Description
본 발명은 자동차의 배터리 및 배터리 관련 기능, 예컨대, AMS(Alternator Management System, 발전제어 시스템), ISG(Idle Stop & Go, 아이들 스톱&고) 등의 성능 보장 기술에 관한 것이다. The present invention relates to a battery and battery-related functions of a vehicle, for example, AMS (Alternator Management System, power generation control system), ISG (Idle Stop & Go, Idle Stop & Go) performance guarantee technology.
일반적으로 전기자동차 또는 하이브리드 자동차는 배터리에 저장된 전기 에너지를 에너지원으로 이용한다. 배터리의 상태에 대한 정보는 운행 안전 및 연비 관리 등에 있어서 매우 중요하다.In general, an electric vehicle or a hybrid vehicle uses electric energy stored in a battery as an energy source. Information on the state of the battery is very important for driving safety and fuel economy management.

IBS는 특정 차종의 엔진 유형에 따른 특정 배터리에 대해서만 개발되기 때문에, 초기 출고된 차량 이외의 배터리로 교체할 경우에 AMS, ISG 등 기능의 성능보장이 되지 않아, 개발시 의도된 연비향상 효과를 기대할 수 없게 된다.Since IBS is developed only for specific batteries according to the engine type of a specific vehicle model, if the battery is replaced with a battery other than the initially shipped vehicle, the performance of functions such as AMS and ISG is not guaranteed. becomes impossible
구체적으로 설명하자면, EMS가 해당 차량의 엔진정보(배기량, 연료형태, 엔진타입 등)를 IBS에 송신하면, IBS는 미리 정해놓은 배터리 정보(즉, 차량마다 개발 완료된 배터리의 정격용량, 열전달 시정수, 및 각종 파라미터가 정해져 있음) 를 참조하여 해당 배터리의 BTM, SOC 등을 계산한다. 그러나 만약 소비자가 배터리 문제로 인하여 기존 장착된 배터리와 다른 사양(용량, 제조사, 배터리 타입 등의 상이함)의 배터리를 장착하게 되면, 다른 OCV맵에 의해 SOC가 정확하지 않은 값으로 초기화된다. 즉, 배터리 성능을 측정하는 데 중요하게 여겨지는 요소인 배터리 충전량(SOC)은 배터리마다 가지고 있는 OCV맵을 통해서 정보를 취득할 수 있는데, 이 정보는 차종마다 개발시에 특화된다. 따라서, 개발시 정해진 배터리와 다른 사양의 배터리를 장착할 경우에는 배터리 센서(IBS)의 OCV맵 정보와 실제 배터리의 OCV맵 정보가 다르므로 정확한 SOC 계산이 불가능하고, 이에 의해 연비절감을 위한 발전제어 시스템(AMS)이나 아이들 스톱&고(ISG) 시스템이 정상적으로 동작하지 못하게 되어 연비절감의 효과를 기대하기 어렵다.Specifically, when the EMS transmits the vehicle's engine information (displacement amount, fuel type, engine type, etc.) to the IBS, the IBS sends predetermined battery information (ie, the rated capacity of the developed battery for each vehicle, heat transfer time constant, etc.) , and various parameters are determined) to calculate the BTM, SOC, etc. of the corresponding battery. However, if a consumer installs a battery with a different specification (different capacity, manufacturer, battery type, etc.) from the previously installed battery due to a battery problem, the SOC is initialized to an incorrect value by a different OCV map. That is, the battery charge amount (SOC), which is an important factor in measuring battery performance, can be acquired through the OCV map of each battery, and this information is specialized for development for each vehicle model. Therefore, when installing a battery with a different specification from the battery specified during development, accurate SOC calculation is impossible because the OCV map information of the battery sensor (IBS) and the OCV map information of the actual battery are different, thereby controlling power generation to reduce fuel consumption As the AMS or Idle Stop & Go (ISG) system does not operate normally, it is difficult to expect the effect of reducing fuel consumption.
