The application relates to the field of
power electronics, in particular to a modular power supply capable of mixing different batteries, a
discharge management method and equipment. The power supply comprises a basic unit, which is provided with a
DC bus, a DC power distribution module connected to the
DC bus, a first type battery access interface connected to the
DC bus through the DC power distribution module, a second type battery
access port, a bidirectional DC / DC module arranged at the second type battery
access port and having an output end connected to the DC
bus, and a monitoring module in communication connection with the bidirectional DC / DC module. The first type battery access interface and the second type battery
access port are each provided with a functional slot, and each slot has a unique address code. The monitoring module is configured to identify the address codes of the slots and the types of the connected equipment, confirm the type combination of the accessed batteries, and select and execute a corresponding
discharge control strategy according to the type combination. The application can support the safe mixing of different types and
voltage grade batteries.
