    摘要： An embodiment relates to a method for predicting a voltage dip in a vehicle electrical system before a planned start of a load in a motor vehicle. The embodiment operates to ascertain a value of supply current expected to be required after the start of the load. An electrical voltage source and an energy store connected in parallel to a voltage source via the vehicle electrical system provide the supply current for operating the load. The energy store blocks a charge current into the energy store or blocks a discharge current out of the energy store based on a vehicle electrical system voltage of the vehicle electrical system being greater than a maximum value. Based on an instantaneous value of the vehicle electrical system voltage, the embodiment further ascertains a proportion of the supply current that the voltage source generates as a source current without the energy store until the vehicle electrical system voltage has fallen to the maximum value.

    摘要： The present invention concerns a battery monitoring system for monitoring a plurality of batteries serially connected to form a string. The battery monitoring system includes a number of probes connected to at least a portion of the string, a daisy chain bus having a select channel for serially interconnecting the probes, the bus having other, parallel channels for data communication and power, and a system server. The probes each have a sensing module and a communication module. The sensing module senses characteristics of at least a portion of the string, such as voltage or current. The communication module receives the sensed characteristics and converts them into digital form for broadcast to the system server over the bus. The communication module of the probes have a memory for storing an address assigned to the corresponding probe upon reception of an initialization signal sent by the system server via the bus. In order to readdress all of the probes, a reset signal is transmitted to all of the probes. The probes clear the present address, and wait until they are selected through the select channel. Once the probe has been selected, it receives an address from the system server, stores the address in its memory, acknowledges this to the system controller, and sends a signal on the select channel to the next probe. Accordingly, initialization of a battery monitoring system is easily performed. The invention also lies in an interface device for use with a battery monitoring system.

    摘要： In order to maintain normal states of machines during cutoff of electric power, an uninterruptible power supply (UPS) is required for a short time before a power generator starts to send out electric power. For normal functioning of a UPS, it is necessary to periodically detect the state of each battery thereof. In addition to measuring the variation of voltage and current of a battery by using a microprocessor, a sensor, and an analog-to-digital converter (ADC), the variation of voltage versus time (i.e., the voltage drop rate) of the battery during discharge is also measured. In other words, the voltage drop rate of a battery is measured as a standard for determining whether the battery is applicable to the UPS.

    摘要： Methods are described for determining the state of charge and/or the operability of a charge accumulator using estimates, the information, which is obtained at at least two different operating points or operating conditions of the energy accumulator, being taken into account in the estimates. The estimates are carried out with regard to an instantaneous and/or future state of charge and/or an instantaneous and/or future operability of the charge accumulator. Different methods are executed, depending on the operating point or operating condition. The methods are usually run in a processor of a control unit.
