The invention provides an endurance system and method of an electric vehicle. The endurance system comprises a vehicle-mounted battery pack, a vehicle control unit, an endurance battery pack, an automatic bidirectional control switch and a power generation unit, the first BMS is used for detecting the first SOC of the vehicle-mounted battery pack and sending the first SOC to the vehicle control unit; the vehicle control unit is used for comparing the first SOC with a first set value, and if the first SOC is smaller than the first set value, first control instruction information is generated; according to the first control instruction information, an automatic bidirectional control switch is controlled to be switched to an endurance battery pack to supply power to the vehicle; the power generation unit charges the endurance battery pack and/or the vehicle-mounted battery pack; seamless switching between the vehicle-mounted battery pack and the endurance battery pack can be achieved through the automatic bidire