만일 이러한 문제를 회피하기 위하여 차종마다 그리고 배터리 종류마다 각각 별도로 개발(R&D) 과정을 거쳐야 한다면 개발비가 과다 발생하게 될 것이다. 즉, 개발이 필요한 배터리마다 차량을 제작하여 온도챔버에 넣고 오랜시간 온도별로 테스트를 각각 진행해야 하며, 1000A 이상의 시뮬레이션이 가능한 충방전기를 이용하여 SOC 테스트를 수행해야 하고, IBS에 대해 차종마다 품번이 별개로 발생되어 관리비용이 발생하게 된다.In order to avoid this problem, if the R&D process for each vehicle model and each battery type has to be performed separately, the development cost will be excessive. That is, for each battery that needs to be developed, a vehicle must be manufactured, put in a temperature chamber, and each temperature is tested for a long time. SOC tests must be performed using a charger and discharger capable of simulating over 1000A. Separately, management costs are incurred.
본 발명의 목적은 상술한 종래 기술의 한계점을 극복하기 위하여 특정 차량에 대해 정해진 배터리 이외의 다른 배터리로 교체되더라도 AMS, ISG 등의 연비절감대책 및 기타 자동차 성능에 영향이 없도록 보장하며, 별도의 배터리 개발시 소요되는 개발비 및 관리비를 절감하는 기술을 제안하고자 하는 것이다.It is an object of the present invention to ensure that fuel efficiency reduction measures such as AMS and ISG and other vehicle performance are not affected even if a battery other than a battery specified for a specific vehicle is replaced in order to overcome the above-described limitations of the prior art, and a separate battery This is to suggest a technology that reduces development and management costs required for development.
상기 목적을 달성하기 위하여, 본 발명의 한 측면에 따르면, 다수의 배터리정보를 취합하여 배터리 데이터베이스(DB)를 구축하고; 사용자가, 차량 개발시 정해진 정격배터리와 다른 사양의 이종배터리로 배터리를 교체한 경우에 이 교체된 이종배터리의 배터리정보를 입력하면 입력된 배터리정보가 EMS에 전송되고; EMS는 수신한 배터리정보를 배터리관련 기능 수행부에 전송하고; 배터리관련 기능 수행부는 수신한 배터리정보로 상기 DB를 참조하여 차량에 적용된 기능을 수행하기 위한 배터리 파라미터를 가져와 상기 기능을 수행하는 것을 포함하는 배터리 독립적 자동차 성능 보장 방법이 제공된다. 본 발명에서 배터리관련 기능 수행부는 IBS와 BMS를 포함하지만, 이들에 한정되는 것은 아니다.In order to achieve the above object, according to an aspect of the present invention, a plurality of battery information is collected to build a battery database (DB); When the user replaces the battery with a different type of battery having a different specification from the rated battery set during vehicle development, when the user inputs battery information of the replaced different type of battery, the inputted battery information is transmitted to the EMS; The EMS transmits the received battery information to the battery-related function execution unit; The battery-related function performing unit refers to the DB with the received battery information to obtain a battery parameter for performing a function applied to the vehicle and performs the function. In the present invention, the battery-related function performing unit includes, but is not limited to, IBS and BMS.
상기 목적을 달성하기 위하여, 본 발명의 다른 측면에 따르면, 다수의 배터리정보 및 배터리 파라미터를 포함하여 구축된 배터리 데이터베이스(DB); 사용자가, 차량 개발시 정해진 정격배터리와 다른 사양의 이종배터리로 배터리를 교체한 경우에 이 교체된 이종배터리의 배터리정보를 입력하도록 사용자에게 제공되는 배터리정보 입력부; 상기 배터리정보 입력부에 입력된 배터리정보가 전송되는 EMS; EMS로부터 상기 배터리정보가 전송되면 이를 수신하여 상기 DB를 참조하여 차량에 적용된 기능을 수행하기 위한 배터리 파라미터를 가져와 상기 기능을 수행하는 배터리관련 기능 수행부를 포함하는 배터리 독립적 자동차 성능 보장 장치가 제공된다.In order to achieve the above object, according to another aspect of the present invention, a battery database (DB) constructed including a plurality of battery information and battery parameters; a battery information input unit provided to the user to input battery information of the replaced different type of battery when the user replaces the battery with a different type of battery having a specification different from the rated battery determined during vehicle development; EMS through which the battery information input to the battery information input unit is transmitted; When the battery information is transmitted from the EMS, a battery-independent vehicle performance assurance device including a battery-related function performing unit that receives the battery information and retrieves battery parameters for performing a function applied to the vehicle by referring to the DB is provided.
