Abstract

The invention discloses an electric core heating temperature control method. The method includes: determining a preheating temperature range and a normal working temperature range of an electric core,wherein the preheating temperature range is lower than the normal working temperature range; judging whether the electric core is in a charge-discharge state, and measuring the electric core temperature; if the electric core is not in a charge-discharge state and the electric core temperature is lower than the preheating temperature range, heating the electric core to an upper limit of the preheating temperature range; if the electric core is in a charge-discharge state and the electric core temperature is lower than the normal working temperature range, heating the electric core to an upperlimit of the normal working temperature range. Compared with the prior art, the method provided by the invention divides the electric core heating process into two parts, i.e. a preheating part and afast heating part, so that the electric core can be rapidly heated to the normal working temperature range during charging and discharging, and the heating speed is fast, the energy consumption is low, and the efficiency is high.

Description

technical field [0001] The invention belongs to the field of lithium batteries, and more specifically, the invention relates to a method for heating and controlling the temperature of a battery cell. Background technique [0002] Non-renewable energy is increasingly scarce in today's society, and the environmental pollution caused by non-renewable energy is becoming more and more serious. Therefore, various new energy sources, especially technologies in the field of lithium batteries, are developing more and more rapidly. However, due to the limited operating temperature range of lithium batteries, the temperature control system has become an essential part to ensure the normal operation of lithium batteries. [0003] At present, when the lithium battery is charged and discharged in a low temperature environment, the temperature control of the battery cell is basically realized by heating the heating film. When the battery cell needs to be charged and discharged, it takes a...
