摘要:
This invention provides a chemical cell equipped with a safety mechanism which can restrict an abnormal reaction of a cell and can prevent in advance gas explosion, etc., of the cell. The chemical cell 4010 comprises a cell reaction portion 4015, a positive pole terminal 4016 and a cell case 4041 functioning also as a negative pole terminal. A driving member 4021 responsive to a gas pressure or reaction heat at the time of the abnormal reaction includes a retention mechanism 4025 having a flexible member 4251 which cuts off a current and maintains this state. It also includes a gas discharge member. The driving member 4021 preferably short-circuits the positive pole terminal 4016 and the cell case 41 after the current is cut off, and preferably includes a valve member 4301 for closing a gas passage 4047 again after the gas is discharged (see FIG. 40 ).
摘要:
A large number of rechargeable unit cells connected in series forming a combination battery are divided into groups of cells, each group including several cells, preferably, three to five cells. Voltage unevenness among the cells in each group is eliminated by operation of a voltage balancer device connected to each group of cells. The voltage balancer device includes a circuit for equally dividing a terminal voltage of the group of cells and obtaining an average voltage among the cells. The average voltage is compared with an individual cell voltage, and the cells having a voltage higher than the average voltage are discharged so that all cell voltages in the group become equal. A plurality of the battery modules each including the group of cells and the voltage balancer device are connected in series to form a single combination battery, and voltage unevenness among the battery modules are controlled by another voltage control device. The voltage unevenness among cells in a group may be eliminated by charging a capacitor from cells having a higher voltage and charging cells having a lower voltage from the charged capacitor. Thus, the voltage unevenness among the combination battery cells is eliminated by a simple and inexpensive device.

When an arriving electric vehicle arrives at a car park with parking spaces, a parking state detection means in a parking and power charging system detects the presence of empty parking spaces. An assignment means assigns a ranking of charging performance to each detected empty parking space so that the empty parking space having the charging device of a higher charging performance has a higher ranking of charging performance on the basis of descending order of charging performance of the charging devices. A communication means obtains vehicle parameters of the arriving electric vehicle. A parking space instruction means instructs the arriving electric vehicle to move to and be parked in the empty parking space having the ranking of charging performance selected on the basis of the vehicle parameter such as necessity to charge or degree to easily charge the on-vehicle battery mounted on the arriving electric vehicle.

In a transflective liquid crystal display device, assuming that a narrower angle among angles formed by the initial liquid crystal alignment direction of a liquid crystal layer, and the projection direction of a pixel electrode of a transmissive unit is θt and that a narrower angle among angles formed by the initial liquid crystal alignment direction of the liquid crystal layer, and the projection direction of a pixel electrode of a reflective unit is θr, (1) when the liquid crystal layer possesses a positive-type liquid crystal, the relation of θt>θr is satisfied, and (2) when the liquid crystal layer possesses a negative-type liquid crystal, the relation of θr>θt is satisfied. The relations are satisfied by slanting or bending at least one of the pixel electrodes, and the reflectivity is improved.
