The multi-battery adapter (10) enables the electric bicycle to be extended with additional traction batteries (50) in a simple manner and without adapting the traction battery (40) or the drive unit (60).)

1. A multi-battery adapter (10) for establishing an electrical connection between at least two traction batteries (40, 50) and a drive unit (60) of an electric bicycle has

A drive unit connector (26) and at least two battery connectors (22, 24), wherein the drive unit connector (26) is electrically connected to the drive unit (60) and the at least two battery connectors (22, 24) are each electrically connected to a traction battery (40, 50), wherein a first battery connector (22) is electrically connected to a first traction battery (40) and a second battery connector (24) is electrically connected to a second traction battery (50),

a control unit (12) having a separate battery management module (18), an

A power supply switch (12), wherein the power supply switch (12) can be actuated by the battery management module (18) such that a power supply connection (66) can be established between the drive unit (60) and the first traction battery (40) and/or the second traction battery (50).

2. The multi-cell adapter (10) of claim 1, wherein the battery management module (18) is connected to the first traction battery (40) and the second traction battery (50) by battery signal lines (46, 56), respectively, and the battery management module (18) is connected to the drive unit (60) by a single drive unit signal line (68).

3. The multi-cell adapter (10) of claim 1 or 2, wherein the battery management module (18) has a total charge summer (16).

4. The multi-cell adapter (10) according to any one of the preceding claims, characterized in that the drive unit plug (26) and the cell plug (22, 24) are designed mechanically complementarily to one another.
