I imagine that the proposed swapping stations would be able to automatically detect a damaged battery. I'm not an expert, but monitoring the voltage curve during a test charge/discharge cycle would probably get you pretty close. Remove them from the system and, assuming a subscription program, charge the offending driver for the cost of the battery or refurbishment.
