전기자동차 배터리 충전 방법{Electric car battery charging method} Electric car battery charging method

본 발명은 전기자동차의 충전 속도를 높이기 위한 방법, 충전구를 복수로 하거나 배터리를 분할해서 충전 또는 이들의 조합을 통하여 전기자동차의 충전 속도를 높이는 방법에 관한 것이다. 본 발명은 전기자동차의 충전 속도를 높이기 위한 방법, 충전구를 복수로 하거나 배터리를 분할해서 충전 또는 이들의 조합을 통하여 전기자동차의 충전 속도를 높이는 방법에 관한 것이다.The present invention relates to a method for increasing the charging speed of an electric vehicle, a method of increasing the charging speed of the electric vehicle through charging or a combination of a plurality of charging ports or dividing the battery. The present invention relates to a method for increasing the charging speed of an electric vehicle, a method of increasing the charging speed of the electric vehicle through charging or a combination of a plurality of charging ports or dividing the battery.

전기자동차의 충전 속도는 전기자동차의 이용에 큰 비중을 차지한다.        The charging speed of an electric vehicle accounts for a large portion of the use of the electric vehicle.

도 1에서 보는 바와 같이 전기자동차의 충전 시스템은 충전기(101), 충전구(102), BMS(103), 배터리(104)로 구분할 수 있다. 현재는 전기자동차의 충전구(102)가 1구만 설치되어 있고 이를 통해 전기를 충전한다. As shown in FIG. 1, the charging system of the electric vehicle may be divided into a charger 101, a charging port 102, a BMS 103, and a battery 104. Currently, only one charging port 102 of the electric vehicle is installed and charges electricity through it.

충전기(101)에 연결된 케이블을 자동차 충전구(102)에 삽입하면 전기가 배터리(104)에 충전되기 시작하고 BMS(103)는 이를 제어한다.When the cable connected to the charger 101 is inserted into the vehicle charging port 102, electricity starts to be charged to the battery 104 and the BMS 103 controls it.

이때 배터리(104)의 충전 시간은 충전 전력과 배터리(104)의 용량에 관계가 있다.At this time, the charging time of the battery 104 is related to the charging power and the capacity of the battery 104.

본 발명은 전기자동차의 충전 속도를 빠르게 하기 위한 방법으로서 충전구를 복수로 하고 복수의 충전기를 통해서도 전기를 충전하도록 하여 충전 속도를 빠르게 하는 방법을 제공하는데 목적이 있다.An object of the present invention is to provide a method of increasing the charging speed by making a plurality of charging ports and charging electricity through a plurality of chargers as a method for increasing the charging speed of an electric vehicle.

본 발명은 전기자동차의 충전 속도를 빠르게 하기 위한 방법에 관한 것으로서, 2곳 이상의 충전기를 통해 전기를 충전하도록 충전구를 복수개 설치하고 배터리를 분할해서 충전할 수 있도록도 함으로서 충전효율을 높인 것을 특징으로 한다. The present invention relates to a method for increasing the charging speed of an electric vehicle, and it is characterized in that charging efficiency is increased by installing a plurality of charging ports to charge electricity through two or more chargers and allowing the battery to be divided and charged. do.

본 발명은 전기자동차의 충전시 충전 속도를 빠르게 할 수 있는 효과를 기대할 수 있다.The present invention can be expected to have the effect of increasing the charging speed when charging the electric vehicle.

도 2는 본 발명이 적용된 전기자동차 충전 개념도
도 3은 도 2에서 배터리의 분할 충전을 도시한 개념도1 is a conceptual diagram of a conventional electric vehicle charging
2 is a conceptual diagram of electric vehicle charging to which the present invention is applied.
FIG. 3 is a conceptual diagram showing the partial charging of the battery in FIG. 2;

도 2는 본 발명에 따른 전기자동차의 충전 시스템을 설명한 것으로 충전구(2)가 2개가 설치되어 있다. 보통의 경우는 1개의 충전구(2)만 이용하고, 여분의 충전기(1)가 있거나 급한 충전이 필요할 경우 2곳의 충전기(1)에서 각각의 충전구(2)에 케이블을 삽입하여 전기를 충전할 수 있다. 이때 BMS(3)에서 전기를 컨트롤 하여 배터리(4)의 충전을 제어한다. 배터리(4)의 용량이 크고 충전기(1)가 여러개 있을 경우는 복수개의 충전기(1)를 이용하여 배터리(4)를 충전할 수 있다.       2 illustrates the charging system of the electric vehicle according to the present invention, and two charging ports 2 are installed. Normally, only one charging port (2) is used, and if there is an extra charger (1) or urgent charging is required, electricity can be supplied by inserting cables into each charging port (2) from two chargers (1). It can be charged. At this time, the BMS 3 controls electricity to control the charging of the battery 4. When the capacity of the battery 4 is large and there are multiple chargers 1, the battery 4 may be charged using the plurality of chargers 1.

도 3은 도 2에서 같이 양쪽에서 충전되는 전기를 제어할 필요가 있을 경우 배터리(4a,4b)를 분할해서 충전하도록 한 것이다. 이때는 하나의 충전기(1)에서 하나의 배터리(4a), 또 하나의 충전기(1)에서 분할 된 다른 하나의 배터리(4b)에 충전를 하는 것과 같은 형태이다.FIG. 3 shows that the batteries 4a and 4b are divided and charged when it is necessary to control electricity charged from both sides as in FIG. 2. In this case, it is the same type as charging one battery 4a in one charger 1 and another battery 4b divided in another charger 1.

즉, 필요에 따라서 설치된 배터리(4)를 통으로 충전하거나, 분할해서 충전하거나 할 수 있다. 회로 구성을 제어함으로서 가능하다. 물론 복수개의 충전기(1)를 연결할 경우는 복수개로 배터리(4)를 분할할 수도 있다.That is, if necessary, the installed battery 4 can be charged with a barrel, or divided and charged. It is possible by controlling the circuit configuration. Of course, when a plurality of chargers 1 are connected, the battery 4 may be divided into a plurality.

이렇게 구성된 충전 시스템에서 대형트럭과 같은 대용량의 배터리(4,4a,4b)를 가진 차량의 경우에는 더욱 큰 효과를 볼 수 있고, 급한 충전이 필요한 경우에도 유익하다.In the charging system configured as described above, in the case of a vehicle having a large capacity battery 4, 4a, 4b such as a large truck, a larger effect can be seen, and it is also advantageous when an urgent charging is required.

여기서 전기자동차라 함은 전기동력을 이용하는 장치까지 포함하여 기존의 내연기관을 대체하는 것을 포함한다. 이와 같은 것은 선박, 드론 등을 포함한다. Here, the electric vehicle includes replacing an existing internal combustion engine including a device using electric power. These include ships, drones, and the like.
