Abstract: A method for heating a power battery (1), an apparatus for heating a power battery (1), an electronic device, a system for heating a power battery (1), and a storage medium. The heating method includes: acquiring a current state parameter value of the power battery (1); and heating the power battery (1) using a corresponding heating mode based on the current state parameter value. After the temperature of the power battery (1) rises, the discharge capacity of the power battery (1) increases, and charging can be achieved.

Abstract: A method includes: acquiring actual temperature rise data of the power battery in a self-heating process of the power battery; acquiring preset calibrated temperature rise data corresponding to a self-heating current of the power battery; and controlling the self-heating of the power battery based on the actual temperature rise data and the preset calibrated temperature rise data. Since the self-heating of the power battery is controlled based on the actual temperature rise data and the preset calibrated temperature rise data in the present application, when there is a large difference between the actual temperature rise data and the preset calibrated temperature rise data, it can be determined that the temperature rise of the power battery is abnormal. In this case, a corresponding strategy can be adopted to ensure normal operation of the self-heating of the power battery.

Abstract: An adjustable offset umbrella has a generally vertical main pole and a sliding member slidably mounted to the main pole. The sliding member includes a locking mechanism for securing it at a desired location along the main pole. One end of an arm is associated with the sliding member, and the other end supports an umbrella canopy. A winding mechanism is associated with the sliding member and moves with it. A line extends from the winding mechanism to the umbrella canopy. Operating the winding mechanism opens and closes the umbrella canopy, and moving the sliding member up or down the main pole adjusts the angle of the canopy with respect to the main pole.
