Description

배터리 교체주기가 표시되는 리튬 전지팩 구조{structure of lithium battery pack displaying battery's replacement time}Structure of lithium battery pack displaying battery's replacement time

본 발명은 배터리 교체주기가 표시되는 리튬 전지팩 구조에 관한 것으로, 리튬전지팩 내에 배터리 팩과 PCM 또는 BMS를 격벽을 통해 구분되어 실장하여 구동로직를 통해 전지와 연결된 차량 등의 외부케이블 분리시 sleep 상태로 판단하여 배터리를 사용하지 않을 경우 도통되지 않도록 동작함으로써 장기간 보관시 자가 방전에 의한 완전방전으로 재충전의 문제를 해결할 수 있는 배터리 교체주기가 표시되는 리튬 전지팩 구조에 관한 것이다.The present invention relates to a structure of a lithium battery pack in which the battery replacement cycle is displayed, and a battery pack and a PCM or BMS are separated and mounted in a lithium battery pack through a partition wall, and a sleep state when an external cable such as a vehicle connected to the battery is disconnected through a driving logic. It is determined that the battery does not conduct when the battery is not used, and thus the structure of a lithium battery pack displays a battery replacement cycle capable of solving the problem of recharging through complete discharge by self-discharge during long-term storage.

또한, 본 발명은 배터리 보호회로(PCM) 또는 배터리 관리 시스템에서 발생하은 열을 외부로 방출할 수 있도록 외부 방열핀이 구비된 배터리 케이스 내에 다수의 리튬 전지를 리튬 전지팩으로 구비하여 정전 또는 천재지변 시에도 일정시간 전류를 공급하여 구동이 가능하고, 장기 보관에 따라 배터리의 자가 방전을 방지하고 사용시 배터리의 노후 정도를 표시되도록 하여 비상시에도 배터리의 성능을 발휘하도록 배터리의 교체주기를 표시할 수 있는 배터리 교체주기가 표시되는 리튬 전지팩 구조에 관한 것이다.In addition, the present invention is provided with a plurality of lithium batteries as a lithium battery pack in a battery case equipped with an external heat dissipation fin so that heat generated from a battery protection circuit (PCM) or a battery management system can be discharged to the outside, even in the event of a power failure or natural disaster. Battery replacement that can be driven by supplying current for a certain period of time, prevents self-discharge of the battery due to long-term storage, and displays the battery's aging level when in use, so that the battery's performance can be displayed even in an emergency. It relates to a lithium battery pack structure in which the cycle is displayed.

일반적으로, 차량 연료로는 경유, 휘발유 등의 석유나 LNG, LPG 등의 천연가스와 같은 화석연료가 주로 사용되고 있다.In general, as vehicle fuel, fossil fuels such as petroleum such as diesel and gasoline or natural gas such as LNG and LPG are mainly used.

근래에 들어서는 화석연료를 사용하면 환경을 오염시키는 배기가스가 다량으로 배출되는 문제 등으로 인하여 화석연료 차량의 대안으로서 전기를 에너지원으로 하는 전기차(electric vehicle, EV)가 주목을 받고 있다.In recent years, electric vehicles (EVs) using electricity as an energy source are attracting attention as an alternative to fossil fuel vehicles due to the problem that large amounts of exhaust gas polluting the environment are emitted when fossil fuels are used.

친환경 기술에 대한 관심이 부상함에 따라 하이브리드 자동차, 전기 자동차 등의 사용도 점차 보편화되는 추세이다. 일반적으로 이러한 차종에는 반복해서 충전하여 사용할 수 있는 배터리가 사용된다. As interest in eco-friendly technology emerges, the use of hybrid vehicles and electric vehicles is also becoming more common. In general, batteries that can be repeatedly charged and used are used in these vehicle models.

배터리는 여러 번 충전과 방전을 반복하며 장기간 재사용할 수 있으나, 현재 기술로 배터리의 수명은 한정적이기 때문에 영구적으로 사용할 수 없고 적절한 시기에 배터리를 교체해주는 것이 필요하다. 배터리를 적절한 시기에 새것으로 교체해주지 않으면, 차량의 성능이 저하되고 부품이 망가질 수 있다. 그러나 일반적인 차량 사용자는 배터리의 교체시기가 언제가 적절한지 알기 힘들다는 문제점이 있다. The battery can be reused for a long time by repeating charging and discharging several times, but the current technology has a limited life span, so it cannot be used permanently, and it is necessary to replace the battery at an appropriate time. If the battery is not replaced with a new one at the right time, the vehicle's performance may deteriorate and parts may be damaged. However, there is a problem in that it is difficult for a general vehicle user to know when the battery replacement timing is appropriate.

전기 차량에 사용되는 배터리는 전지팩으로 구성하여 사용되는데, 즉, 리튬전지팩 케이스는 외부환경을 극복할 수 있도록 방수 및 방열, 고강도, 저비용 케이스 제작 기술을 필요로 한다. A battery used in an electric vehicle is composed of a battery pack, that is, a lithium battery pack case requires waterproof and heat dissipation, high strength, and low cost case manufacturing technology to overcome the external environment.

