Problems solved by technology

During the heating process, the battery temperature change is monitored, the heating module is started when the battery temperature is low, and the heating module is turned off when the battery temperature is high, but the speed of the battery temperature change is not considered. If the battery internal temperature changes suddenly, there will be safety hazards. Hidden danger

Abstract

The invention relates to a safe heating method for batteries in a battery replacement cabinet bin and a battery replacement cabinet. In the safe heating method for the battery in the battery changing cabinet bin, the following steps are executed in the heating process of a heating module of the battery changing cabinet: S1, acquiring and judging whether the temperature rising speed of a battery cell is greater than a preset temperature rising speed of the battery cell; s21, if the temperature rising speed of the battery cell is greater than the preset temperature rising speed of the battery cell, heating of the heating module is suspended; and S22, if the temperature rising speed of the battery cell is not greater than the preset temperature rising speed of the battery cell, the heating module continues to heat. The heating module is closed when the temperature of the battery cell rises too fast, potential safety hazards are eliminated, and the safety of the battery replacement cabinet is improved.

Description

technical field [0001] The invention relates to the field of power exchange cabinets, and more specifically, to a method for safely heating batteries in a compartment of the power exchange cabinet and the power exchange cabinet. Background technique [0002] The charging performance of the rechargeable battery is obviously reduced at low temperature, which seriously restricts the charging of the rechargeable battery at low temperature. For example, under low temperature conditions, the effective discharge capacity and effective discharge energy of lithium-ion batteries will decrease significantly, and at the same time, it is almost unchargeable in an environment below -10°C, which seriously restricts the application of lithium-ion batteries. . To solve the problem of charging the rechargeable battery in a low temperature environment, in the prior art, a heating module is installed in the power exchange cabinet to heat the battery. During the heating process, the battery te...
