Problems solved by technology

[0003] 1. The technical difficulty of battery production has increased;
[0004] 2. The battery structure is limited and it is not easy to design a shape that matches the car body;
[0005] 3. Since the battery protection circuit cannot be separated from the battery, maintenance is difficult, and maintenance and replacement costs are relatively high;
[0006] 4. The motor drive system cannot know the state of the battery. If it draws too high a current, it will cause damage to the battery, or cause the protection circuit to activate and cut off the power supply. multiplied by mass
[0007] Based on this, it can be seen that since the operation of an electric vehicle is completely dependent on the battery, the power and state of the battery must be strictly monitored, otherwise it is very easy to cause the vehicle to fail to drive due to power exhaustion or battery failure.
[0008] Among the known patents, Patent Application No. 91104439 of Taiwan Province of China "Energy Management System for Electric Vehicles" discloses a technology for monitoring the battery pack of electric vehicles, using the central control system as the control of the entire vehicle The center collects and monitors the usage status of the battery pack, and determines the output power of the motor drive device according to the needs of the rider. Since the central control system can grasp the information of the whole vehicle, it can inform the rider of the system's operating status through the display device In order to enable the rider to fully grasp the driving dynamics; the major defect of the above-mentioned case is that the re-driving mileage is only estimated based on the remaining power and the current driving speed, and the error range is very large. For traditional gasoline vehicles, because Different people have different driving habits, behavior patterns, loads, or road conditions. Under the same amount of fuel, the mileage will be different. Similarly, if the driver is heavy, or carries other heavy objects, or When driving on poor road conditions and many climbing sections, the power consumption will be faster. Moreover, the aging state of the battery will also affect the actual use efficiency of power
[0009] In terms of other inventions in Taiwan Province of China, application number No. 91123987 "Electronic system and related method for battery power management using a charging and discharging detection device in a system module with a battery power memory function", application No. 91114776 "a An expandable battery state monitoring circuit used in a battery management system", application No. 84106099 "Battery Management System" and other cases, all disclose technical means for battery power management, but their management level is still limited to power monitoring , and it is impossible to perform intelligent memory management and accurate judgment on the mileage that can be driven according to driving habits, behavior patterns, load, driving conditions or battery aging.
[0010] As far as U.S. invention patents are concerned, such as Patent No. 6,023,151 "Method and device for enhancing smart battery performance", the said case proposes a method of implementing dynamic discharge voltage endpoint (EODV) in rechargeable batteries and battery packs to enhance smart battery performance According to the method and device, the dynamic EODV can be adjusted according to the environment, operating conditions, temperature, remaining power, battery chemistry, battery size, waveform indication, discharge rate, and / or the number of charge / discharge cycles performed by the battery to provide It is used to increase the execution time of each discharge cycle of the battery / pack, provide an alarm for saving to disk, ensure that there is enough energy for the actual storage to disk operation, and prolong the service life of the battery / pack; the case is mainly for computers The battery of the system is monitored to avoid accidental loss of data during storage due to battery problems. Therefore, the technical content of the case is not applicable to the battery monitoring and management of electric vehicles, and has nothing to do with battery management of electric vehicles.
[0011] Another example is the US Early Publication Patent No. 20050206345 "Power management method for an electronic apparatus", which proposes a power management method for an electronic device powered by a battery. The electronic device mainly refers to a notebook computer, which is equipped with a An operating system supporting a power management specification, the method comprising the steps of inputting a user-defined remaining charge of the battery into the electronic device, and returning the remaining charge of the battery to the operation system, the operating system supports a power management specification capable of knowing the actual remaining capacity of the battery, and enables the actual remaining capacity of the battery to be displayed on a display, when the operating system compares the user-defined The remaining power of the battery and a reference value related to power management specifications, and when it is known that the remaining power of the battery is lower than the reference value, the operating system activates the electronic device to operate in a low power consumption mode; The case report simply detects the power through the computer operating system, and has no other functions other than that. In addition to the power, the monitoring and management of the battery of an electric vehicle must be able to judge the driving distance based on the power. Therefore, the technical content of the case is not Applicable to the monitoring and management of electric vehicle batteries
