[0034] The exemplary embodiments of the present application will be described in more detail below in conjunction with the accompanying drawings in the embodiments of the present application. Although the exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present application and to enable the scope of the present application to be fully conveyed to those skilled in the art.

[0035] In the related technology, a power isolator is generally used to isolate the battery from the vehicle power supply. When the vehicle starts, the starter is powered by the battery, and the vehicle electrical appliances are powered by the DC converter. The starting voltage drop will not affect the vehicle electrical appliances. However, the power isolator and the battery are independent components, which are easily damaged during the supply and production assembly process, increasing the component cost and management cost.

[0036] In view of this, the present embodiment provides a battery, a battery control system and a vehicle to solve the above problems.

[0037] Reference Figure 1 , Figure 1 is a functional module diagram of a battery provided in an embodiment of the present application, from Figure 1 It can be seen that the battery 100 includes: a first electrode plate 101, a first pole 102, a second pole 103, a switch unit 104 and a main control chip 105; wherein the first electrode plate 101 is connected in series between the first pole 102 and the second pole 103, the switch unit 104 is connected in series between the first pole 102 and the first electrode plate 101, and is connected to the main control chip 105; the main control chip 105 is used to output a first electrical signal to the switch unit 104; the switch unit 104 is used to cut off the connection between the first pole 102 and the first electrode plate 101 in response to the first electrical signal.

[0038] In this embodiment, the first electrode plate 101 is a basic component of the battery 100, which is used to receive the charged electric energy and release the electric energy to the outside, and is responsible for the positive electrode reaction of the battery 100. If the battery 100 in this embodiment is a lead-acid battery, then the first electrode plate 101 is lead dioxide. The first pole 102 and the second pole 103 are both interfaces or components for connecting the first pole plate 101 with an external conductor. The switch unit 104 is a switch device controlled by the main control chip 105 or can realize the switch on or off the switch circuit. The switch unit 104 is specifically used to be controlled by the first electrical signal output by the main control chip 105 to cut off the connection between the first pole 102 and the first plate 101. The switch unit 104 is usually in a closed state, that is, the first pole 102 and the first plate 101 are turned on. The first pole 101 is connected in series between the first pole 102 and the second pole 103, and the first pole 102 is generally connected to the DC converter 200 and the vehicle electrical appliance at the end away from the first pole 101. The vehicle electrical appliance is a device such as an instrument and a multimedia system on the vehicle. The DC converter 200 is also connected to the power battery 300, which is the vehicle power supply of the vehicle. The vehicle power supply is stepped down by the DC converter to supply power to the vehicle electrical appliance. However, before the vehicle power supply supplies power to the vehicle electrical appliance, the first pole 102 of the battery 100 is required to supply power to the DC converter 200, and then the DC converter 200 will conduct the connection between the vehicle power supply and the vehicle electrical appliance, so that the vehicle power supply supplies power to the vehicle electrical appliance. In this embodiment, the main control chip can be an intelligent battery monitoring IC with a model number of MM9Z1_638.

[0039] Therefore, when the starter 400 is started normally, a large amount of current will be consumed in a short time. Since the first pole 102 is not disconnected from the first pole plate 101, the starter 400 consumes the power of the external power supply in addition to the power in the battery 100, thereby lowering the voltage output by the external power supply to the vehicle electrical system, causing the voltage output by the external power supply to the vehicle to drop too much, thereby interfering with the normal use of the vehicle electrical system.

[0040] Therefore, when the starter 400 is started, the vehicle can detect whether the starter 400 is started. At this time, the vehicle can inform the main control chip 105 through a CAN (Controller Area Network) signal or a LIN (Local Interconnect Network) signal. If the starter 400 is starting, the main control chip 105 can send a first electrical signal to the switch unit 104 after obtaining the starter start signal. The first electrical signal can be a high-level signal, a low-level signal, or a digital signal. This embodiment is not limited. As long as the first electrical signal is output to the switch unit 104, the switch unit 104 can be converted from an on state to an off state. Then, the switch unit 104 can respond to the first electrical signal, thereby cutting off the connection between the first pole 102 and the first pole plate 101, thereby preventing the starter 400 from pulling down the voltage of the vehicle electrical appliance during the startup process, thereby affecting the normal use of the vehicle electrical appliance.

