Abstract:
A refuse vehicle includes a chassis, a body assembly coupled to the chassis, the body assembly defining a refuse compartment, an electric energy system configured to store power and supply power to at least one of the chassis or the body assembly, and a power control system. The power control system is configured to measure one or more electrical attributes of at least one of the chassis and the body assembly and determine a power profile for at least one of the chassis and the body assembly, the power profile describing, based on a remaining power of the electric energy system, at least one of a length of time the refuse vehicle can continue to operate or a distance that the refuse vehicle can traverse. the power control system is further configured to control a function of a non-essential component of the refuse vehicle based on the power profile.
Abstract:
A power management system for a vehicle includes a first battery monitoring module configured to monitor a first state of charge (SOC) of a first battery of the vehicle. The first battery has a first nominal voltage. A second battery monitoring module is configured to monitor a second SOC of a second battery of the vehicle. The second battery has a second nominal voltage that is greater than the first nominal voltage. A control module is configured to, using a direct current (DC) to DC converter, selectively charge the second battery with power from the first battery until the second SOC of the second battery is greater than or equal to a predetermined SOC.
Abstract:
An optimization method of a power control logic for entering into an idle stop & go (ISG) mode comprises steps of: monitoring a state of charge (SOC) of a battery to detect a parasitic current of the battery by a battery sensor of a vehicle; transmitting a parasitic current flag to an engine control unit (ECU) when the battery sensor detects the parasitic current; and determining whether a device using standby power of the battery is installed and increasing a voltage of the battery via additional power control when it is determined that the device is installed.
Abstract:
A judgment device includes a residual capacity acquisition section adapted to obtain a remaining battery power of a battery as a power source of a printer, an arithmetic section adapted to calculate a predicted consuming capacity of the battery consumed by execution of a print job, and a judgment section adapted to judge whether or not the battery has the remaining battery power, with which the printer can complete the print job, based on the remaining battery power and the predicted consuming capacity.
Abstract:
A test system for testing a battery pack having a high voltage terminal, a low voltage terminal, first and second battery modules, and a master microprocessor is provided. The test system includes an inverter unit and a test computer. The inverter unit iteratively grounds the high voltage terminal and the low voltage terminal. The test computer sends a first message to the master microprocessor that requests first and second voltage values of the first and second battery modules. The master microprocessor sends a second message having the first and second voltage values to the test computer which determines a first voltage deviation value. The test computer sets a test flag to a predetermined pass value if the test computer received the second message and the first voltage deviation value is less than a first threshold voltage deviation value.
Abstract:
A method that monitors an electrical battery of a vehicle includes, consecutively, measuring a state-of-charge of the electrical battery at predetermined intervals, comparing the measured values of the state-of-charge of the electrical battery with a first predetermined threshold, and comparing a number of the measured values below the predetermined threshold to a predetermined number, in order to decide whether to replace or recharge the electrical battery, in order to avoid or remedy an immobilization of the vehicle.
Abstract:
A motor vehicle has a first energy store for the operation of multiple vehicle systems and a second energy store which, at least, provides the electrical energy needed to start the motor vehicle, and a control device. A method for testing a first energy store includes connecting the first energy store to a load having a lower impedance than the minimum total impedance of a parallel circuit composed of a fixed selection of the vehicle systems for a fixed time interval by means of the control device, measuring a voltage dropping on the first energy store by means of the voltage measuring device, at least once within the time interval, and outputting a signal by means of the control device if the voltage falls below a predefined limiting value,
Abstract:
A method of use for an electric energy store includes defining a set of states of the electric energy store. The method further includes defining at least one separation surface which separates a first subspace of first states of the electric energy store from at least one second subspace of second states of the electric energy store and detecting at least one influencing factor from the predefinable influencing factors and determining third states of the electric energy store if the electric energy store is used. The method includes estimating at least one state by evaluating at least one influencing factor, checking whether the at least one state is in a predefined subspace for the predefined time and changing use of the electric energy store such that the at least one state is in the predefined subspace at the predefined time based on the check.

An electronic device or tool including an indicator adapted to provide an indication when a predetermined amount of time of operation of the electronic device, for example about 10 minutes, remains in the power source. The indicator device indicates to a user that the user has a certain amount of time of operation of the electronic device before the electronic device will shut down and become inoperable.
Abstract:
A method for predicting a low battery voltage condition includes calculating a minimum battery capacity required to start an engine, determining a first capacity of a battery at a first time, determining a second capacity of the battery at a second time, and predicting, based on the first and second determined capacities, when a remaining capacity of the battery will be less than the minimum battery capacity. A control system programmed with the above method and a locomotive included the programmed control system are also described herein.
