摘要（英）：

The invention discloses a CAN bus interface for a vehicle-mounted mobile charging device in the field of electric vehicles. The CAN bus interface for the vehicle-mounted mobile charging device comprises a CAN bus interface chip U3, a CAN bus transceiver chip U4, a first isolation chip U5 and a second isolation chip U6, wherein a TXD1 interface and a RXD1 interface are formed in the CAN bus interface chip U3; a TXD2 interface and a RXD2 interface are formed in the CAN bus transceiver chip U4; the first isolation chip U5 is positioned between the TXD1 interface of the CAN bus interface chip U3 and the TXD2 interface of the CAN bus transceiver chip U4; and the first isolation chip U5 is positioned between the RXD1 interface of the CAN bus interface chip U3 and the RXD2 interface of the CAN bus transceiver chip U4. The CAN bus interface for the vehicle-mounted mobile charging device has the advantages that the influence and interference of potential difference on the monitoring of the vehicle-mounted mobile charging device can be reduced and the CAN bus interface is also convenient for extension of the vehicle-mounted mobile charging device.
