The connection system is designed to facilitate electrical and data connections between the battery and the electric vehicle. The connectors are designed with alignment mechanisms to account for initial misalignment of the battery and vehicle while still ensuring positive contact between them. The alignment mechanisms also introduce compliance into the system to ensure that the mechanical components of the system are not placed under unwanted loads or stresses. The connection system houses data connectors carrying communication signals as well as power connectors carrying high voltage electricity. The data connectors are shielded to prevent interference caused by proximity to the high voltage elements. The connection system uses no mechanical latching or locking mechanisms.
