- the box body 41 may be made of aluminum.
- the wall thickness of the box can ensure the structural strength, and on the other hand, it can also play the role of temperature uniformity.
- the size of the charging base 1 can be greater than the size of a plurality of battery packs 4, and an electrical connection interface and a plurality of cooling structures matching the charging of a plurality of battery packs 4 can be arranged in series or in parallel on the charging base 1 to realize a charging base.
- the seat 1 can charge multiple battery packs 4 at the same time.
- the charging base 1 itself can be connected in series or in parallel, and the charging base 1 corresponds to the battery pack 4 one by one, for example, five charging bases 1 are connected in series in FIG. Space for charging station.
- the embodiment of the present application provides a charging device 10, the charging device 10 is suitable for charging the charging pack, the charging device 10 includes a charging base 1, the charging base 1 is set at a charging station, and the charging base 1 is provided with a 4. A charging interface for charging.
- the charging interface is suitable for electrical connection with the battery pack 4, so that when the battery pack 4 is placed on the charging base 1, the battery pack 4 can be charged through the charging interface.
- the charging base 1 in the charging device 10 in the embodiment of the present application may be the charging base 1 in the battery pack charging system of the aforementioned embodiment.
- first and second are used for descriptive purposes only, and cannot be interpreted as indicating or implying relative importance or implicitly specifying the quantity of indicated technical features. Thus, a feature defined as “first” and “second” may explicitly or implicitly include one or more of these features.
- “plurality” means two or more, unless otherwise specifically defined.
- a first feature being "on” or “under” a second feature may mean that the first and second features are in direct contact, or that the first and second features are indirect through an intermediary. touch.
- “above”, “above” and “above” the first feature on the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature.
- “Below”, “beneath” and “beneath” the first feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is less horizontally than the second feature.
