Disclosed herein is a switch system for rechargeable power storage devices (PSDs). The switch system includes a controller and a first and second switching modules. The first switching module is serially-connected to a PSD. The second switching module is connected in parallel to the PSD and the first switching module. Each switching module is switchable by the controller between: a state S1, wherein current cannot flow (through the switching module) in a first direction; a state S2, wherein current flow cannot flow opposite to the first direction; a state S3, wherein current may flow in both directions; and a state S0, wherein current cannot flow in any direction. The switch system is configured to preclude joint states (S1, S2), (S1, S3), (S3, S2), (S3, S3), with the first and second entries denoting states of the first and second switching modules, respectively, thereby preventing possibility of short-circuit.
