It can be used in the device.

As shown in FIG. 1, the electric vehicle 1 includes a battery 2 for supplying power to a motor. For example, a hybrid vehicle mounts a battery pack composed of a plurality of battery cells in order to receive necessary power. The plurality of battery cells included in the battery pack needs to equalize the voltage of each battery cell in order to improve safety, lifespan, and high power. The battery control device allows each battery to have an appropriate voltage while charging or discharging the batteries of the battery pack. On the other hand, since a plurality of battery cells are difficult to maintain a stable state due to various factors, such as a change in internal impedance, a battery management system has a balancing function for balancing the state of charge of a plurality of battery cells.

For example, a difference in state of charge (or remaining capacity) between battery cells in a battery pack may occur over time due to the difference in self discharge rate of the battery cells in the battery pack. In order to overcome the capacity imbalance between the battery cells, a separate circuit is configured to charge and / or buck each battery cell.

2 is a view showing the configuration of a hybrid electric vehicle for explaining an embodiment of the present invention. The battery control device and method thereof of the present invention can be applied not only to a hybrid electric vehicle but also to a pure electric vehicle and a general vehicle.

Driven wheels driven by a power source are front-wheel in a front-wheel drive vehicle and rear-wheel in a rear-wheel drive vehicle. However, hereinafter, the all-wheel drive vehicle will be described. Embodiments relating to the rear wheel drive vehicle are apparent from the following description of the front wheel drive vehicle.

The M / G unit 102 is a device that selectively functions as a motor or a generator depending on the driving state, which is apparent to those skilled in the art. Therefore, in the following description, for convenience of understanding, the M / G unit 102 may be used with the same name as a motor or a generator, but all refer to the same component. The engine 101 and the motor 102 of the electric vehicle are connected to a transmission in series.

In addition, the M / G unit 102 is driven by a signal of an inverter 104 under the control of a motor control unit (MCU) (hereinafter referred to as "MCU") 103.

The inverter 104 drives the M / G unit 102 as a power source by using the electric energy stored in the battery 105 under the control of the MCU 103, and the M / G unit 102. In the case of driving by the generator, the battery 105 is charged with electrical energy generated by the M / G unit 102.

Accordingly, the BCU 114 supplies the calculated hydraulic braking force to the wheel brake device 111 of the front wheel 109 through the control of the hydraulic control system 113.

The electric vehicle, a hybrid electric vehicle electronic control unit for implementing an electric vehicle that performs the maximum speed limiting method by communicating with and controlling the BCU (114) and the MCU (103): HEV-ECU, hereinafter referred to as "HEV-ECU" 115.

The regenerative braking force calculated by the BCU 114 is transmitted to the HEV-ECU 115, whereby the HEV-ECU 115 controls the MCU 103 based on the received regenerative braking force. Thus, the MCU 103 drives the M / G unit 102 as a generator so that the regenerative braking force specified from the HEV-ECU 115 is implemented. At this time, electrical energy generated by the M / G unit 102 is stored in the battery 105.

The battery voltage detector 117 detects a current voltage of the battery 105, and the HEV-ECU 115 may limit the maximum speed of the electric vehicle according to a detected deviation of the current voltage and a preset reference voltage. Provide the resulting data.

On the other hand, an electric vehicle uses a battery to drive a motor, and the life of the battery is an important part of the electric vehicle. As the battery ages, the voltage of the battery cell changes slightly. This imbalance is one of the important factors that can reduce the life of the battery. In order to prolong battery life by preventing disproportionation between these cells, most electric vehicles must continuously perform cell balancing. The cell balancing is a method of equalizing a voltage with another cell by discharging a current by connecting a small load to a battery cell having a high voltage.
