一种收集、充电及分配机器网络收集、充电及分配便携式电能存储器件(例如，电池组、超级电容器或超电容器)。在车辆处于一收集、充电及分配机器或诸如一钥匙圈或一用户之其他无线器件的其他经授权之外部器件附近的情况下，使一关闭或锁定的空便携式电能存储器件收容空间自动解锁、拉开插栓或打开，以允许容易且便利地接取该等车辆内之空便携式电能存储器件收容空间。再者，在该便携式电能存储器件收容空间处于使该收容空间解锁之另一所要状态下的情况下，诸如，在该收容空间中具有具低于一特定临限值之一充电位准的一便携式电能存储器件，将同样地使该收容空间自动解锁、拉开插栓或打开。

A network of collection, charging and distribution machines collect, charge and distribute portable electrical energy storage devices (e.g., batteries, supercapacitors or ultracapacitors). To allow easy and convenient access to empty portable electrical energy storage device compartments within the vehicles, if the vehicle comes within the vicinity of a collection, charging and distribution machine or other authorized external device such as a key fob or other wireless device of a user, an empty portable electrical energy storage device compartment that is closed or locked, is unlocked, unlatched or opened automatically. Also, if the portable electrical energy storage device compartment is in another desired state to have the compartment unlocked, such as having a portable electrical energy storage device in the compartment that has a charge level below a particular threshold, the compartment will likewise be unlocked, unlatched or opened automatically.
