Not sure if that's true. I think it's mainly to reduce the polution in central London. Otherwise, electric/hybrid cars wouldn't be exempt but charged the same amount!

That's an anomaly I'd say. The congestion charge was introduced in 2003, at that point electric cars were a curiosity, a fraction of a fraction of the market. I'd expect within 10-15 years the exemption will be removed.
The purpose was partly to reduce pollution, but as a secondary effect of the primary aim to reduce traffic:

I lived in London when it was launched, it was also to do with making the city centre flow again, so that those who actually needed to be there could travel in a reasonable amount of time.
Edit: Hmm. London's own stuff claims that it was originally largely intended to reduce use of personal vehicles, and then in 2008 the Mayor implemented the current system of charging based on pollution. Again, I suspect it'll go back to charging for electric vehicles once people actually own electric vehicles.
For example, bus lanes were made for busses, despite cyclists and motorcycles (on most red routes) being able to enter them.
