharging the battery when in the regeneration mode;
a button configured to receive a user input to activate a pre-charge logic to increase the state of charge of the battery or a user input to deactivate the pre-charge logic; and
a hybrid controller coupled to the battery, the motor-generator, the button and the engine and configured to cause the state of charge of the battery to increase in response to the button receiving the user input to activate the pre-charge logic and the state of charge of the battery being less than or equal to an upper state of charge threshold by instructing the motor-generator to operate in the regeneration mode and instructing the engine to operate in the on mode until at least one of;
the button receives the user input to deactivate the pre-charge logic, orthe state of charge of the battery reaches or exceeds the upper state of charge threshold.

Abstract
A system and a method for a hybrid vehicle for pre-charging the battery. A hybrid vehicle includes a battery having a state of charge (SOC), an engine configured to charge the battery, an actuation device having an on state and an off state, and a processor configured to activate the engine to charge the battery when the actuation device is switched to the on state until the SOC reaches a required SOC. The required SOC may be input by a driver and may exceed a normal maximum SOC utilized by the hybrid vehicle. The pre-charge feature can override the normal hybrid vehicle battery management logic. The required SOC allows the driver to perform reverse maneuvers without running out of battery power.

8. A hybrid vehicle comprising:
-
a battery having a state of charge; a transmission; a sensor configured to detect data usable to determine a current location of the vehicle; a memory configured to store a stored location; an engine having an on mode, coupled to the transmission and configured to output torque when in the on mode; a motor-generator having a drive mode and a regeneration mode, coupled to the battery and the transmission and configured to output torque to the transmission when in the drive mode and to convert torque from the transmission to electrical power for recharging the battery when in the regeneration mode; and a processor coupled to the battery, the sensor, the memory, the engine and the motor-generator and configured to; compare the current location of the vehicle to the stored location, and activate a pre-charge logic in response to the current location of the vehicle being within a predetermined distance of the stored location, the pre-charge logic causing the state of charge of the battery to increase by instructing the motor-generator to operate in the regeneration mode and instructing the engine to operate in the on mode until at least one of; a user input to deactivate the pre-charge logic is received, or the state of charge of the battery reaches or exceeds an upper state of charge threshold. - View Dependent Claims (9, 10, 11, 12, 13)

14. A method for pre-charging a hybrid vehicle comprising:
-
receiving, at a hybrid controller coupled to an engine, a motor-generator and a battery, a first signal from a button indicating that the button has been switched from an off state, indicating that a pre-charge logic is not activated, to an on state, indicating that the pre-charge logic is activated, wherein the first signal is to increase the state of charge of the battery; activating, by the hybrid controller, the pre-charge logic in response to receiving the first signal, the pre-charge logic causing the engine to output torque to a transmission and the motor-generator to convert torque from the transmission to electrical power for recharging the battery; and deactivating, by the hybrid controller, the pre-charge logic in response to at least one of; receiving a second signal from the button indicating that the button has been switched from the on state, indicating that the pre-charge logic is activated, to the off state, indicating that the pre-charge logic is not activated, or determining a current state of charge of the battery reaches or exceeds an upper state of charge threshold. - View Dependent Claims (15, 16, 17, 18, 19)
