Lithium-Ion Battery Pack Voltage REgualtion?

How does one regulate the DC output of a lithium-ion battery pack? I’m looking for a regulated output of about 30VDC at 200A continuous, which can also support peak currents of about 1800A for about 30 seconds. Does a DC-DC converter that meets these requirements exist?

    There is not a big market for 54KW low voltage DC-DC converters. Maybe at 2KVolts. Needless to say, these power levels are DANGEROUS. If your business actually needs such a thing then you need to hire an engineer to make one for you and it will cost several thousand dollars and use hundreds of transistors.

    One would make a Stacked Power Supply of many supplies and regulate them separately.

    USING 8 PIECE LITHIUM BATTERIES IN SERIES CAN MAKE A 30V DC POWER SOURCE, OBTAIN THE 500AH RATE TYPE TO MAKE IT.

    IT CAN SUPPORT UNDER 10000A FOR LESS THAN 1 MINUTE IF THE FEEDER WIRE IS THICK ENOUGH.

    You would need a semi truck to haul such battery, that sort of power could light a neighborhood.

    Dispersed in substations a DC-DC regulator could work.

    Single stand alone source, you need something like a DC generator such used in welding or better.

    What are you trying to power? The only thing that would draw those kinds of current that i can think of would be an electric vehicle - and if that is the case, absolute voltage regulation is not important. Same goes for electrolysis/electroplating.

    If you are not incorporating the charge circuitry, the type of battery is not as important as the battery voltage range and current capability.

    I very much doubt there are any off-the-shelf solutions with that level of power rating in that voltage range.

    What battery voltage would it be working from?
