Electrical energy storage device and electricity conducting mechanism thereof

An electricity conducting mechanism of an electrical energy storage device having a casing with an input terminal set and an output terminal set respectively at two opposite sides of the casing, being provided inside with a protection circuit board to perform function of controlling voltages thereof, and being provided inside with at least one electrical energy storage unit electrically connected to the protection circuit board, the electricity conducting mechanism comprising:

• a first clamping terminal disposed in the input terminal set;
• a second clamping terminal disposed in the output terminal set, structures of the first clamping terminal and the second clamping terminal being shaped to fitly engage with each other;
• and
• a conductive component having two opposite ends extended into the input terminal set and the output terminal set and therefore respectively connected to the first clamping terminal and the second clamping terminal, and the conductive component being connected to the electrical energy storage unit via the protection circuit board;
• wherein when two of electrical energy storage devices are connected, the first clamping terminal of one of the electrical energy storage devices is engaged with the second clamping terminal of the other of the electrical energy storage devices, and the electricity conducting mechanism performs function of dynamic voltage auto-balancing based on physical flow of voltages until voltages of all the electrical energy storage devices reach a constant value, and voltage differences between the electricity conducting mechanism and the electrical energy storage unit and current volumes are detected and controlled by the protection circuit board.
