Specific embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings：
The utility model provides a kind of power cylindrical lithium battery module.The module mainly includes bus-bar, support, battery core group
Into by connector series connection between module.Support is provided with battery core hole, for fixing battery core；Bus-bar is passed through by copper bar and nickel strap
Laser spot welding is formed, and each battery core can be together in parallel, the effect that realization is confluxed.Connected by connector between module, reached
To assigned voltage value.
As shown in Figure 1-2, battery core putting hole 4 is provided with inside support 1, for installing cylindrical electrical core 2.The outer end panel of support 1
Limiting stand 7 is provided with, for aligning negative bus-bar positioning, while thickness of the height of limiting stand 7 more than copper bar 8 with nickel strap after compound
