Abstract

The invention discloses a single battery, a battery pack and a vehicle equipped with the battery pack. The single battery comprises a shell, electrodes and a cell, wherein the electrodes include a positive electrode and a negative electrode arranged on the shell; at least one of the positive electrode and the negative electrode comprises two polar columns; the polar columns are both applicable to electrical connection; the cell is arranged in the shell, and the cell comprises a positive electrode plate, a negative electrode plate and a diaphragm; the positive electrode plate is electrically connected with the positive electrode; and the negative electrode plate is electrically connected with the negative electrode. According to the single battery disclosed in the embodiments, at least one of the positive electrode and the negative electrode is provided with two polar columns; the polar columns are electrically connected with an external power supply to enable the positive electrode plate or the negative electrode plate to form a short circuit, so that automatic heating to the interior of the cell can be realized under a condition of slightly modifying the manufacturing process of the single battery.

Description

technical field [0001] The invention relates to the technical field of battery manufacturing, in particular to a battery cell, a battery pack and a vehicle with the same. Background technique [0002] The battery is a kind of chemical power source, which realizes charging and discharging through chemical reactions, because the chemical reaction rate is significantly affected by temperature. Generally, when the temperature decreases, the chemical reaction rate decreases, resulting in an increase in the internal resistance of the battery, a decrease in discharge power, and a decrease in discharge power. , By increasing the battery temperature, the internal resistance of the battery can be reduced, and the discharge capacity and charge capacity of the battery can be improved. [0003] In the related art, the method of heating the battery with a heating sheet has a slow heating speed and a long time, and the usage of the heating sheet is relatively large, and the electronic chan...
