Abstract

A battery monitoring system includes a detector and a supervisor connected to the detector. Wherein, pluralities of sensors of the detector respectively disposed on battery cells of the battery for at least correspondingly detecting voltage and temperature signals of the battery cells. Subsequently, the aforementioned signals are transmitted to a central processor for a separate conversion into accessible and distinguishable data applied to compare with a predetermined threshold. Finally, the compared results would be shown on the supervisor for users to realize the physical state of each battery. The central processor friendly reacts to the compared result under the irregular state and emits a warning signal to the supervisor, for which to promptly carry out a warning action.

Claims

1. A battery monitoring system for monitoring a healthy status of a using battery;

said battery being formed by a plurality of battery cells that are monitored by said monitoring system;

wherein, said monitoring system comprising;

a detector disposed in said battery including an integrator, and a central processor as well as a plurality of sensors respectively connected to said integrator;

wherein, said sensors being correspondingly disposed on said of each battery cells for respectively sensing a voltage signal and a temperature signal thereof;

wherein, said integrator integrating and transmitting said voltage and temperature signals to said central processor;

said central processor having a converter and a CPU connected to said converter, so that said converter receiving said voltage and temperature signals transmitted from said integrator for which to convert said signals into separate voltage and temperature data;

said CPU previously saving a predetermined value for comparing with said voltage and temperature data; and

a supervisor connected to said CPU for displaying a compared result from said CPU that compares said voltage data and said temperature data with said predetermined value, and said CPU friendly reacting to an irregular state of said compared result and emitting a warning signal to said supervisor for which to promptly carry out a warning.

2. The monitoring system as claimed in claim 1, wherein, a sensor is correspondently installed on each of said battery cell for further detecting a current signal of said battery cell, and said current signal that is detected by said sensor would be directly transmitted to said central processor for being converted, compared and differentiated.

3. The monitoring system as claimed in claim 1, wherein, said supervisor includes a controller for receiving signals from said CPU and a displayer connected to said controller.

4. The monitoring system as claimed in claim 3, wherein, said controller has a receiving and transmitting unit for receiving signals from said CPU and a processing unit connected to said receiving and transmitting unit.

5. The monitoring system as claimed in claim 3, wherein, said displayer adopts a twinkling light for presenting an abnormal status.

6. The monitoring system as claimed in claim 1, wherein, a plurality of batteries form a battery pack, and said batteries are interconnected with each other.

7. The monitoring system as claimed in claim 2, wherein, a plurality of batteries form a battery pack, and said batteries are interconnected with each other.