리튬배터리 특성상 배터리의 충,방전 제어를 위한 PCM 혹은 BMS 회로가 반드시 구비되어야 하며, 이로인해 배터리를 사용을 하지 않는 경우에도 PCM이나 BMS동작을 위해 전류를 사용하므로 장기간 보관시 자가 방전에 의한 완전 방전으로 다시 충전을 해야 하는 불편함과 충전에 따른 어려움이 발생된다.Due to the characteristics of lithium batteries, a PCM or BMS circuit must be provided for controlling the charging and discharging of the battery. For this reason, even when the battery is not used, current is used for PCM or BMS operation. Inconvenience of recharging and difficulties associated with charging occur.

또한, 배터리를 비상전원으로 사용하는 경우 장기 운용에 따른 배터리 노후화를 배터리 외부에서 육안으로 확인할 수 있는 방법이 없으면 배터리 노후화로 인해 저장 용량이 저하되어 비상시 충분한 비상전원 공급에 문제가 발생할 수 있다.In addition, when the battery is used as an emergency power source, if there is no way to visually check the aging of the battery due to long-term operation from the outside of the battery, the storage capacity decreases due to the aging of the battery, which may cause problems in supplying sufficient emergency power in an emergency.

따라서, 배터리팩의 수명 측면에서도 정확한 용량을 사용하고 온도 및 기타 환경조건을 고려하여 배터리팩은 사용 조건 및 제어에 수명이 결정되고 이에 따른 배터리의 용량 및 온도 등이 있으며 이는 중요한 요인이 되는 것이다.Accordingly, in terms of the life of the battery pack, the correct capacity is used and the life of the battery pack is determined in terms of use and control in consideration of temperature and other environmental conditions, and accordingly, the capacity and temperature of the battery are important factors.

이에 본 발명은 배터리 교체주기가 표시되는 리튬 전지팩 구조 및 이를 이용한 배터리 교체주기 표시방법을 제안하고자 한다.Accordingly, the present invention is to propose a structure of a lithium battery pack in which the battery replacement cycle is displayed and a method of displaying the battery replacement cycle using the same.

상기 외부장치(60)는 상기 케이스(10, 20)의 컨넥터 체결홈(26)을 통해 삽입된 컨넥터(25)와 배터리 팩(40)이 연결을 통해 인가되는 전원을 전기차 구동에 필요한 전원으로 사용한다.The external device 60 uses the power applied through the connection between the connector 25 and the battery pack 40 inserted through the connector fastening groove 26 of the cases 10 and 20 as power required for driving the electric vehicle. do.

한편, 상기 컨넥터(250)의 결선 구조는 6핀(+), 6핀(-)의 구성된다.Meanwhile, the connection structure of the connector 250 is composed of 6 pins (+) and 6 pins (-).

상기와 같이 상기 배터리 케이스(10, 20) 내의 분리된 배터리 팩과 PCM 또는 BMS 회로기판을 구동하여 배터리 팩의 상태를 확인하여 교체 주기를 진단 및 표시하는 구동로직(50)의 동작을 첨부된 도 7에 도시된 회로도를 기초로 그 동작을 살펴보면, 구동로직(50)은 배터리 팩(40)과 연결된 외부장치(60)의 전기차의 외부케이블이 케이블 컨넥터(25)와 분리되어 배터리 팩(40) 자체만 있을 경우 sleep 상태로 판단하여 배터리 팩(40)의 전원이 사용되지 않도록 절연되도록 동작하고, 외부 케이블이 케이블 컨넥터(25)의 핀 중의 어느 하나가 (+)전원과 short 되어 있어서 케이블이 연결될 때 배터리 팩(40)의 전원이 PCM의 입력전원으로 인가된다.As described above, the operation of the driving logic 50 for diagnosing and displaying the replacement cycle by driving the separated battery pack and the PCM or BMS circuit board in the battery cases 10 and 20 to check the state of the battery pack. Looking at the operation based on the circuit diagram shown in 7, the driving logic 50 is the battery pack 40 by separating the external cable of the electric vehicle of the external device 60 connected to the battery pack 40 from the cable connector 25 If there is only itself, it is determined as a sleep state and operates so that the power of the battery pack 40 is not used, and the external cable is connected to the (+) power because any one of the pins of the cable connector 25 is short. At this time, the power of the battery pack 40 is applied as the input power of the PCM.

즉, 구동로직(50)은 상기 케이블 컨넥터(25)의 핀 중의 어느 하나가 (+)전원과 연결될 때 U4는 +48V DC를 +5V DC로 변환하는 IC로서 5번 핀은 이 IC를 Enable/Disable시키는 핀으로 동작하고, high입력일 때는 Disable, low(GND) 입력일 때에는 Enable된다. 이때 SW1_ON과 BAT_L을 외부 케이블 반대편에서 short(연결)시키면 Enable이 되어 전원이 인가되게 된다.That is, the driving logic 50 is an IC that converts +48V DC to +5V DC when any one of the pins of the cable connector 25 is connected to the (+) power, and pin 5 enables this IC. It operates as a disable pin, and it is disabled when it is a high input, and enabled when it is a low (GND) input. At this time, if SW1_ON and BAT_L are short (connected) from the other side of the external cable, it becomes Enable and power is applied.

따라서, 외부 케이블이 연결되면 배터리 PCM에 전원이 인가되며, 외부케이블이 분리되면 배터리 Sleep 상태로 동작되게 된다.Therefore, when the external cable is connected, power is applied to the battery PCM, and when the external cable is disconnected, the battery is operated in a sleep state.
