Power monitoring device for batteries of automobile

Abstract

The invention relates to a power monitoring device for batteries of an automobile. The power monitoring device comprises a device box, and is characterized in that battery detection ends are arranged on the device box, and input ends of the battery detection ends are respectively connected with an input end of a master control unit assembly and an input end of a sub-control unit assembly. A data communication end of the master control unit assembly and a data communication end of the sub-control unit assembly are jointly connected with a battery control assembly, and a signal monitoring end of the battery control assembly is connected with a display assembly. The power monitoring device has the advantages that the master control unit assembly, the sub-control unit assembly and the battery control assembly are effectively matched with one another, so that various technical parameters of voltages, currents, loads, temperatures and the like of the batteries of the automobile can be effectively monitored, safe use degrees of the batteries of the automobile are increased, and troubleshooting can be effectively carried out; the power monitoring device is provided with a bus output end, an address digital output end and a power signal output end in a matched manner, so that monitoring signals can be transmitted conveniently, and necessary guarantee for function extension can be provided.

Description

technical field [0001] The invention relates to a monitoring device, in particular to a vehicle battery power monitoring device. Background technique [0002] Valve-regulated sealed lead-acid battery is the most commonly used battery for automobiles. Due to the complex electrochemical reactions inside the battery, the relationship between the electromotive force of the battery and the remaining power of the battery is not linear. The traditional method for predicting the remaining battery capacity is generally to measure the electromotive force of the battery and estimate the remaining battery capacity linearly. Although it is simple, the error is relatively large. [0003] At the same time, various performances of the battery including voltage, charge, current, temperature, etc. cannot be effectively monitored. Moreover, it is impossible to better monitor the working states of the battery pack or battery cells such as charging, discharging, and load, which is not conducive...

Problems solved by technology

The traditional method of predicting the remaining battery capacity is generally to measure the electromotive force of the battery and estimate the remaining battery capacity linearly. Although it is simple, the error is too large

[0003] At the same time, the various performances of the battery, including voltage, charge, current, temperature, etc., cannot be effectively monitored.

Moreover, it is impossible to monitor the working status of the battery pack or battery cells such as charging, discharging, and load, which is not conducive to the safe use of automotive batteries.
