Answer Posted / pankaj verma
Main criteria for parallel connection is :
1. Both chargers should be connected in the same polarity.
2. Voltage of both the chargers should be same.
3. chargers should have identical specification.
Practically chargers are never used in parallel, they are
just momentarily paralleled in order to shift load of each
other so that maintenance work on each one can be carried out.