[0041] A battery 100 provided by an embodiment of the present application includes: a first plate 101, a first pole 102, a second pole 103, a switch unit 104 and a main control chip 105; wherein the first plate 101 is connected in series between the first pole 102 and the second pole 103, since the switch unit 104 is connected in series between the first pole 102 and the first plate 101, and is connected to the main control chip 105; and the main control chip 105 is used to output a first electrical signal to the switch unit 104; and the switch unit 104 is used to respond to the first electrical signal and cut off the connection between the first pole 102 and the first plate 101. Therefore, during the process of frequent starting and stopping of the starter 400 of the vehicle, the first electrical signal can be output to the switch unit 104 through the main control chip 105, and then the switch unit 104 responds to the first electrical signal to cut off the connection between the first pole 102 and the first plate 101, thereby avoiding excessive voltage drop during the starter 400 startup process to interfere with the normal use of the instrument and multimedia system.

[0042] In one embodiment, the main control chip 105 is further used to output a second electrical signal to the switch unit 104 ; the switch unit 104 is further used to respond to the second electrical signal and restore the connection between the first pole 102 and the first plate 101 .

[0043] In this embodiment, the main control chip 105 is also used to output a second electrical signal to the switch unit 104. The second electrical signal is an electrical signal different from the first electrical signal. The difference lies in that the second electrical signal acts on the switch unit 104 and the first electrical signal acts on the switch unit 104, so that the switch unit 104 performs different actions. Specifically, when the starter 400 is started, there is no need to consume a large amount of electrical energy in the battery 100. At this time, the main control chip 105 can also let the whole vehicle know that the starter 400 has been started. At this time, a second electrical signal will be sent out to the switch unit 104. The switch unit 104 responds to the second electrical signal to restore the connection between the first pole 102 and the first pole plate 101.

[0044] In one embodiment, the battery 100 further includes: a second electrode plate 106 and a third electrode column 107; wherein the third electrode column 107 is connected in series between the second electrode plate 106 and the ground terminal.

[0045] In this embodiment, the battery 100 also includes: a second electrode plate 106 and a third electrode column 107. The second electrode plate 106 is mainly responsible for the negative electrode reaction of the battery 100. The third electrode column 107 is an interface or component connecting the second electrode plate 106 with an external conductor. The third electrode column 107 is connected to the ground terminal.

[0046] In this embodiment, the second pole 103 and the third pole 107 are connected to the main control chip 105 respectively.

[0047] In this embodiment, since the main control chip 105 generally does not carry a power supply and the main control chip 105 also needs power, the second pole 103 and the third pole 107 are respectively connected to the main control chip 105 to provide power for the main control chip 105.

[0048] In one embodiment, the battery 100 also includes: a current monitoring chip; wherein the current monitoring chip is arranged on the second electrode plate 106 and connected to the main control chip 105; the current monitoring chip 108 is used to monitor the current of the battery 100 and upload the current to the main control chip 105; the main control chip 105 is also used to respond to the current, obtain the power of the battery 100, and upload the power to the whole vehicle.

