EFFICIENT BATTERY MANAGEMENT SYSTEM
First Claim
1. A battery management system (BMS) comprising of at least two blocks of electrochemical cells, with the voltage of each block being monitored with a high impedance circuit in response to a command from a central processor, with each block being connected to one or more independent isolated power supplies through a set of switches in a way that(a) When the said set of switches is not activated, the said corresponding block is not connected to any of the isolated power supplies,(b) When the said set of switches is activated, the said corresponding block is connected to one of the isolated power supplies,(c) The sets of switches are controlled in such a way that there would be no activation that would connect any two blocks to the same isolated power supply.

Abstract
A battery management system that monitors and controls the charging and discharging of a battery pack in the most versatile way at the block level with little dissipative loss but fast balancing is disclosed. The system has capability of using blocks of cells using different chemistry in the same battery pack. Such versatility makes it very useful for usage with erratic grid conditions, solar, wind and other natural energy sources for charging the battery.
