It is possible to generate (and/or collect) second battery state information indicating whether the battery is in a recognized or discharged state. For example, the battery monitoring unit 270 receives information indicating the voltage of the vehicle main battery 240 and determines whether the vehicle main battery 240 is in a charged state, a non-charged state, or a discharged state based on the voltage. It is possible to generate first battery state information indicating, and receives information indicating the voltage of the vehicle auxiliary battery 250 and determines whether the vehicle auxiliary battery 250 is in a charged state, a non-charged state, or a discharged state based on the voltage.

When the ignition key of the vehicle 10 is turned off, the battery monitoring unit 270 may start by receiving the ignition key off signal as an interrupt signal. In addition, the battery monitoring unit 270 may detect the charge amount of the vehicle auxiliary battery 250 using a charge amount detector (not shown). In this case, the charge amount detector is a simple charge amount detector that detects the charge amount of the vehicle auxiliary battery 250 , which is a low voltage battery in a general vehicle or electric vehicle, and may include a device that consumes very little standby power.

The battery monitoring unit 270 compares the current charge amount of the vehicle auxiliary battery 250 detected through the charge amount detector with the recommended lower limit of the charge amount recommended by the battery manufacturer to determine the charging time of the vehicle auxiliary battery 250 (and / or decide). For example, it may be assumed that 100 [%] of the life of the vehicle auxiliary battery 250 remains, ignoring the state of health (SOH), which is the life state of the auxiliary vehicle battery 250 . At this time, assuming that the auxiliary vehicle battery 250 has a capacity of 100 [Ah] and the current charge amount is 80 [%], the amount of current that the auxiliary vehicle battery 250 can discharge is a total of 80 [Ah] ] becomes If the minimum recommended charge amount of the auxiliary vehicle battery 250 is 50 [%], when the dischargeable current of the auxiliary vehicle battery 250 becomes 50 [Ah], the vehicle auxiliary battery 250 is not charged There should be little effect on the life of the vehicle auxiliary battery 250 and there will be no abnormality in the vehicle.

Upon receiving the wake-up command, the control unit 210 starts up, and then wakes up the vehicle main battery 240 and/or the power converter.

Here, when the ignition key of the vehicle 10 is turned off, most of the controllers (eg, the control unit 210 or other components of the vehicle battery unit 20 ) enter a sleep mode after a certain period of time to minimize standby power. That is, a hybrid control unit (HCU) of a hybrid and plug-in electric vehicle and/or a vehicle control unit (VCU) of a pure electric vehicle, which is a higher-level controller that can give a charge command to a high voltage battery and a power converter required to charge the auxiliary battery 250 . Unit) also enters sleep mode to minimize standby power.

Accordingly, the controller 210 starts up when the wake-up command is received in a state in which the controller 210 enters a sleep mode. After starting, the vehicle main battery 240 and/or the power converter automatically wake-up. Here, the wake-up of the vehicle main battery 240 refers to the wake-up of a battery management system (BMS).

6 is a flowchart illustrating a system for charging and controlling vehicle batteries according to an embodiment of the present invention.

Referring to FIG. 6 , the method of charging and controlling vehicle batteries according to an embodiment of the present invention may include collecting information indicating the state of charge of the vehicle main battery 240 ( S610 ).

For example, the battery monitoring unit 270 may include first battery state information indicating whether the vehicle main battery 240 is in a charged state, a non-charged state, or a discharged state, and whether the vehicle auxiliary battery 250 is in a charged state or not. It is possible to generate (and/or collect) second battery state information indicating whether the battery is in a non-charged state or a discharged state.

For example, the battery monitoring unit 270 receives information indicating the voltage of the vehicle main battery 240 and determines whether the vehicle main battery 240 is in a charged state, a non-charged state, or a discharged state based on the voltage. It is possible to generate first battery state information indicating, and receives information indicating the voltage of the vehicle auxiliary battery 250 and determines whether the vehicle auxiliary battery 250 is in a charged state, a non-charged state, or a discharged state based on the voltage. It is possible to generate second battery state information indicating whether the To this end, the battery monitoring unit 270 may be connected to a voltage terminal of the vehicle main battery 240 and/or a voltage terminal of the vehicle auxiliary battery 250 .

On the other hand, the charged state may indicate a state in which electrical energy (or power) is being charged by the generator (and/or other power source) of the battery, and the non-charged state is a state in which charging of the corresponding battery is stopped. may represent a state in which electrical energy (or electric power) is being accumulated (accumulation of power).

