I was going to say toy cars but really the helicopters cars and other items which use large batteries have gone over what one would call a toy.
Some of the drones used to take photos are quite large devices and clubs tend to run events where rapid charging is really required.
1000W for 5 minutes is not that much when compared with liquid fuel pouring in the two stoke mixture used with compression ignition engines is so much quicker than a recharge.
Looking at electric cars it would seem a lot of work is going into rapid recharge.
The problem is to get 24 volt DC at a reasonable cost one needs to use high frequency and so reduce the size of the transformer so one is looking at a ready built unit rather than a collection of parts in order to use the switch mode technology and high frequency transformers.
The PC power supply does seem the most likely unit.
Hi Eric,
You are correct regarding the need for the 1000W, when charging multiples of large LI-ON cells.
I'm also looking at PC power supplies, LED lighting power supplies and other machine power supplies. They can be quite expensive though, this is why I'm looking at this option.