본 발명에 따르면, 자동차 개발시 정해진 배터리 이외의 모든 배터리의 호환 사용이 가능해진다. 즉, 초기 개발시의 배터리 이외의 이종배터리에 의해서도 AMS나 ISG 등의 기능이 정상동작 할 수 있게 되고, 오리지널 배터리와 동일한 연비 개선의 효과를 얻을 수 있다. According to the present invention, it is possible to use all batteries other than the batteries specified when developing a vehicle. That is, functions such as AMS and ISG can operate normally even with a different type of battery other than the battery at the time of initial development, and the same effect of improving fuel efficiency as the original battery can be obtained.
또한 차량 개발시에 한 종의 배터리에 대해서만 개발하면 되므로, 차량 샤시다이나모/온도챔버 등의 비용이 절감되어(기준: 중국 샤시다이나모 챔버 사용 기준, 10시간 기준 약 1700만원, 3일(저온, 상온, 고온)) 총 개발비가 절감된다. 실제로, 배터리 1개 제품 개발 비용인 대략 5,400만원의 비용절감의 효과를 얻을 수 있어, 차종당 배터리 3개를 기준으로 한다면 약 1억5천만원의 비용절감이 가능해진다.In addition, since it is necessary to develop only one type of battery during vehicle development, the cost of vehicle chassis dynamo/temperature chamber is reduced (standard: based on the use of Chinese chassis dynamometer chamber, about 17 million won for 10 hours, 3 days (low temperature, room temperature, high temperature)) The total development cost is reduced. In fact, it is possible to obtain the effect of cost reduction of approximately 54 million won, which is the cost of product development for one battery, and it is possible to reduce the cost by about 150 million won if three batteries per vehicle type are the standard.
또한, 현재 PCB가 일원화되어 있기는 하지만, 차종별로 SW(소프트웨어)가 상이하게 되면 P/N(파트넘버)가 다원화되고 관리비용(재고 관리 등)이 증가하게 될 것인데, 본 발명에 따르면 SW가 일원화되어 P/N이 일원화되어 관리비 절감 효과를 얻을 수 있다.In addition, although the current PCB is unified, if SW (software) is different for each vehicle type, P/N (part number) will be diversified and management costs (stock management, etc.) will increase. According to the present invention, SW By unifying, P/N can be unified and management cost savings can be obtained.

도 1은 본 발명의 개념을 설명하기 위한 개략 순서도이다.1 is a schematic flowchart for explaining the concept of the present invention.
