Description

Battery management method and system

The present invention relates to a battery management method and system, and more particularly to a battery management method and system for use in an electric vehicle by using an internet communication protocol.

Since the issue of environmental protection has been raised, more and more people are beginning to understand that the resources of the earth are not inexhaustible, so the discovery and research craving for energy alternatives continues to be carried out all over the world. However, there is still no efficient application solution available to date, and oil demand still accounts for the vast majority of our lives. The idea of Electric Vehicle (EV) has been proposed for a long time, and the actual products have been actually manufactured and sold on the market. The EV is a carrier that uses an electric motor as a source of propulsion. By using electricity as a propulsion for the car, the EV provides greater power and ease of operation and comfort compared to vehicles that traditionally use the Internal Combustion Engine (ICE). Despite this, pure EVs still have many shortcomings that cannot be solved at present, the most important of which is that they cannot load long-distance travel.

To overcome this problem, Hybrid Electric Vehicle (HEV) began to appear. This carrier combines the use of an ICE propulsion system with an electric propulsion system and thus provides special performance between conventional vehicles and EVs. However, due to the complexity of the HEV and the expensive manufacturing costs, it is still very difficult for the promotion of HEV in the market and the popularity of consumers.

At present, a concept of establishing a "battery station" has been proposed. The purpose of establishing a "battery station" is to enable EV users to directly charge the batteries in their EVs anywhere, without being limited to their own, just like the current gas station mode. As a result, the driving distance of the EV will be effectively extended. However, in such a system, the function of the battery station is to charge the battery, and this system must also be established under the premise that the EV has been widely popularized on the market. But for EV, the most important and expensive component is the battery, the core of the entire carrier, which provides the power to propel the carrier. If the battery's performance declines, you must buy another battery for the EV, otherwise the entire vehicle will become a scrap iron. Therefore, the promotion of EV still has many problems and obstacles.

Get the information stored in token 11. In the present embodiment, the battery exchange station 12 is a base station of the wireless network, but is of course not limited thereto. That is, other methods that can be used in this embodiment are also applicable. In addition, this IP address provides a specific identity identification (ID) for each battery 10, and thus enables a large number of battery 10 management modes.

However, the transmission of this information is not limited by the above method. When the EV 15 is driven into the battery exchange station 12 to replace the battery 10, the information of the battery 10 stored in the token 11 can also be read and collected by the battery exchange station 12 via a short-range wireless transmission method, such as radio frequency identification ( RFID), infrared transmission, microwave communication or any method that can be adapted for use in the present invention. More specifically, when the EV 15 is traveling on the road, the information of the battery 10 will be continuously transmitted to the battery exchange station 12, and when the user drives the EV 15 into the battery exchange station 12 to replace the battery, the battery exchange station 12 The status of the battery 10 can be last updated via the token 11. The information of the removed battery is transmitted to the management center 14 for overall control. Therefore, the management center 14 can immediately update the instant status of all the batteries 10 and find out if any damaged batteries are stored in the warehouse 13 or are currently being used in any EV 15. A notification can be sent to the battery exchange station 12 or the user at this time.

Through the configuration of the IP address, each battery exchange station 12 is able to recognize whether the battery 10 is qualified, that is, the battery 10 is accepted and approved by the battery exchange station 12. If the EV 15 with an unqualified battery enters the battery exchange station 12 and asks to replace the battery, the battery exchange station 12 will recognize and reject the request.

In addition, the present invention may also incorporate Global Positioning System (GPS) technology, GPS may be configured on each EV 15 to assist the user in locating and identifying adjacent battery exchange stations 12. In addition to providing the functionality of battery 10 exchange, the battery exchange station 12 can also provide maintenance and repair services and report back to the management center 14. Since the token 11 can detect the current state of the battery 10, when the battery 10 needs to be repaired or charged, the token 11 will actively send a warning to the user, so the user will have enough time, according to the GPS. The message is to find a viable battery exchange station 12.

Since the management center 14 also tracks and updates the instant status of all of the batteries 10, it can also be found which batteries 10 need to be replaced, repaired or charged, so that notifications can also be sent directly or indirectly to the tags embedded in the battery 10. 11, to remind users. As a result, the state of each battery 10 will be double-checked, so the effectiveness of monitoring and management will be greatly improved.

In summary, the present invention provides an integrated battery management system that can revolutionize the current transportation architecture, substantially reduce the loss of earth resources, and achieve a comfortable, convenient, and promising future. The concept of the present invention actually solves the problems that will be faced when the EV is promoted, and at the same time achieves the purpose of protecting the earth.
