Problems solved by technology

However, although the circuit board embedded in the resin is disclosed, there is no disclosure or hint about the connection method with the battery, etc.
Therefore, in the case of connecting the surface of the battery on the side of the safety valve with a connector, it is not clear how to maintain airtightness with the partition wall.
In addition, there is a problem that it is difficult to align the safety valve of the battery with the opening of the partition wall, and if the positioning is performed with a recess, a space will be created between the batteries and the size cannot be reduced.
In addition, since the battery and the circuit board are fixed with resin and built in, there is a problem in the miniaturization of the battery module.

Embodiment Construction

[0039] The battery module of the present invention includes: a plurality of batteries; a casing that accommodates a plurality of batteries; a cooling pipe that is arranged along the plurality of batteries in the casing and has a refrigerant inside; Molten material composition.

[0040] With such a configuration, the contact area with the batteries is increased by the cooling pipes provided along the plurality of batteries, and the cooling effect can be increased. Furthermore, when an abnormality occurs in the battery and heat is generated, the cooling pipe is melted and the refrigerant flowing out from the inside can quickly cool the battery by the latent heat effect. As a result, temperature rise due to charging and discharging can be suppressed during normal operation, and when the battery becomes abnormally high in temperature such as in case of battery fire, the battery can be quickly cooled to suppress thermal influence on other batteries.

[0041]Here, it is preferable ...

Abstract

Provided is a battery module equipped with a plurality of batteries, a case (50) in which the plurality of batteries are arranged and housed, and a cooling pipe (70) that is disposed within the case (50) along the plurality of batteries and that is provided with cooling medium in the interior. The cooling pipe (70) comprises materials that melt when the temperature of the batteries increases to a prescribed temperature or higher.

Description

technical field [0001] The present invention relates to a battery module in which a plurality of batteries are arranged and accommodated in a case, and a battery pack using the same. Background technique [0002] In recent years, from the viewpoint of saving resources and energy, there has been an increasing demand for secondary batteries such as nickel hydrogen, nickel cadmium, and lithium ion that can be used repeatedly. Among them, lithium ion secondary batteries are characterized by high electromotive force and high energy density although they are light in weight. Therefore, there is an increasing demand as a power source for driving various types of portable electronic devices such as mobile phones, digital cameras, video cameras, and notebook computers, or mobile communication devices. [0003] On the other hand, in order to reduce the use of fossil fuels and reduce CO 2 As a power source for driving motors such as automobiles, expectations for battery packs are inc...
