Battery holder

The present invention relates to a holder, and more particularly to a battery holder for holding a plurality of battery cans.

Since rechargeable lithium batteries (also known as secondary batteries) have high operating voltage (3.4~3.8 Volt), large energy density (>185 Wh/Kg), light weight, long life and environmental protection, they have been widely used. 3C electronic products, such as: Mobile Phone, Notebook (NB/PC), Tablet PC, Camcorder, and Digital Camera. According to IIT's 2009 statistics, the global sales of lithium battery cells reached about 3.05 billion. According to statistics, about 44% of the global lithium battery cells sold in the market are used in mobile phones and handheld devices, and about 31.4% are used in notebooks. Computers, and about 5.5% are used in other consumer electronics products, which use about 80% of the market for lithium batteries. In recent years, in response to factors such as the global climate anomaly caused by the greenhouse effect and the reduction of dependence on oil, all major countries and automobile manufacturers around the world have actively developed low-pollution and low (/zero) fuel consumption hybrid vehicles. (or hybrid vehicles), as the market for hybrid electric vehicles has matured, the demand for the lithium battery industry outside the above-mentioned product areas has also increased.

Generally, 3C products have a low operating voltage, and in order to reduce weight and volume, it is usually only necessary to use a single battery or a plurality of battery cells (Battery 40) connected in series or in parallel to provide sufficient power. Relatively speaking, electric vehicles need A large working voltage and sufficient capacity are required to supply sufficient power for the vehicle to travel; a lithium battery power source for an electric vehicle is a lithium battery module composed of a plurality of lithium batteries connected in series or in parallel with each other ( Battery Pack), an average of one electric car requires thousands of lithium batteries. Therefore, how to achieve rapid assembly and reliable fixation of a large number of lithium batteries at the same time is yet to be solved by practitioners.

In view of the above, the present invention provides a battery holder for fixing a plurality of battery cans, including a plurality of first plates, which are horizontally connected to each other in a first direction (for example, an x-axis direction), and each of the first plates includes a first One side, a second side, a plurality of first recesses, a plurality of second recesses and a plurality of first openings.