차량 개발시 정해져서 등록된 배터리(10)(이하, '정격배터리')의 정보를 참조하여(20) 배터리관련 기능 수행부(30)(본 실시예에서는 IBS로 특정함)가 BTM, SOC 등의 배터리 사양항목을 계산하여, 연비절감을 위한 발전제어 시스템(AMS) 또는 아이들 스톱&고(ISG) 시스템의 정상적 동작을 위한 데이터를 해당 시스템(AMS, ISG 등)에 제공한다. 그런데 차량 출고 후 정격배터리(10)와 다른 사양의 배터리(이하, '이종배터리')로 교체할 경우(40)에는 이 교체된 이종배터리 정보를 사용자(정비자 포함)가 직접 입력하도록 한다(50). 입력된 이종배터리 정보가 IBS(30)로 전송되면 IBS(30)는 새로운(교체된) 이종배터리의 정보를 데이터베이스(60)에서 참조하여 필요한 배터리 사양항목을 계산(30)해서 이종배터리에 상응하여 AMS나 ISG 등의 기능이 수행되도록 필요 데이터를 해당 시스템에 제공한다.With reference to information of the battery 10 (hereinafter, 'rated battery') determined and registered at the time of vehicle development (20), the battery-related function performing unit 30 (specified as IBS in this embodiment) is a BTM, SOC, etc. By calculating the battery specification items, data for the normal operation of the power generation control system (AMS) or the idle stop & go (ISG) system for fuel saving is provided to the relevant system (AMS, ISG, etc.). However, in the case of replacing the rated
이러한 개념의 본 발명을 구현하기 위해서는 기존 양산 및 검증된 다양한 배터리들에 대한 정보를 취합하여 데이터베이스를 구축(DB화)하는 것이 우선적으로 필요하다. DB화 시에는 배터리 특성별로 분류하여 최대한 일관된 성능 확보가 중요하다. 도 1에서와 같이 출고 후 배터리 노후로 인한 교체시 이종배터리로 교체한 사용자가 차량에 이종배터리 정보를 입력하면, 본 발명에 따라 이 입력된 이종배터리 정보를 DB에서 참조하여 AMS와 ISG의 성능 지속을 보장한다.In order to implement the present invention of this concept, it is first necessary to build a database (DB) by collecting information on various batteries that have been mass-produced and verified. In the case of DB, it is important to classify by battery characteristics and secure as much consistent performance as possible. As shown in FIG. 1, when a user who has replaced the battery with a different type of battery during replacement due to the aging of the battery after leaving the factory inputs different battery information into the vehicle, the performance of the AMS and ISG is continued by referring to the inputted different battery information in the DB according to the present invention. to ensure
아래의 표 1은 본 발명에서 구축된 배터리 데이터베이스를 예시한다. 이 예에 따르면 배터리 제조사(업체), 정격용량, 및 기타 필요인자(배터리 모델명 등)를 기준으로 각 배터리의 열전달 시정수, 개방회로전압(OCV), 기타 각종 파라미터를 저장해 데이터베이스를 구축한다. Table 1 below illustrates the battery database constructed in the present invention. According to this example, the database is built by storing the heat transfer time constant, open circuit voltage (OCV), and other various parameters of each battery based on the battery manufacturer (company), rated capacity, and other necessary factors (battery model name, etc.).
반면에 종래의 정격배터리의 경우의 배터리 정보 참조에 관해 설명하면, 차량 개발시에 결정된 배터리 정보가 EMS에 해당 차량정보로서 저장되고(변경 불가) 고정된 엔진정보를 IBS에 전송한다. 따라서, 배터리 변경시 반드시 출고시점과 동일 사양의 배터리(정격배터리) 장착이 필요한 것이다. 그러나 실제로는 소비자가 동일 사양이 아닌 사양의 배터리(이종배터리)를 장착하는 것이 보통이다. 이 경우에 AMS와 ISG 성능이 보장되지 않음은 앞에서 언급하였다. On the other hand, referring to the battery information reference in the case of the conventional rated battery, the battery information determined at the time of vehicle development is stored as the corresponding vehicle information in the EMS (cannot be changed) and the fixed engine information is transmitted to the IBS. Therefore, when changing the battery, it is necessary to install a battery (rated battery) of the same specification as the time of shipment. However, in reality, it is common for consumers to install batteries (different types of batteries) with specifications other than the same specifications. As mentioned above, AMS and ISG performance are not guaranteed in this case.
아래 표 2는 종래의 차종별 EMS에 저장된 배터리 정보의 예시도이다. 동일한 ××차종에 대한 모델별 엔진 크기, 유종, 형태 등에 따른 배터리 정보만이 저장되어 있음을 알 수 있다.Table 2 below is an exemplary diagram of battery information stored in the conventional EMS for each vehicle type. It can be seen that only battery information according to engine size, oil type, shape, etc. for each model of the same X X vehicle is stored.
