Battery Chargers

04/09/2012 4:24 AM

I have battery charger for traction battery. But in the battery charger brochure they have given chargers of single phase, two phase, and three phase main supply.

I want to know the difference between two phase and three phase supply for the battery charger. And the two phase battery charger consumes more current compared to three phase.

" I want to know the difference between two phase and three phase supply for the battery charger"

the difference is that the three phase source has 50% more phases! I think it charges better with more phases.

Make sure to use a 2 or 3 phase battery to match the charger.

At the same U and P,

1-phase's P = square root 1*U*I

2-phases's P = square root 2 *U*I

3-phases's P = square root 3 *U*I

The higher the "multiplier" of the U, the lower I consumed for the same P maintained.
