Abstract
Provided a wakeup circuit of a battery sampling integrated chip in battery energy storage system. The wakeup circuit includes a power end at a power low-voltage side, an optocoupler, and a switch transistor; wherein a first end of a primary side of the optocoupler is connected with the power end at the low-voltage side, and a second end of the primary side of the optocoupler is connected with a grounding end at the low-voltage side, a secondary side of the optocoupler is connected with a chip-wakeup end at a power high-voltage side, and the chip-wakeup end is connected with a wakeup pin of the battery sampling integrated chip; the switch transistor is connected in series with the primary side of the optocoupler, a control end of the switch transistor is connected with a wakeup signal input end at the low-voltage side.