도 2는 상술한 본 발명의 개념을 구현한 제1실시예의 시스템 구성도이다. 이종배터리로 교체했을 경우에 사용자가 이 배터리의 제조원이나 모델명 등의 배터리 정보를 입력하도록 하기 위하여 계기판 클러스터를 입력 수단으로 구성하는 실시예이다.2 is a system configuration diagram of the first embodiment implementing the concept of the present invention described above. This is an embodiment in which the instrument cluster cluster is configured as an input means in order to allow a user to input battery information such as a manufacturer or model name of the battery when a different type of battery is replaced.
사용자가 차량의 배터리를 정격배터리로 교체하면 아무런 추가 조치 없이 해당 차량의 EMS와 IBS는 등록된 배터리에 대한 정보를 참조하여 설계 사양대로 AMS나 ISG 등의 기능을 수행한다. 그러나 사용자가 배터리를 이종배터리로 교체하면 사용자(정비자 포함)는 계기판 클러스터에 이 이종배터리의 배터리정보(상기 표 1 참조)를 입력해야 한다. 이를 위해, 계기판 클러스터의 기존 USM(user setting mode)에 본 발명의 배터리정보 입력 메뉴를 추가로 구성한다. If the user replaces the vehicle's battery with a rated battery, the EMS and IBS of the vehicle refer to the registered battery information and perform functions such as AMS or ISG according to the design specification without any additional action. However, when the user replaces the battery with a different type of battery, the user (including the mechanic) must input the battery information of the different type of battery (refer to Table 1 above) into the instrument cluster cluster. To this end, the battery information input menu of the present invention is additionally configured in the existing user setting mode (USM) of the instrument cluster cluster.
교체된 이종배터리의 정보 입력을 유도하는 방식은 다양하게 적용할 수 있다. 예를 들어, 1) 차량의 사용설명서 등에 기재하여 사용자가 능동적으로 자기의 책임하에 입력하도록 하는 방식, 2) 고객 편의성 증진, 차량 품질 유지, 및 고객흡인력 제고를 위하여 이종배터리로 교체시 이종배터리의 장착 사실을 감지하여 사용자에게 이 새로운 배터리에 대한 정보를 입력하도록 클러스터에 메뉴를 표시하거나 알람음 등 경고를 발령하도록 차량의 ECU 또는 EMS 또는 전용 컨트롤러를 구성하는 방식, 3) 배터리 교체시점은 차량 모든 전원이 리셋될 때이므로 클러스터 또는 AVN에 예를 들어 “배터리를 교체하셨습니까?”라는 문구와 후속 안내 문구를 표시하여 이종배터리 정보의 입력을 안내하는 방식 등을 적용할 수 있다. A method of inducing information input of the replaced heterogeneous battery can be applied in various ways. For example, 1) a method in which the user can actively input the information under his/her own responsibility by writing in the vehicle's user manual, 2) When replacing a different type of battery with a different type of battery to improve customer convenience, maintain vehicle quality, and improve customer attraction A method of configuring the vehicle's ECU or EMS or dedicated controller to display a menu on the cluster or issue a warning, such as an alarm, to input information about this new battery to the user by detecting the fact that the battery is installed, 3) The time to replace the battery is Since it is when the power is reset, it is possible to apply a method of guiding input of heterogeneous battery information by displaying the phrase “Have you replaced the battery?” and a follow-up guide on the cluster or AVN, for example.
이종배터리로 교체한 사용자가 클러스터에 배터리정보를 입력하면 이 배터리정보는 CAN통신으로 EMS에 전송된다. EMS는 수신한 배터리정보를 LIN통신으로 IBS에 전송하고, IBS는 이 배터리정보로 DB를 참조하여 해당 이종배터리의 열전달 시정수, 개방회로전압(OCV), 또는 기타 필요한 파라미터(BTM, SOC 등)를 가져와 차량에 적용된 AMS나 ISG 등의 기능을 수행하도록 한다. When a user who has replaced a different type of battery inputs battery information into the cluster, this battery information is transmitted to the EMS through CAN communication. The EMS transmits the received battery information to the IBS through LIN communication, and the IBS refers to the DB with this battery information, and the heat transfer time constant, open circuit voltage (OCV), or other necessary parameters (BTM, SOC, etc.) to perform functions such as AMS or ISG applied to the vehicle.
