    摘要： Disclosed herein are a methods and system for monitoring battery temperature and providing alerts when temperatures are abnormal, comprising: wirelessly receiving temperature measurement data from a single monobloc or a plurality of monoblocs that are electrically connected in series or parallel, wherein a temperature measurement data represent the temperatures inside each of said plurality of monoblocs; calculating a temperature value, TPDAVE, equal to an average of the temperature measurement data wirelessly received from all the plurality of monoblocs in a battery; calculating a high temperature difference, TPDH, as an absolute value of the difference between the highest monobloc temperature in the battery and the TPDAVE; calculating a low temperature difference, TPDL, as an absolute value of the difference between the lowest monobloc temperature in the battery and the TPDAVE; and establishing an alert when the TPDH is greater than a predetermined high temperature threshold.

    摘要： Described herein are methods for determining, based on actual crank conditions, an ability of a battery connected to an electric starter motor, to start an internal combustion engine, wherein the battery is a single monobloc or a plurality of monoblocs that are electrically connected in series or parallel. The method may comprise: receiving battery temperature data, representing a temperature of the battery at a time of cranking the internal combustion engine; receiving voltage data monitored from the battery, determining an instantaneous minimum voltage of the battery during the time of cranking the internal combustion engine; and determining a capability of the battery to crank the internal combustion engine based on the battery temperature data and the instantaneous minimum voltage of the battery.

    摘要： A battery monitor circuit, systems and methods are disclosed. The battery monitor circuit may comprise a voltage sensor, a temperature sensor, a processor for receiving a monitored voltage signal from the voltage sensor, for receiving a monitored temperature signal from the temperature sensor, and for generating voltage data and temperature data based on the monitored voltage signal and the monitored temperature signal, an antenna, and a transmitter. The battery monitor circuit may be configured for wirelessly communicating the voltage data and the temperature data to a remote device, via the antenna. In an exemplary embodiment, the battery monitor circuit is configured to be located external to the battery and wired electrically to the battery.

    摘要： A method of determining a reserve time of a monobloc includes detecting, by a voltage sensor, an end of discharge voltage of the monobloc after a deep discharge of the monobloc. The method further includes receiving, by a processor, the end of discharge voltage of the monobloc. The method further includes determining or receiving, by the processor, a duration of the deep discharge. The method further includes calculating, by the processor, a discharge reserve time of the monobloc based on the end of discharge voltage and the duration of the deep discharge.

    摘要： Described herein are method and systems for detecting an unauthorized removal of a battery. The system comprising: a battery monitor circuit attached to or embedded in the battery; a remote device, wherein the remote device stores instructions that when executed on the remote device cause the remote device to perform operations comprising: receiving, at the remote device, a wireless signal from the battery monitor circuit comprising voltage and temperature data; evaluating, by the remote device, whether the battery is in its expected location by confirming for each battery, which is expected to be present, whether there has been an unexpected interruption in the wireless signal from the battery; providing an alert notification when there has been an unexpected interruption in the wireless signal.

    摘要： A method for estimating a SOC of a battery electrically coupled to at least one of a load or a power source includes detecting, by a voltage sensor, voltages of the battery. The method further includes determining, by a processor, an average voltage of the battery by averaging the detected voltages of the battery over a predetermined period of time. The method further includes determining, by the processor, a present operating state of the battery based on at least one of the detected voltages of the battery. The method further includes determining, by the processor, a present SOC of the battery based on the present operating state of the battery and the average voltage of the battery. The method further includes transmitting, by the processor, the present SOC of the battery to an output device for outputting the present SOC of the battery.

    摘要： A method for determining a remaining life of a battery includes detecting, by a voltage sensor, multiple voltages of the battery. The method further includes detecting, by a temperature sensor, multiple temperatures corresponding to the battery. The method further includes receiving, by a processor, the multiple voltages and the multiple temperatures of the battery. The method further includes determining, by the processor, an amount of float life consumed during a float mode of the battery based on at least one of the multiple temperatures. The method further includes determining, by the processor, an amount of cycle life consumed during a discharge mode of the battery based on at least one of the multiple voltages. The method further includes calculating, by the processor, the remaining life of the battery based on at least one of the amount of float life consumed or the amount of cycle life consumed.
