Abstract

A remote monitoring system for a battery module of an electric vehicle timely monitors the battery module of the electric vehicle mainly through a detection recorder provided in the electric vehicle. The detection recorder records the physical and electrical variables of the battery module and sends the data to the remote system through a communication unit. If the recorded data contains an abnormal condition of the battery module, the remote system wirelessly sends a signal through the telecommunication equipment; for example, through a wireless base station, a message telling a fault is sent to the receiving end of the user who in advance registers, reminding the user of overhauling the vehicle as soon as possible or inform the user of the vehicle'"'"'s condition for the car owner'"'"'s driving safety.

Claims

1. A remote monitoring system for a battery module provided in an electric vehicle, monitoring the battery module provided in the electric vehicle through a detection recorder and sending a detection signal, comprising:

a detection recorder provided in the electric vehicle to monitor the battery module in the electric vehicle, record physical and electrical variables of the battery module, and send data comprising the physical and electrical variables;

a control unit electrically connected to the detection recorder to control and send the data containing the physical variable;

a communication unit provided with an emitter that sends a signal converted from the data sent by the control unit;

thus, the signal sent by the communication unit serving as a basis on which the remote system reminds the vehicle'"'"'s user of overhauling as soon as possible or tells the user the vehicle'"'"'s condition for the car owner'"'"'s driving safety.

2. The remote monitoring system for a battery module provided in an electric vehicle according to claim 1, wherein the control unit controls the detection recorder in a manner of sequence, matrix, and timing to detect each monomer charging cell.

3. The remote monitoring system for a battery module provided in an electric vehicle according to claim 1, wherein the data of physical and electrical variables of the control unit comprises a random group of options of discharged and charged voltage and current as electrical characteristics, a working temperature during charging and discharging, and numerical data regarding an internal impedance variation in the battery.

4. The remote monitoring system for a battery module provided in an electric vehicle according to claim 1, wherein the signal converted by the communication unit is sent by the emitter in a random manner of instant transfer, fixed-time transfer, or conditional transfer.

5. The remote monitoring system for a battery module provided in an electric vehicle according to claim 1, wherein the control unit is controlled by a switch unit and may output a status data to a display element.

6. The remote monitoring system for a battery module provided in an electric vehicle according to claim 5, wherein the switch unit serves as a working occasion to set up the control unit.

7. A remote monitoring system for a battery module provided in an electric vehicle, monitoring the battery module provided in the electric vehicle through a detection recorder and sending a detection signal, comprising:

at least one electric vehicle, comprising

a detection recorder monitoring the battery module in the electric vehicle, recording physical and electrical variables of the battery module, and sending data containing the physical and electrical variables;

a control unit electrically connected to the detection recorder to control and send the data containing the physical and electrical variables;

a communication unit provided with an emitter that sends a signal converted from the data sent by the control unit;

at least one base station receiving and sending the signal transmitted by the communication unit;

a remote monitoring center receiving and replying a signal transmitted by the base station;

thus, the signal sent by the communication unit, through the base station, serving as a basis on which the remote system reminds the vehicle'"'"'s user of overhauling as soon as possible or tells the user the vehicle'"'"'s condition for the car owner'"'"'s driving safety.

8. The remote monitoring system for a battery module provided in an electric vehicle according to claim 7, wherein the control unit controls the detection recorder in a manner of sequence, matrix, and timing to detect each monomer charging cell.

9. The remote monitoring system for a battery module provided in an electric vehicle according to claim 7, wherein the data of physical and. electrical variables of the control unit comprises a random group of options of discharged and charged voltage and current as electrical characteristics, a working temperature during charging and discharging, and numerical data regarding an internal impedance variation in the battery.

10. The remote monitoring system for a battery module provided in an electric vehicle according to claim 7, wherein the signal converted by the communication unit is sent by the emitter in a random manner of instant transfer, fixed-time transfer, or conditional transfer.

11. The remote monitoring system for a battery module provided in an electric vehicle according to claim 7, wherein the control unit is controlled by a switch unit and may output a status data to a display element.

12. The remote monitoring system for a battery module provided in an electric vehicle according to claim 11, wherein the switch unit serves as a working occasion to set up the control unit.

13. The remote monitoring system for a battery module provided in an electric vehicle according to claim 7, wherein when the signal received by the base station indicates that the battery module is normal, it may be neglected by setting.

14. The remote monitoring system for a battery module provided in an electric vehicle according to claim 7, wherein the base station receives the signal from the battery module and the remote monitoring center informs and asks the base station to send a reply signal to the electric vehicle'"'"'s register.
