Method and system for dynamically adjusting battery undervoltage protection

A system for dynamically adjusting battery undervoltage protection, comprising:

• an acquiring unit, configured to real time acquire a current operation environment temperature value of a battery;
• a selecting unit, configured to real time select a preset undervoltage protection voltage and a preset undervoltage protection delay time according to the temperature value acquired by the acquiring unit;
• a first determining unit, configured to real time determine whether an output voltage of the battery is less than the undervoltage protection voltage;
• a second determining unit, configured to determine whether a time interval when the output voltage of the battery is less than the undervoltage protection voltage satisfies the undervoltage protection delay time, when the first determining unit determines that the output voltage of the battery is less than the undervoltage protection voltage;
• and
• an enabling unit, configured to enable the battery undervoltage protection when the second determining unit determines the time interval when the output voltage of the battery is less than the undervoltage protection voltage satisfies the undervoltage protection delay time.