[0049] In this embodiment, the battery 100 further includes a current monitoring chip 108 . If the battery 100 is a lead-acid battery, the monitoring chip is disposed on the second electrode plate 106 and connected to the main control chip 105 . The current monitoring chip 108 can monitor the current of the battery 100 on the second electrode plate 106 in real time. The current is the current of the battery 100 currently discharging to the outside or the current of the battery 100 currently charging, and upload the current to the main control chip 105. Since the main control chip 105 is connected to the second pole 103 and the third pole 107, the voltage of the battery 100 can be known accordingly. Then, through the current and voltage of the battery 100, the current power of the battery 100 can be known. Then, the battery 100 uploads the power to the whole vehicle. When the whole vehicle knows that the power of the battery is too low, the whole vehicle can control the power battery to output a larger current or voltage to the circuit connected to the battery through the DC converter to charge the battery. The whole vehicle is the central control unit of the vehicle, and its function is to cooperate with the energy management system of the vehicle-mounted power module of the vehicle to generate power feedback so that the battery can be reversely charged. In this embodiment, the current monitoring chip 108 can be a single-chip sensor IC with the model MLX91208.

[0050] In one embodiment, the switch unit 104 is a MOS tube or a thyristor.

[0051] In this embodiment, the switch unit 104 can be a MOS (Metal-Oxide-Semiconductor Field-Effect Transistor) tube or a thyristor. Taking the switch unit 104 as an N-type MOS tube as an example, the gate of the MOS tube is connected to the main control chip 105, the source is connected to the first electrode plate 101, and the drain is connected to the first electrode 102. Then, when the main control chip 105 outputs a low-level signal, the MOS tube is disconnected, and when the main control chip 105 outputs a high-level signal, the MOS tube is closed. This embodiment does not limit the type of MOS tube corresponding to the switch unit and the type of thyristor, as long as it is ensured that when the first electrical signal is output to the switch unit 104, the switch unit 104 is disconnected, and when the second electrical signal is output to the switch unit 104, the switch unit 104 is closed.

[0052] For example, the following will refer to Figure 3-Figure 6 , and combined Figure 2 The application of the battery 100 provided in this embodiment in a vehicle is described in detail:

[0053] in, Figure 3-Figure 5 The positive plate corresponds to Figure 2 The first electrode plate 101 and the negative electrode plate correspond to Figure 2 The second plate 106 and the isolated positive pole column correspond to Figure 2 The first pole 102 in the start positive pole corresponds to Figure 2 The second pole 103 and the negative pole correspond to Figure 2 The third pole 107 in the main control IC corresponds to Figure 2 The main control chip 105 and the current monitoring IC correspond to Figure 2 The current monitoring chip 108 in the vehicle is connected to the main control IC through the CAN signal line or the LIN signal line, and the isolated positive pole is also connected to the DCDC converter (DC converter 200) and the vehicle electrical appliances. In addition, the other end of the DCDC converter is also connected to the high-voltage power battery.

[0054] from Figure 3-Figure 5 It can be seen that the negative pole can be directly connected to the vehicle body ground through a wiring harness, and the starting positive pole is directly connected to the positive plate of lead dioxide inside the battery, and is externally connected to the car's starter 400 to provide power for starting the vehicle.

[0055] The isolated positive pole is connected to the positive plate inside the battery through a power switch device (thyristor or MOS tube), and the main control IC is used to control the on and off of the power switch device to control the isolated positive pole. The power switch device is usually in the on state. At this time, the isolated positive pole can be discharged normally to the outside or the high-voltage power battery can charge the battery 100. Then, when the main control IC receives a start signal (12V start signal or LIN signal), it means that the vehicle needs to start the starter at this time. Since the starter consumes a lot of current in a short time, in order to avoid the starter starting process lowering the voltage of the entire vehicle electrical appliance, the main control IC sends a first electrical signal to the power switch device. The power switch device responds to the arrival of the first electrical signal and cuts off the connection between the isolated positive pole and the positive plate, so that the starter cannot be connected to the power supply circuit of the entire vehicle electrical appliance through the isolated positive pole, so it cannot lower the voltage of the entire vehicle electrical appliance.

