Embodiment Construction

[0041]The aforementioned and other technical contents, features and effects of the present invention will be clearly presented in the following detailed description of preferred embodiments with accompanying drawings.

[0042] FIG. 1 is a side view of a common battery cell 101 . Although the metal casing is connected as a part of the negative electrode 104, most of the metal casing is covered by the light and thin plastic film 103, so that the negative electrode 104 can only be approached and conducted from the bottom of the battery. FIG. 2 is a side view of a battery cell 201 according to the first preferred embodiment of the present invention. The battery core 201 includes two opposite ends and a surrounding sidewall extending between the two ends to form a long body. The outer surface surrounding the side wall is defined herein as a peripheral side of the elongated body. Taking a cylindrical battery core as an example, the peripheral side is composed of countless points e...

Abstract

The invention relates to a battery cell provided on its peripheral side surface, instead of on its bottom surface, with a welding zone for connection to a metal strip. The invention also relates to a method for linking multiple battery cells in parallel or in series into a battery module, with spot welding connections to the positive and negative terminals not on opposite ends to improve production flow. Over current protection device is incorporated to form a compact battery module with internal over current protection.

Description

【Technical field】 [0001] The invention relates to a battery core, a battery assembly provided with the battery core and a battery assembly manufacturing method. The present invention also relates to a rechargeable battery system suitable for an energy-saving hybrid vehicle, a power storage system or a notebook computer, especially a battery system for interconnection of battery cells. 【Background technique】 [0002] At present, the science and technology industry has gradually tried to reduce the use of polluting energy sources such as burning oil and natural gas, which have limited storage and cause a large amount of carbon emissions. Electric energy as clean energy. Electric vehicles have thus become a hot topic at present. However, vehicles such as electric vehicles, on the one hand, are limited by the need to consume a large amount of electric energy to drive the motor, and must use a large number of batteries; on the other hand, the vehicle must cope with harsh enviro...
