    摘要： A method and apparatus is provided for determining when a battery, or one or more batteries within a battery pack, undergoes an undesired thermal event such as thermal runaway. The system uses an optical fiber mounted in close proximity to, or in contact with, an external surface of the battery or batteries to be monitored. A source of light is optically coupled to the input facet of the optical fiber and a detector optically coupled to the output facet of the optical fiber. Battery health is determined by monitoring the light transmitted through the optical fiber.

    摘要： A simplified cell design is provided for a battery utilizing the 18650 form-factor, the simplified cell design reducing manufacturing cost, battery weight and the risk of shorting between the battery case and the battery terminal. In the cap assembly of the disclosed battery, the safety vent element, which is recessed relative to the top of the cell case, also serves as the battery terminal. Additionally, the insulating gasket positioned between the cell case and the cap assembly is designed to cover a large portion of the outer surface of the safety vent/battery terminal.

    摘要： Methods and systems for decreasing costs (expense, mass, and/or cure time) associated with use of adhesives when assembling modularized components, particularly for assemblies having many elements such as for example battery modules used in electric vehicles. The methods and systems enable use of high-wettability adhesives (defined generally in this application as low viscosity and/or low surface tension adhesives) for assembling such modularized components. A first method including (a) dispensing a high-wettability adhesive into a first module fixture populated with a plurality of elements wherein the first module fixture provides a plurality of bonding wells with each bonding well accepting a first portion of one or more of the elements with the module fixture including one more apertures communicated with one or more of the bonding wells, the adhesive being selectively curable upon application of a curing modality; (b) applying the curing modality selectively to a first portion of the dispensed adhesive in a seal zone, the seal zone including one or more regions surrounding the apertures wherein the dispensed adhesive in the seal zone is sufficiently cured to inhibit significant quantities of the adhesive from emerging from the apertures while the adhesive continues to be dispensed into the module fixture wherein the curing modality is not applied to a second portion of the adhesive outside of the seal zone; and (c) applying the curing modality to the second portion of the dispensed adhesive.

    摘要： A method and apparatus for simplifying battery pack encapsulation is provided. The battery pack includes a pair of complementary housing members with each housing member including a plurality of cell contraints into which the ends of corresponding battery cells are inserted during assembly. One or both housing members also include at least one, and preferably a plurality, of raised encapsulant injection ports. The raised encapsulant injection ports are designed to extend above the surface of the respective housing members and beyond the injected encapsulation material, thus ensuring that the ports remain open after encapsulation material injection.

    摘要： An overcharge protection device (OPD) is provided that may be used alone, or in combination with conventional charging protection systems, to protect a battery pack from the occurrence of a potentially damaging overcharging event. The OPD is designed to be coupled to, and interposed between, the terminals of the battery pack. During normal system operation, the OPD has no effect on the operation of the charging system or the battery pack. During an overcharging event, if overcharging is not prevented by another conventional system, the OPD of the invention creates a short across the terminals of the battery pack causing a battery pack fuse designed to provide battery pack short circuit protection to blow, thereby interrupting the current path from the charger to the battery pack and preventing the battery pack from being overcharged.

    摘要翻译： 提供了可以单独使用或与常规充电保护系统组合使用的过充电保护装置（OPD）来保护电池组免受潜在的破坏性过充电事件的发生。 OPD被设计成耦合到电池组的端子并插入在电池组的端子之间。 在正常的系统操作过程中，OPD对充电系统或电池组的操作没有影响。 在过充电事件中，如果不是由另一传统系统防止过充电，则本发明的OPD在电池组的端子之间产生短路，导致设计成提供电池组短路保护的电池组熔断器，从而中断电流 从充电器到电池组的路径，并防止电池组过充电。
