摘要： The invention concerns a method for controlling a motor vehicle electric circuit consisting in breaking down the circuit architecture into perimeters to be studied containing at least an electric element receiving and transmitting current, in taking into account only the electric connections common to the different perimeters and differentiated into supply connections and earth connections, and in detecting supply or earth feedback on these connections by injecting stabilised voltages on certain connections for reading the voltage levels on the connections to be controlled. The method further consists in measuring the maximum current that can pass through a feedback, on a supply or earth connection. The invention also concerns a method for implementing the method.

摘要： A fault detection method is disclosed for a motor vehicle charging system including a generator (14) and an electrical component (19) coupled to receive electrical current from the generator (14). In one embodiment, the method comprises sensing a first voltage at an output of the generator (14) and sensing a second voltage at the electrical component (19) and, if the first voltage and the second voltage differ by more than a predetermined amount, reducing or suspending output of electrical current from the generator (14). One advantage of the method disclosed herein is in its ability to diagnose a fault in an electrical connection at the output of a motor vehicle generator, where the fault manifests itself as a high resistance connection.

摘要： A battery charge control device (1) is capable of detecting a gassing state in a battery without using a temperature sensor. Under condition of charging the battery (5) with a charging current, when a terminal voltage Vi of the battery (5) monitored by the device exceeds a threshold value, a temporary-gassing detecting unit (23) informs a voltage regulation calculating unit (24) that the battery (5) is in course of reaching its gassing state. The voltage regulation calculating unit (24) calculates a charging rate of terminal voltage Vi of the battery (5) while it is in course of reaching the gassing state. When the calculated changing rate exceeds a preset decision value, a gassing detecting unit (25) judges that the battery (5) has just reached the gassing state. A decision value renewing unit (27) changes the decision value corresponding to the charging current.

摘要： This meter comprises means for measuring the discharge current and terminal voltage of a battery; a data table showing the values of available capacity which are expressed by combinations of the values of different discharge currents, and the values of the terminal voltages, and prepared on the basis of the values measured in advance; storage means for storing the data table; and means for displaying on a display the value of the available capacity by reading the capacity from the storage means in accordance with the terminal current and voltage values when the battery is in use. The value of the available capacity is defined as the ratio of the total time during which the discharge with a constant current is possible at from the initial voltage in the fully charged condition to the final voltage, and the remaining time during which the discharge of constant current is possible at from the value of the measured terminal voltage to the final voltage.

摘要： Current flowing into and out of a battery (1) installed in a vehicle (V) with the required cable (3) between one of the battery terminals and a reference point (8) on the vehicle is determined by measuring the voltage across the cable (3) and computing (22) the current from the digital value of the measured current. The resistance value of the cable can be known in which case the current is computed using Ohms low and a differential current sensor (30) can be used to respond to the voltage measured across the cable to accommodate for different ranges of current. In an embodiment where the cable (3) resistance is unknown, a reference current source (125) produces a known voltage (128) that is used to set the input value to an amplifier (111) of fixed gain for the voltage measured across the cable by controlling the output of a potentiometer (106) so that the amplifier output voltage can be set to match the reference current generator output voltage, thereby establishing the voltage output of the amplifier as a measurement of the current flow in the cable.
