A container energy storage system is provided in this disclosure. The system includes a container and a plurality of functional assemblies. The container includes a container frame and a bottom plate. The container frame is formed a plurality of openings and a hollow main body. The bottom plate is disposed at the bottom of the container frame and is fixedly connected to the container frame. The functional assemblies are disposed in the hollow main body and located above the bottom plate.

An Electric car Power Boaster System, includes 12V Dynamo 4,Pulley 1, Belt 2, Pulley 3, DC-AC Inverter 6, 12V reservoir battery 5, 48 v Lithium battery charger 7 in symbiotic operation the with 48V lithium battery 8, 48V electric brush-less motor 9, Drive Unit 10, to form the Electric car Power Boaster system. When the car is driving, it spins the Dynamo 4, and the Dynamo connected to the DC reservoir 5 charges and store power until when needed. When the Lithium battery depleted during driving, the Inverter 6 and the 48V lithium battery charger 7 which are connected to the dc battery reservoir 5 is switch ON, this charges the depleted 48 v lithium battery fast enough, acting as a mobile charging station for another round of trip.

A terminal case configured to effectively estimate the life or degradation of a secondary battery as the secondary battery degrades includes a housing that can be coupled to the secondary battery, a plurality of normal mode terminals disposed on a first surface of the housing and a plurality of measurement mode terminals disposed on a second surface of the housing. The housing is configured to be coupled to the secondary battery with either the first surface or the second surface facing the secondary battery, such as by rotation of the housing about an axis passing through a center of two surfaces of the housing that are parallel to one another and perpendicular to both the first and second surfaces of the housing.

A battery system includes a battery receiving device and a plurality of battery units. Each battery unit can be coupled bidirectionally and inductively to one another and/or to the receiving device for charging/discharging. The receiving device can be connected to an external electrical energy source and/or sink. Each battery unit includes a coil unit. The receiving device has a storage seat for each battery unit removable with a magnetically complementary connectable coil unit for inserting/removing a battery unit without tools. The coil unit has a single coil which is substantially shaped as an elliptical, elongated flat coil, arranged in a half-shell housing and embedded in a ferrite core half-shell of ferrite elements, with a coil unit ratio of thickness to length/width of at least 1:5. The coil unit of the battery unit and receiving device are formed mechanically separable with a maximum distance between the coil units of 110 mm.

In certain embodiments, a system includes a belt for mechanically linking multiple energy storage cells together, wherein the multiple energy storage cells are grouped into at least first and second energy storage packs, each energy storage pack including at least one energy storage cell, the at least one energy storage cell of the first energy storage pack having a different energy storage characteristic from the at least one energy storage cell of the second energy storage pack. The system further includes an operational zone for receiving an energy storage pack and establishing an electrical connection between the received energy storage pack and an electrical device, and an actuator operable to move the multiple energy storage cells together to thereby dispose the first energy storage pack in the operational zone to establish the electrical connection with the electrical device.
