  • a lithium ion battery remains at a temperature of below 40° C. Overheating can result from various causes, such as damage to the battery, a short circuit, overcharging, application of reverse polarity, or exposure to a high ambient temperature.
  • the circuitry in power storage system 200 will, in certain embodiments, turn off power storage system 200 when the temperature reaches an unsafe level, such as 55° C. in one example.
  • capsule 217 may be activated in one of two ways.
  • a polymer fiber material polymorph
  • Polymorph is a non-toxic, biodegradable polyester with a low melting temperature of about 60° C. Other materials may be used, with melting temperatures between 55° C. and 65° C.
  • electrical contact is made between them. This contact ignites an explosive material within capsule 217. The explosion that results sends flame retardant material through the interior of power storage system 200 to extinguish the fire.
  • the flame-retardant materials used in capsule 217 may include phosphorous, carbon dioxide, powdered graphite, copper powder, and/or sodium carbonate, as non-limiting examples.
  • capsule 217 has a casing that is also constructed of the micrometer sized polymorph fibers that together form a heat-sensitive polymer coating. In the presence of sufficient heat, the polymorph fibers in the coating of capsule 217 will melt. With the interior of capsule 217 thus exposed to the heat, this then ignites a fuse within capsule 217, which is in communication with the explosive that is then ignited. Again in this case, the flame-retardant material is sent throughout the power storage system 200 by the explosion, thereby extinguishing the fire and preventing any further fire or electrocution hazard that results from the overheat condition.
  • Figs. 4A-4C illustrate one or two power storage systems 200 interconnecting with an enclosure 500.
  • An enclosure of this type may be employed, for example, on a powered vehicle such as a moped in order to securely house power storage systems 200 while the vehicle is in motion.
  • the high walls of enclosure 500 serve to prevent the power storage systems 200 from becoming dislodged during movement of the vehicle, and also serve to prevent any contact with the electrical connections by a conductor or the user while the system is in use.
  • FIGs. 5-5E illustrate a docking station 400 that allows the side-by-side mounting of up to four power storage systems 200.
  • Alternative embodiments of docking station 400 may allow for fewer or more power storage systems 200 to dock.
  • Docking station 400 includes a top cap 402 to receive the power storage systems 200 that fits onto terminal housing 404A. Endcaps 404B provide support for docking station 400. Electrical interconnection with power storage systems 200 occurs at receptor terminals 405A, which mate with power contacts 205B.
  • Docking station 400 further includes secondary power switch 406C, USB ports 407, inlet 412, vent slots 414 for cooling, and outlet socket 415.
  • FIGs. 6-7B illustrate a configuration with four power storage systems 200 connected directly to a docking station 400.
  • Figs. 8-8A illustrate a configuration with eight power storage systems 200 connected to a docking station 400, with four of the power storage systems 200 attached directly to the docking station 400, and each the other four power storage systems 200 attached at the top of one of the other four power storage systems 200.
  • Figs. 8B-8C show a similar configuration with twelve power storage systems 200 arranged in three layers of four each.

Abstract

La présente invention concerne un système de stockage et de génération d'énergie qui est modulaire, portable, empilable, connectable électriquement, interchangeable et personnalisable par rapport aux interconnexions entre elles. Les connexions électriques sont agencées de telle sorte qu'elles ne sont pas exposées à l'utilisateur lors de l'utilisation, empêchant ainsi des courts-circuits ou des chocs électriques accidentels. Les systèmes de stockage et de génération d'énergie peuvent être utilisés ensemble ou séparément pour fournir à la fois une puissance en courant continu puis convertir à une alimentation électrique en courant alternatif pour un équipement électrique se trouvant à des emplacements distants. Différentes configurations permettent l'adaptation du système à différentes exigences de tension et d'intensité pour diverses applications.
