Method for controlling lower limit of state of charge of power battery, and vehicle

A vehicle comprising:

• a device for controlling a lower limit of a state of charge of a power battery, the device comprises:
• q temperature sensor, configured for detecting a minimum ambient temperature for at least a period of time;
• a prediction unit, configured for predicting a minimum ambient temperature within a preset period of time after the at least a period of time according to the minimum ambient temperature within the at least a period of time;
• and
• a processor, configured for:
• determining, according to the minimum ambient temperature within the preset period of time, a minimum state of charge value that is able to meet power requirements for starting an engine of a vehicle under the minimum ambient temperature within the preset period of time;
• and
• adjusting the lower limit of the state of charge according to the minimum state of charge value.

A machine-readable storage medium storing with instructions, wherein the instructions are configured to execute a method for controlling a lower limit of a state of charge of a power battery, and further configured to execute:

• detecting, through a temperature sensor, a minimum ambient temperature for at least a period of time;
• predicting a minimum ambient temperature within a preset period of time after the at least a period of time according to the minimum ambient temperature within the at least a period of time;
• determining, according to the minimum ambient temperature within the preset period of time, a minimum state of charge value that is able to meet power requirements for starting an engine of a vehicle under the minimum ambient temperature within the preset period of time;
• and
• adjusting the lower limit of the state of charge according to the minimum state of charge value.
