1050MA then it drops to 350ma for the topping/balancing.
MIMA Honda Insight Modified Integrated Motor Assist - MIMA Pack Whack and rebalancing the battery
It is called the universal dual rate grid charger.
The prototype has a red lexan front panel, and it is part way down the page.
The possible configurations are discussed in the blog.
The cost will depend on how it is constructed, and how many 48V supplies will be required.
If I had 20-50 units to build I would have a sheet metal shop make up a nice custom aluminum chassis with the mounting holes punched so the construction will go faster and be less costly than manually fabricating the chassis. Price may fall in the $400-$600 range, but don't hold me to that until I get a bit further along.
The chassis could be capable of mounting up to 4-48V supplies, and depending on the car it would be used for, 1-4 of the supplies would be used. I will have a voltage/current display on the unit, and will have a switchover voltage setpoint adjustment so the auto switch from 1A to 350ma can be set for any battery configuration.
With the subpack/cell tester project on the top of my list,and only one person working on things, I can't say when it would be available, hopefully by spring.
I am starting my Saturday workshops again, with the hopes of getting some help with the many projects on the list.

If anyone thinks you will want to buy one, send me an e-mail

And I will start a waiting list so I can better determine what quantity would be required, and have a better idea of cost and construction techniques required. The unit would come with the required internal connector and battery fan adapter so the connection to the pack would be to drill a hole for the connector, plug in the fan adapter, and connect to the pack with a spade lug(precharge resistor), and a ring terminal (negative top terminal). The internal wiring would be fuse protected right at the connection points, as well as fusing and diode isolation on the supply internal wiring.
A lamp timer (not supplied) could be used on the AC input to allow a timed shutdown if desired.
Anyone in my area that would like to come over and help with the projects, just send me an e-mail by the Friday before.
