BCH has been originally set as a token to prevent BIP148 splitting bitcoin with the hard fork.
Craig Wright, the man who claims to be the real Satoshi Nakamoto said that they created an SV chain to bring BCH closer to the original Bitcoin protocol. The BCH hard fork is scheduled for November 16th, 2018 at 00:40 AM (UTC+8) This will lead to two different protocols, Bitcoin Cash ABC(Adjustable Blocksize Cap) and Bitcoin Cash SV (Satoshi Vision).
