  • Patent number: 10818957
    Abstract: Disclosed herein is a method of manufacturing a battery pack including a battery cell having an electrode assembly received in a battery case, made of a laminate sheet including a resin layer and a metal layer, together with an electrolytic solution. An upper case, a PCB, and a battery cell are simultaneously coupled to each other through a hot-melt process without using additional members, such as double-sided adhesive tape and a PCM case. In particular, a label can be removed from an embedded type battery pack. Consequently, it is possible to improve manufacturing efficiency and reduce manufacturing cost due to the reduction in the number of parts.

  • Patent number: 9817596
    Abstract: A non-volatile memory system and a method of managing the power of the same are provided. The non-volatile memory system includes a non-volatile memory configured to store a first mapping table comprising a list of a logical address and a physical address corresponding to the logical address with respect to a code region and a list of a logical address and a physical address corresponding to the logical address with respect to a general purpose (GP) region, and a controller configured to load the first mapping table from the non-volatile memory to a first memory and load the second mapping table from the non-volatile memory to a second memory. Power-up of the second memory is delayed with respect to power-up of the non-volatile memory system and the first or second memory is powered down if a condition is satisfied, so that power consumption of the non-volatile memory system is reduced.