[0056] At the same time, a current monitoring chip 108, i.e., a current monitoring IC, which can also be understood as a current sensor, is added to the main circuit inside the battery 100 to monitor the current flowing through the negative plate of the battery 100 in real time, i.e., the charging and discharging current of the battery 100 at the current moment, and upload the current to the main control IC. The main control IC obtains the current and voltage of the battery in real time, and can calculate the current battery capacity of the battery 100 in real time by comparing the charging and discharging curves corresponding to the battery burned in the battery. Then, the main control IC can transmit the battery capacity information of the battery 100 to the whole vehicle through the CAN or LIN signal, and provide data for the power management of the whole vehicle. After knowing the current capacity of the battery 100, if the current capacity of the battery is too low, the whole vehicle can also increase the voltage output by the high-voltage power battery by controlling the DCDC converter, so that the high-voltage power battery can charge the battery.

[0057] Refer to the following Figure 3, Figure 3 is a schematic diagram of the first battery working state provided in the embodiment of the present application; Figure 3 It can be seen that at this time, the starting positive pole and the isolated positive pole are connected. From the direction of the arrow, it can be seen that the battery 100 supplies power to the entire vehicle electrical appliances. The DCDC converter needs the voltage output by the battery 100 to start, and then it will conduct the connection between the high-voltage power battery and the entire vehicle electrical appliances, so that the high-voltage power battery can supply power to the entire vehicle electrical appliances. Therefore, when the vehicle is just powered on, the battery 100 supplies power to the entire vehicle electrical appliances.

[0058] Reference Figure 4 , Figure 4 is a schematic diagram of the second battery working state provided in the embodiment of the present application; Figure 4 It can be seen that at this time, the starting positive pole and the isolated positive pole are connected. From the direction indicated by the arrow, it can be seen that the high-voltage power battery supplies power to the vehicle electrical appliances, and the high-voltage power battery charges the battery. Therefore, after the vehicle high-voltage power-on is completed, the high-voltage power battery supplies power to the vehicle through the DCDC controller, and charges the battery 100 at the same time.

[0059] Reference Figure 5 , Figure 5 is a schematic diagram of the third battery working state provided in the embodiment of the present application; Figure 5 It can be seen that at this time, the starting positive column and the isolated positive column are in a disconnected state. From the direction indicated by the arrow, it can be seen that the high-voltage power battery only supplies power to the entire vehicle electrical appliances. When the starting positive column is connected to the starter and the starting signal is transmitted to the main control IC through the CAN signal or the LIN signal, the main control IC will output a first electrical signal to act on the power switching device, that is, the switch unit 104, and then the power switching device cuts off the connection between the isolated positive column and the positive plate. At this time, the charging circuit between the high-voltage power battery and the battery will also be disconnected. At this time, the starting positive column of the battery 100 only supplies power to the starter 400, and the high-voltage power battery only supplies power to the entire vehicle electrical appliances. Therefore, the voltage drop caused by the starter during the starting process will not interfere with the entire vehicle electrical appliances.

[0060] In addition, Figure 5 After the vehicle startup process is completed, the vehicle will inform the main control IC through the CAN signal or LIN signal. The main control IC outputs a second electrical signal to act on the power switch device. The power switch device responds to the second electrical signal to restore the connection between the isolated positive pole and the positive plate. The positive pole will also be disconnected from the starter. The restored state is referred to Figure 4 At this time, the high-voltage power battery supplies power to the vehicle battery through the DCDC converter and charges the battery at the same time.

[0061] Reference Figure 6 , Figure 6is a schematic diagram of a battery control system provided in an embodiment of the present application, which is applied to a battery 100. Figure 6 It can be seen that the battery 100 includes: a first pole plate 101, a first pole 102, a second pole 103, a switch unit 104 and a main control chip 105; the system includes: a DC converter 200, a power battery 300 and a starter 400; wherein the DC converter 200 is connected in series between the first pole 102 and the power battery 300, and the second pole 103 is connected in series between the first pole plate 101 and the starter 400; the main control chip 105 is used to output a first electrical signal to the switch unit 104; the switch unit 104 is used to respond to the first electrical signal and cut off the connection between the first pole 102 and the first pole plate 101, so that the voltage of the battery 100 is output from the second pole 103 to the starter 400.
