1. Field of the Invention [0001] This invention relates to a smart charge and power supply device for mobile vehicles, and particularly to a smart charge and power supply device for mobile vehicles which provides increased efficiency by extending the run time of power supply.
2. Description of Related Art [0002] In face of the global worsening air pollution problem, governments all over the world have been actively encouraging industries to develop electric mobile vehicles (e.g.
electric boats, electric buses, or electric transporting vehicles) for replacing air-polluting vehicles with combustion engines, which are driven by petrochemical fuel, to achieve the purpose of saving energy and reducing carbon emissions. As electric mobile vehicles are powered by rechargeable batteries, charging facilities such as charging stations are of vital importance for providing battery recharge. Actually, at the moment batteries of electric mobile vehicles may be recharged only in charging stations.

As electric mobile vehicles are powered by rechargeable batteries, charging facilities such as charging stations are of vital importance for providing battery recharge. Actually, at the moment batteries of electric mobile vehicles may be recharged only in charging stations.
[0003] When a battery of a conventional electric mobile vehicles has run out of power, the battery protection circuit will cut off power supply straightaway, causing the moving electric mobile vehicles to come to an abrupt stop and get out of control due to instant power failure.
Therefore, when a battery is running out of power and the nearest battery swapping station is too far away, the driver may feel panic or an accident may be caused. Further, when an electric mobile vehicle may no longer move due to power failure, the driver will need to resort to a cart or a crane truck for help, which is a waste of time and money. Therefore, the technology of extending the run time of power supply is essential for the popularization of electric mobile vehicles. In view of this, after laborious research and experiments, the applicant has devised a smart charge and power supply device for mobile vehicles which provides increased efficiency by extending the run time of power supply.
