Abstract

Embodiments of this application provide a battery, an apparatus using a battery, and a manufacturing method and a manufacturing device of battery. The battery includes a battery cell and a thermal management component. The battery cell has a side wall and a bottom wall that are connected to each other. The thermal management component is configured to accommodate fluid to regulate temperature of the battery cell, where an accommodating portion is provided on the thermal management component, and configured to accommodate the battery cell, and the accommodating portion is attached to the bottom wall and side wall of the battery cell, to enable heat transfer between the battery cell and the thermal management component. The battery cell in the battery provided in the embodiments of this application can dissipate heat efficiently.

First claim

What is claimed is:

1. A battery, comprising:
a plurality of battery cells each with a side wall and a bottom wall that are connected, wherein the plurality of battery cells comprise at least a first battery cell and a second battery cell that are arranged adjacently; and
a thermal management component, configured to accommodate fluid to regulate a temperature of each of the plurality of battery cells, wherein an accommodating portion is provided on the thermal management component, and configured to accommodate the battery cell, wherein the accommodating portion is attached to the bottom wall and side wall of the first battery cell and the thermal management component is attached to the bottom wall of the second battery cell;
wherein a first flow channel and a second flow channel are provided on the thermal management component, the first flow channel and the second flow channel are separately configured to accommodate the fluid, the first flow channel and the second flow channel are isolated from each other, and the first flow channel and the second flow channel are provided opposite the first battery cell and the second battery cell, respectively.

2. The battery according to claim 1 , wherein temperature of the first battery cell is higher than temperature of the second battery cell before heat transfer.

3. The battery according to claim 1 , wherein the fluid comprises first fluid and second fluid, the first fluid circulates in the first flow channel, the second fluid circulates in the second flow channel, and a thermal conductivity coefficient of the first fluid is greater than a thermal conductivity coefficient of the second fluid.

4. The battery according to claim 1 , wherein the thermal management component further comprises a protruding portion, and the protruding portion is attached to the bottom wall of the second battery cell; and
the first flow channel is provided in the accommodating portion, and the second flow channel is provided in the protruding portion.

5. The battery according to claim 1 , wherein the battery further comprises a support member, wherein the support member is configured to support the battery cell, and the support member is connected to the thermal management component.

6. The battery according to claim 5 , wherein an accommodating groove is provided in the thermal management component, and the accommodating groove is configured to accommodate the support member.

7. An apparatus using a battery, comprising the battery according to claim 1 , wherein the battery supplies electrical energy to the apparatus.

8. A manufacturing method of batteries, used for manufacturing the battery according to claim 1 , comprising:
providing a battery cell, wherein the battery cell has a side wall and a bottom wall that are connected;
providing a thermal management component, and forming an accommodating portion on the thermal management component; and
assembling the battery cell and the thermal management component so that the accommodating portion is attached to the bottom wall and side wall of the battery cell, to implement heat transfer between the battery cell and the thermal management component.