In addition, the discharged state means a case in which the value of the dark current (and/or leakage current) checked (and/or measured) from the vehicle main battery 240 and/or the vehicle auxiliary battery 250 exceeds a predetermined reference value. can do. In this case, the predetermined reference value may be a value set by the controller 210 or a pre-determined value. On the other hand, the battery monitoring unit 270 is a current (and/or measured) that is checked (and/or measured) from the vehicle main battery 240 and/or the vehicle auxiliary battery 250 in the state that the vehicle 10 is started off (OFF). / or power) alone, the value of the dark current (and/or leakage current) may be measured and compared and analyzed with the predetermined reference value.

In this case, each of the first SoC information and the second SoC information may indicate a state in which the battery is full when the remaining capacity is 100 [%] and a state in which the battery is exhausted when the remaining capacity is 0 [%].

As another example, the battery monitoring unit 270 may generate only the second battery state information indicating whether the auxiliary vehicle battery 250 is in a charged state, a non-charged state, or a discharged state. For example, the battery monitoring unit 270 may generate both the first battery state information and the second battery state information in normal times, but may generate only the second battery state information when a predetermined condition is satisfied.

The reason for considering this condition is that, in the process of charging the vehicle main battery 240 and/or the vehicle auxiliary battery 250 , the vehicle main battery 240 and/or the vehicle auxiliary battery 240 and/or the vehicle auxiliary battery due to a collision or other reasons in the charging process It may occur that the electric energy (and/or power) charged (and/or stored) in the battery 250 is discharged, and this may result in the vehicle 10 as the required electric energy (and/or power) is insufficient. It can be seen that this was taken into account in that there may be situations in which the control of is difficult or impossible. Even if a problem occurs in the vehicle 10, if it is close to a specific location set by the user of the vehicle 10, there is a high probability of receiving help, so there will be few problems, but if it is the opposite, the possibility of a problem will increase will take into account In addition, in the case of the old vehicle 10, it is considered that there is a large risk of a vehicle accident due to a minor problem. Also, considering the SoC value, if a certain amount of electrical energy (and/or power) is charged (and/or stored), even if some discharge occurs, it is not a big problem, and the remaining electrical energy (and/or power) Normal operation of the vehicle 10 is possible, but if the SoC value is low, the vehicle main battery 240 and/or the vehicle auxiliary battery 250 may be completely discharged due to partial discharge, making it difficult for the vehicle 10 to operate normally. This is taken into account that risks may arise.

For example, the predetermined condition means that ① the GPS location information of the vehicle 10 is out of a predetermined distance from a specific location (eg, home, work) set by the user of the vehicle 10, ② the vehicle ( The time difference between the year of 10) and the current time (eg, year difference, month difference, date difference), ③ SoC value indicated by the first SoC information or second SoC information, or the SoC value indicated by the first SoC information and the second 2 It may be determined according to whether a value calculated based on the average of SoC values indicated by the SoC information exceeds a predetermined threshold value.

Also, the method for charging and controlling vehicle batteries according to an embodiment of the present invention may include generating a command to charge the vehicle auxiliary battery according to whether a criterion is satisfied ( S630 ).

For example, the control unit 210 determines whether a predetermined criterion is satisfied based on whether the first battery state information and/or the second battery state information indicates a charging state, a non-charging state, or a discharging state. In some cases, a command for controlling the vehicle main battery 240 and/or the vehicle auxiliary battery 250 to be charged may be generated. In addition, the control unit 210 determines whether the predetermined criterion is not satisfied based on whether the first battery state information and/or the second battery state information indicates a charged state, a non-charged state, or a discharged state. In this case, it is possible to generate a command for controlling the connection between the vehicle main battery 240 and/or the vehicle auxiliary battery 250 and the charging/discharging unit (not shown) (and/or the generator or other power source) to be cut off.

As another example, the controller 210 controls the vehicle main battery 240 only when the first SoC information included in the first battery state information and/or the second SoC information included in the second battery state information satisfies a predetermined criterion. ) and/or a command for controlling the vehicle auxiliary battery 250 to be charged may be generated. In addition, when the first SoC information included in the first battery state information and/or the second SoC information included in the second battery state information does not satisfy the predetermined criteria, the controller 210 controls the vehicle main battery 240 . And/or it is possible to generate a command for controlling the connection between the vehicle auxiliary battery 250 and the charging/discharging unit (not shown) (and/or a generator, other power source) is cut off.

In addition, when the command generated by the control unit 210 indicates a command not to charge the vehicle auxiliary battery 250, the vehicle auxiliary battery 250 has a charging/discharging unit (not shown) (and/or a generator, The power terminal of the vehicle auxiliary battery 250 and/or the charging/discharging unit (not shown) (and/or generator, other power source) may be controlled to disconnect (cut off) the connection with other power sources.

The method according to an embodiment of the present invention may include only some of S610 to S640, and according to another example, the order of S610 to S640 may be changed.
