Problems solved by technology

Although the phase change material used in the thermal management system of the battery module has the advantages of not requiring moving parts and no need to consume additional battery energy, but in the long-term phase change process, the phase change material also has a decrease in latent heat and is easily denatured. , the disadvantage of poor stability

Abstract

The invention discloses an energy storage module with automatic temperature control, comprising a box body (8), a controller (3), a battery cell (6), a temperature sensor (2), a metal heat conductionpipe (5), a flow control instrument (4) and a liquid nitrogen source (1). Placing the battery cell in the box body; The temperature sensor is arranged on the battery cell, and is used for detecting the temperature value of the battery cell. The temperature sensor is connected with the controller. The surface of the battery cell is provided with a metal heat conduction pipe; The metal heat conduction pipe is connected with a liquid nitrogen source through the flow rate controller; The flow rate controller is used to control the flow rate and flow rate of liquid nitrogen. The flow controller iscontrolled by a controller. The automatic temperature control energy storage module of the invention is easy to implement, has good refrigeration effect, and can effectively guarantee the safe and stable work of the battery cell.

Description

technical field [0001] The invention relates to an energy storage module with automatic temperature control. Background technique [0002] Facing the depletion of traditional energy and the deteriorating environment, the development of new energy industry must vigorously develop energy storage batteries with high safety, long life and high energy density. Electrochemical energy storage batteries mainly include sodium-sulfur batteries, vanadium batteries, lead-acid batteries, lithium-ion batteries, etc. Among them, lithium-ion batteries are the most common electrochemical energy storage batteries, which have been used in mobile phones, notebook computers and other fields. As we all know, the performance of the battery is closely related to the battery temperature. The temperature above 50°C will accelerate the aging of the battery, and the temperature above 120°C will cause the thermal runaway of the battery. [0003] The power type 48V / 100AH ​​battery module in the present ...
