Abstract

Disclosed herein is a switch assembly electrically couplable to a rechargeable power storage device (PSD). The switch assembly includes an electrical input A, an electrical output B, and first and second conduction paths there between, passing through, and circumventing, the PSD, respectively. A positive polarity of the PSD points from A to B. The switch assembly is switchable between: (i) a state, wherein current is capable of flowing from A to B simultaneously through the first and second conduction paths but is incapable of flowing from B to A the second conduction path, (ii) a state, wherein current is capable of flowing between A and B through the second conduction path but current flow through the first conduction path is blocked, and (iii) a state, wherein current is capable of flowing between A and B through the first conduction path but current flow through the second conduction path is blocked.

Dependent claims

A switch system for one or more rechargeable power storage devices (PSDs), the switch system comprising a controller and a switch assembly, functionally associated with the controller;

wherein the switch system further comprises an electrical input (EI), an electrical output (EO), a first conduction path (FCP), and at least one additional conduction path (ACP) between the EI and the EO, such that the FCP passes via the PSD, with a positive polarity of the PSD pointing from the EI to the EO, and each of the at least one ACP circumventing the PSD;
and
wherein the switch assembly is switchable by the controller at least between:
a first assembly state Q1, wherein current is capable of flowing from the EI to the EO simultaneously via the FCP and one or more of the at least one ACP but is incapable of flowing from the EO to the EI via any of the at least one ACP;
a second assembly state Q2, wherein current is capable of flowing between the EI and the EO via one or more of the at least one ACP but current flow via the FCP is blocked;
and
(i) a third assembly state Q3, wherein current is capable of flowing between the EI and the EO via the FCP but current flow via each of the at least one ACP is blocked, or (ii) an alternative third assembly state Q3′, wherein current is capable of flowing from the EI to the EO via one or more of the at least one ACP but is incapable of flowing from the EO to the EI via any one thereof, and current flow via the FCP is blocked.
