CCCV charging is applied to a lithium ion secondary battery. During CC charging, a transition point Ta appears in temperature rise gradient when battery temperature rises along with the charging, and with the transition point Ta being a border, a temperature rise gradient in an initial T1 period is steeper than a temperature rise gradient in a T2 period following the T1 period. Based on charging time tT corresponding to timing at which the transition point Ta appears after start of the CC charging from a condition of the SOC of 0%, changeover time ts is set in a range of tT≦ts≦(tT×1.2). The CC charging is performed at a first current value until changeover time tS elapses after its start, and after the changeover time ts elapses, the CC charging is performed with a second current value larger than the first current value.

A power inverter control device is designed to control a neutral point clamped power inverter apparatus including first to fourth self-extinction elements sequentially connected in series between two end terminals of a power supply having an intermediate terminal, four freewheeling diodes connected in parallel with the self-extinction elements in a direction opposite thereto, a series circuit of first and second clamping diodes, connected in parallel with a series circuit of the second and third self-extinction elements in a direction opposite thereto and having a node connected to the intermediate terminal of the power supply. The control device includes a circuit for generating a first PWM control signal having a pulse width corresponding to a load current, and a PWM control circuit for converting the first PWM control signal into a second PWM control signal having a pulse width equivalent to the sum of the pulse width of the first PWM control signal and a width corresponding to one of turn-on and turn-off periods of each of the self-extinction element, and supplying the second PWM control signal to the first to fourth self-extinction elements.

A control system for a pulse-width modulation controlled power converter composed of self-turn-off devices. The control system includes a voltage command value generator for the power converter, a carrier wave generator and a circuit for correcting at least one of the voltage command value and the frequency of the carrier wave to generate as a corrected voltage command value and a corrected carrier wave. The control system further includes a gate pulse signal generator for receiving a first signal and a second signal and for comparing the first and second signals to generate gate pulse signals to the self-turn-off devices for controlling the power converter based on a comparison result. The voltage command value is taken as e (-1.ltoreq.e.ltoreq.+1), and a level setting value is taken as E.sub.a (0
摘要:
When a medium casing is properly inserted, a first pair of projections and a second pair of projections are passed through between a first bottom surface and a second bottom surface of a chassis in the moving direction and are thus prevented from coming into contact with the first and second bottom surfaces, thereby allowing for smooth insertion of the medium casing. In contrast, when the medium casing is inserted improperly from its wrong end, one of the projections on the lower surface of the medium casing comes into abutment with the second bottom surface of the chassis near the opening. Accordingly, an improperly inserted medium casing can be prevented from being inserted any further at an early stage of the insertion process.
