The invention discloses an electric vehicle power management module, an electric vehicle and a power management method. The electric vehicle power management module comprises a storage battery voltage detection module, wherein one end of the storage battery voltage detection module is in electric signal connection with a storage battery and a load, and the other end of the storage battery voltage detection module is in electric signal connection with a power control module; a control port of the DC/DC module is in electric signal connection with the power supply control module, and the power supply control module controls the working state of the DC/DC module through the control port; the power battery is connected with the input port of the DC/DC module, and the output of the DC/DC module is connected with the storage battery and the load; when the storage battery voltage detection module detects that the voltage of the storage battery is lower than a set value, the power supply control module starts the DC/DC module to convert the voltage output by the power battery into a storage battery charging voltage and/or a load power supply voltage. And under the condition that the power battery has enough electric quantity, the storage battery can be charged, so that the automobile can be started under the condition that the whole automobile is electrified.