도 3은 본 발명의 개념을 구현한 제2실시예의 시스템 구성도이다. 이종배터리로 교체했을 경우에 사용자가 이 배터리의 정보를 입력하도록 하기 위하여 진단통신 장치를 입력 수단으로 구성하는 실시예이다.3 is a system configuration diagram of a second embodiment embodying the concept of the present invention. This is an embodiment in which a diagnostic communication device is configured as an input means in order to allow a user to input information on the battery when a different type of battery is replaced.
이 실시예의 경우에도 앞서 설명한 클러스터의 경우와 유사하게, 사용자가 스스로 진단통신 장치를 연결하여 새로운 배터리정보를 입력하도록 할 수도 있고, 사용자에게 새로운 배터리정보를 입력할 것을 알리기 위하여 진단통신 장치에 메뉴를 표시하거나 알람음 등 경고를 발령할 수 있다(경고가 반드시 진단통신 장치에서 발생될 필요는 없음). 물론, 진단통신 장치에는 그 기능 항목에 본 발명의 배터리정보 입력 기능이 추가되어야 할 것이다.In the case of this embodiment, similarly to the case of the cluster described above, the user may connect the diagnostic communication device by himself/herself to input new battery information, or a menu may be displayed on the diagnostic communication device to notify the user to input new battery information. It can display or issue a warning such as an alarm sound (a warning does not necessarily have to be generated by the diagnostic communication device). Of course, in the diagnostic communication device, the battery information input function of the present invention should be added to the function item.
이종배터리로 교체한 사용자(이 경우에는 주로 정비자가 될 것임)가 진단통신 장치에 배터리정보를 입력하면 이 배터리정보가 CAN통신으로 EMS에 전송되고 이어서 LIN통신으로 IBS에 전송되어 해당 차량에 적용된 AMS나 ISG 등의 기능을 수행하도록 하는 것은 앞에서 설명한 것과 같다.When a user who has replaced a different type of battery (in this case, he will be a mechanic) inputs battery information into the diagnostic communication device, this battery information is transmitted to EMS through CAN communication and then to IBS through LIN communication to AMS applied to the vehicle. To perform functions such as ISG or ISG is the same as described above.
도 4는 본 발명의 개념을 구현한 제3실시예의 시스템 구성도이다. 정격배터리를 이종배터리로 교체했을 경우에 LIN 통신의 진단통신 장치를 이용하여 배터리 정보를 IBS에 직접 입력한다. 이 실시예는 사실상 IBS에 접근 가능한 개발자가 이종배터리 정보를 입력하는 경우의 실시예이다.4 is a system configuration diagram of a third embodiment embodying the concept of the present invention. When the rated battery is replaced with a different type of battery, the battery information is directly input into the IBS using the diagnostic communication device of LIN communication. This embodiment is an embodiment in which a developer who has access to the IBS actually inputs information about different types of batteries.
도 5는 이종배터리로 교체 후의 사용자 입력을 유도하기 위한 프로세스 예시도이다.5 is a diagram illustrating a process for inducing a user input after replacement with a different type of battery.
앞에서 언급한 바 사용자가 정격배터리로 교체했는지 이종배터리로 교체했는지 판단하여 스스로 배터리정보를 입력하게 하는 것은 불합리할 수 있다. 따라서 도 5와 같은 흐름으로 배터리 교체 후 프로세스가 진행되도록 설계하는 것이 바람직할 수 있다. 도 6에 나타낸 프로세스는 하나의 예시형태로, 실제로는 본 발명의 기본 개념의 구현을 위한 다양하고 구체적인 프로세스를 만들 수 있을 것이다.As mentioned above, it may be unreasonable for the user to input battery information by himself/herself by determining whether the user has replaced the rated battery or a different type of battery. Therefore, it may be desirable to design the process to proceed after replacing the battery in the same flow as in FIG. 5 . The process shown in FIG. 6 is an exemplary form, and in practice, various and specific processes for implementing the basic concept of the present invention may be made.
