  • Current detection circuit and voltage converter using the current detection circuit
    Patent number: 8149021
    Abstract: A first auxiliary switch circuit is connected to one terminal and a first terminal of a main switch circuit and generates a first auxiliary detection current. A second auxiliary switch circuit is connected to the other terminal and a second terminal of the main switch circuit and generates a second auxiliary detection current. A current adjustment detection circuit adjusts the first auxiliary detection current so that the potentials of the other terminal and the first terminal are equal and passes the first auxiliary detection current in a direction of receiving the current from the first auxiliary switch circuit and adjusts the second auxiliary detection current so that the potentials of the one terminal and the second terminal are equal and passes the second auxiliary detection current in a direction of outputting the current to the second auxiliary switch circuit, thereby generating a detection current being proportional to the output current.

  • Material for packaging cell, bag for packaging cell, and its production method
    Patent number: 7285334
    Abstract: A lithium battery comprises a pouch (4) and a lithium battery module (2) packaged in the pouch (4). The pouch (4) is formed from a battery packaging laminated structure (10). The laminated structure (10) has an outermost layer (11), a barrier layer (12) and an innermost layer (14), or an outermost layer (11), a barrier layer (12), an intermediate layer (13) and an innermost layer (14) superposed in that order. The outermost layer (11) is formed of a formable base material, the barrier layer (12) is formed of a impermeable base material having a barrier property, the intermediate layer (13) is formed of a formable base material and the innermost layer (14) is formed of a heat-adhesive base material.
