Method for switching between fast charging modes

A system for switching between fast charging modes, the system comprising:

• one or more processors;
• and
• one or more memory devices storing programming code comprising instructions which, when executed by the one or more processors, cause the one or more processors to:
• exchange information between a charger and a vehicle;
• perform, by a charge controller of the vehicle and based on the exchanged information, a first comparison between a high-voltage battery maximum voltage and a charger maximum output voltage;
• perform, by the charge controller, a second comparison between a high-voltage battery current voltage and the charger maximum output voltage when the high-voltage battery maximum voltage is greater than the charger maximum output voltage;
• enter the charge controller into a boost charging mode when the high-voltage battery current voltage is greater than the charger maximum output voltage;
• and
• enter the charge controller into a direct charging mode when the high-voltage battery current voltage is equal to or less than the charger maximum output voltage.

A non-transitory computer-readable medium comprising instructions which, when executed by one or more processors, cause the one or more processors to:

• exchange information between a charger and a vehicle comprising the one or more processors;
• perform, by a charge controller executing on the one or more processors of the vehicle and based on the exchanged information, a first comparison between a high-voltage battery maximum voltage and a charger maximum output voltage;
• perform, by the charge controller, a second comparison between a high-voltage battery current voltage and the charger maximum output voltage when the high-voltage battery maximum voltage is greater than the charger maximum output voltage;
• enter the charge controller into a boost charging mode when the high-voltage battery current voltage is greater than the charger maximum output voltage;
• and
• enter the charge controller into a direct charging mode when the high-voltage battery current voltage is equal to or less than the charger maximum output voltage.
