1. A battery management system comprising:
- a battery cell;
an analog front end coupled to a first ground;
a computer coupled to a second ground;
an insulating unit for insulating the analog front end from the computer; and
a first power switching unit for receiving a control signal from the computer through the insulating unit, controlling a distribution of power from the battery cell according to the control signal, and controlling a supply of the power to the insulating unit, wherein the first power switching unit comprises;
a transistor configured to be turned on or off according to the control signal;
a first resistor and a second resistor coupled to a first terminal of the transistor for distributing a voltage of the battery cell; and
wherein the battery management system further comprises a third resistor coupled between a second terminal of the transistor and an output terminal of the insulating unit through which the control signal is output.

Abstract
A battery management system (BMS), a method of controlling the same, and an energy storage system including the battery management system. The BMS may reduce costs by stably supplying power to an insulating unit in a power-saving mode even when an isolator has no built-in direct current (DC)-DC converter.
