Description

Battery selection method for battery exchange and battery energy station thereof Technical Field The present invention relates to a battery selecting method for battery exchange and a battery power station thereof, and more particularly, to a battery selecting method for battery exchange and a battery power station thereof according to the number Of batteries, the State-Of-Charge (SOC) Of the battery and the current State Of Charge Of the battery in the battery power station. Background In recent years, with the rising environmental awareness and the advancement of electric vehicle technology, development of electric vehicles using electric energy as a power source instead of conventional vehicles using fossil fuel as power has become an important goal in the automotive field, and thus electric vehicles have become popular. In order to improve the voyage and the use willingness of electric vehicles, many countries or cities have already planned to set charging stations and battery energy stations in public places so as to provide charging or battery exchange for electric vehicles and/or electric motorcycles, so that the electric vehicles are more convenient to use. The peak and off-peak charging or battery requirements may be different for different electric vehicles. For example, the battery demand of an electric motorcycle during peak hours may be higher than during off-peak hours. During peak periods, the battery power station must charge the battery at a high rate in order to quickly bring the battery to a full state. However, during off-peak hours, the battery energy station can charge the battery slowly on the premise of saving cost, as the battery demand is not high, so as to meet the specific battery demand. Furthermore, the requirements of different electric vehicles for the number of batteries may also be different. On the other hand, users of electric motorcycles often use battery-exchanged power replenishment mechanisms during busy commute periods, as battery charging takes time to wait. Generally, one of the important costs for battery manufacturers is that rechargeable batteries have their life cycle limitations. Therefore, how to properly charge and exchange the batteries in the battery power station is also an urgent problem to be solved in the industry. Disclosure of Invention In view of this, the present invention provides a battery selection method for battery exchange and a battery power station thereof. The battery exchanging battery selecting method is suitable for a battery energy station for accommodating and charging a plurality of batteries. First, a battery exchange request is received. Then, a state of charge of each battery in the corresponding battery power station is obtained, and the batteries are ordered according to the state of charge of each battery so as to become a plurality of candidate batteries. A first selected operation is performed corresponding to the battery exchange request, wherein the first selected operation determines whether a plurality of first candidate batteries with next highest states of charge exist in the candidate batteries, wherein the states of charge of each corresponding first candidate battery are the same. When the first candidate battery exists, the first candidate battery is selected to be a candidate battery pack, and the candidate battery pack is provided corresponding to the battery exchange requirement. When the first candidate battery does not exist, judging whether the difference between the charge state of a second candidate battery in the corresponding candidate batteries and the charge state of a third candidate battery in the corresponding candidate batteries is smaller than or equal to a first preset threshold value or ratio, wherein the second candidate battery has the highest charge state in the candidate batteries and the third candidate battery has the next highest charge state in the candidate batteries. When the difference between the states of charge of the respective second and third battery candidates is less than or equal to a first predetermined threshold or ratio, the second and third battery candidates are selected to be a battery candidate set, and the battery candidate set is provided corresponding to the battery exchange request. When the difference between the state of charge of the respective second candidate battery and the state of charge of the respective third candidate battery is not less than or equal to the first predetermined threshold value or ratio, the second candidate battery is excluded from the candidate batteries and the first selected operation is re-performed. A battery power station of an embodiment of the invention has a battery housing system including a plurality of batteries, an energy module for charging the batteries, and a processing unit. The processing unit is coupled to the battery storage system and the energy module and receives a battery exchange request. The processing unit obtain