먼저, 차량(예를 들어, ECU, EMS 등)이 배터리 교체 사실을 인식하고(110), 교체된 배터리가 정격배터리인지 이종배터리인지 판단한다(120). 정격배터리로 교체되었다면 통상의 IBS 동작을 수행한다(170). First, the vehicle (eg, ECU, EMS, etc.) recognizes the fact that the battery has been replaced ( 110 ), and determines whether the replaced battery is a rated battery or a different type of battery ( 120 ). If the rated battery has been replaced, the normal IBS operation is performed (170).
만일 교체된 배터리가 이종배터리라면 사용자에게 이 교체된 배터리의 정보를 입력하라는 형식의 경고를 발령한다(130). 그리고 배터리정보 입력 메뉴를 클러스터나 진단통신 장치에 표시한다(140). 배터리정보의 입력이 완료되었는지 판단하여(150) 완료되지 않았으면 계속 경고를 해서 사용자가 배터리정보를 입력하도록 하고, 완료되었으면 앞에서 설명한 것과 같이 새로운 배터리정보로 DB를 참조하여 새로운 파라미터를 이용해서 IBS 동작을 수행한다(160).If the replaced battery is a different type of battery, a warning in the form of inputting information about the replaced battery to the user is issued ( 130 ). Then, the battery information input menu is displayed on the cluster or the diagnostic communication device (140). It is determined whether the input of battery information has been completed (150), and if it is not completed, a warning is continuously given so that the user can input the battery information, and when it is completed, the IBS operation is performed using new parameters by referring to the DB with new battery information as described above. to perform (160).
이상, 본 발명의 바람직한 실시예를 통하여 본 발명의 구성을 상세히 설명하였으나, 본 발명이 속하는 기술분야의 통상의 지식을 가진 자는 본 발명이 그 기술적 사상이나 필수적인 특징을 변경하지 않고서 본 명세서에 개시된 내용과는 다른 구체적인 형태로 실시될 수 있다는 것을 이해할 수 있을 것이다. 이상에서 기술한 실시예들은 모든 면에서 예시적인 것이며 한정적이 아닌 것으로 이해해야만 한다. 예를 들어, 배터리정보 입력 기능을, 배터리 DB 자체를 서버에서 OTA 방식으로 IBS에 보내는 방식으로 구현할 수 있다. 이러한 방식이 가능한 이유는 다음과 같다. 최초 개발된 IBS 내의 배터리 DB는 한정된 정보인데, 만일 추가 DB가 필요한 경우에는 DB 서버를 구축하고 개발자는 DB 서버를 관리하여 추가 배터리 DB를 업데이트 할 수 있다. 이 경우에 전세계 모든 IBS는 OTA를 통해 업데이트될 수 있다. 이러한 방식으로 본 발명을 구현하면 신규 배터리에 대한 성능까지 보장이 가능해지는 추가적인 이득을 얻을 수 있다. As mentioned above, although the configuration of the present invention has been described in detail through preferred embodiments of the present invention, those of ordinary skill in the art to which the present invention pertains will appreciate that the present invention is disclosed in the present specification without changing its technical spirit or essential features. It will be understood that the present invention may be implemented in a specific form other than the above. It should be understood that the embodiments described above are illustrative in all respects and not restrictive. For example, the battery information input function can be implemented by sending the battery DB itself to the IBS in an OTA method from the server. The reason why this method is possible is as follows. The battery DB in the initially developed IBS is limited information. If an additional DB is needed, a DB server is built and the developer can update the additional battery DB by managing the DB server. In this case, all IBSs in the world can be updated via OTA. If the present invention is implemented in this way, it is possible to obtain an additional benefit of guaranteeing the performance of a new battery.
