A battery energy storage module and a battery energy storage device. The battery energy storage module comprises: a structure body (), a support member (), and a cell group (). A cavity for accommodating the cell group () is formed inside the structure body (). The structure body () is provided with an opening. The cell group () is disposed in the cavity of the structure body () through the opening of the structure body (). The support member () is used for supporting the structure body () to protect the cell group () disposed in the cavity of the structure body (). Because the support member () is used for supporting the structure body () to protect the cell group () disposed in the cavity of the structure body (), the battery energy storage module can have strong impact resistance, and can be applied to a full vehicle environment alone without being disposed in a protection tray.

A bidirectional isolated communication circuit and method for a differential signal. The circuit comprises a first detection circuit used for receiving a first differential pair from a first direction, converting the first differential pair into a first level signal, and inhibiting common-mode interference; a second detection circuit used for receiving a second differential pair from a second direction, converting the second differential pair into a second level signal, and inhibiting common-mode interference; an isolation adjustment circuit used for being provided between the first detection circuit and the second detection circuit and performing communication isolation; and a watchdog circuit used for being awoken according to the first differential pair and/or the second differential pair, and enabling the bidirectional isolated communication circuit to enter from a small current working mode to a normal working mode to perform communication isolation.
