Embodiment Construction

[0054] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not constitute a conflict with each other.

[0055] The battery is a basic and commonly used DC power supply in electronic equipment, and it has a limited capacity. Therefore, the output voltage and remaining capacity of the battery must be monitored in real time to prevent system instability or abnormality caused by overload. Generally, in the prior art, such as figure 1 As shown, the voltage value V_AD is sampled by means of resistor di...

Abstract

A monitoring control method and system (10) for the load capability of a battery. The system comprises a control unit (11) and a measurement load unit (12). The control unit and the measurement load unit are respectively connected in parallel to a battery (20) to be tested. The measurement load unit comprises a measurement load (121) and a measurement load switch drive circuit (122) connected to the measurement load. The measurement load switch drive circuit is connected to the control unit, and is used for receiving a first control signal sent by the control unit and controlling, according to the first control signal, the measurement load to be connected or disconnected to the battery. By means of the monitoring control method and system for the load capability of a battery, the floating voltage of the battery can be effectively avoided, the accuracy of the voltage detection of the battery can be improved, and the remaining capacity of the battery can be more stably displayed.

Description

technical field [0001] The present invention relates to the technical field of battery monitoring, in particular to a method and system for monitoring and controlling battery loading capacity. Background technique [0002] As a basic DC power supply in electronic equipment, the battery must be monitored in real time for its output voltage and remaining capacity to prevent system instability or abnormality due to overload. [0003] in such as figure 1 In the prior art shown, the voltage value is sampled by means of resistive voltage division, and then digital-to-analog conversion is performed to calculate the output voltage value of the battery, and finally the remaining capacity of the battery is estimated according to the output voltage of the battery and the charge-discharge curve of the battery . [0004] In the process of realizing the present invention, the inventor found that there are at least the following problems in the prior art: the prior art does not consider ...
