Can two EV chargers be combine to increase charging current?
Guess it would require one charger to be a master (comunicating with the car) and one or more slave chargers which need to be perfectly syncronized with the master. Thus the slaves need to messure the masters voltage and phase at the plug und control their own output to a very tight match, as already minimal differences in voltage and or phase will cause compensating currents between the chargers.
So from an engineering point, technical feasable? I think it is possible.
From a economical point (think such a solution adds quite some costs), customers which need to fiddle around with more adapters and cables, and reliability and security safety in 24/7 operation --&gt; I guess No is the right answer.
But it might be of interest for a operator or manufacturer of chargers to have modular power stages and combine several of them internaly to match different power classes.
