    摘要: The current-collecting lead for being welded to a collector welded to an upper portion of an electrode group and also to a sealing assembly of an cylindrical secondary battery includes: a flat surface part welded to the collector, and a top part formed to be curved and protrude approximately in the shape of a dome from the flat surface part and welded to the sealing assembly. A central opening is formed at a central portion of the top part. Around the central opening, a plurality of welding projections are formed to protrude toward the sealing assembly. The welding projections serve as welding spots to the sealing assembly. The top part is deformed by a pressing force from the sealing assembly to be brought into surface contact with a corner portion of a convex portion formed on a lower surface of the sealing assembly.

    摘要: To prevent the complete discharge of a battery connected to a load, a battery voltage of the battery is compared with a reference voltage, and a switch is activated to open an electrical connection between the battery and the load when the detected battery voltage falls below the reference voltage. To compensate for dynamic characteristics of the battery and the load, a battery current flowing through the battery is detected and a value of the reference voltage is continuously set according to the detected battery current. Similarly, a battery temperature of the battery also controls the reference voltage. Also, a timer may be provided to cause the switch to open the connection between the battery and the load only when the detected battery voltage remains below the reference voltage for a predetermined period of time.
