    Abstract: A vehicular lead storage battery according to the present invention includes a battery container provided with at least one cell chamber; and a cover plate 1 for covering an upper opening of the battery container. A guide path 8 for discharging gases within a cell chamber to the outside is formed in the cover plate 1. The guide path 8 includes a first guide portion 9B for horizontally guiding gases from the cell chamber; a second guide portion 9C connected to the first guide portion 9B to downwardly guide the gases from the first guide portion 9B; and a third guide portion 10A connected to the second guide portion 9C to horizontally guide the gases from the second guide portion 9C and discharge the gases from an exhaust vent 4K formed in the cover plate 1 to the outside. A corner portion 9K is formed by the first guide portion 9B and the second guide portion 9C, and a corner portion 10K is formed by the second guide portion 9C and the third guide portion 10A. The guide path 8 is formed so that the angle θ of a straight line L having internal contact with the two corner portions 9K and 10K from a horizontal line is greater than the maximum angle of inclination at which the inclined angle of a vehicle is maximum during driving on a sloping ground.

    Abstract: A battery charging apparatus for a vehicle includes a driver, a position detector, and a controller. The driver includes switching elements to convert three-phase AC power outputted from a winding of each phase of a stator of a three-phase AC generator into DC power to supply the DC power to a battery. The position detector is configured to output a position detection signal indicating a position of a rotor of the three-phase AC generator. The controller is configured to control the switching elements to be switched between an energized state and non-energized state. The controller is configured to have a maintenance period during a period until next input of the position detection signal if the period exceeds an energization period. The switching elements are to be maintained in the maintenance period in the energized state or non-energized state immediately before the period exceeding the energization period.

    Abstract: A battery charging apparatus includes a position sensor for outputting a position detection signal, a sensor for detecting an output current or voltage of a predetermined phase, a regulator for supplying DC power obtained by rectifying three-phase AC from the generator to a battery, and an inverter control section for executing energization control of the respective switching elements of the regulator based on a phase of an induced voltage of the generator calculated on the basis of the position detection signal. The inverter control section inputs a revolution speed signal Ne of the generator, the position detection signal Tp, and either output signal out of a current signal or a voltage signal detected by the sensor, and estimates an error of an attaching position of the position sensor with respect to the induced voltage of the predetermined phase based on the position detection signal and the output signal.
