At the same time, the term "and / or" used in this specification includes any and all combinations of the relevant listed items.

[0042] In one embodiment, Figure 1 As shown, the present application provides a battery, including a battery pack 100, a negative electrode port 200, at least two positive electrode ports 300, at least two switch modules 400 and a control module 500. The battery pack 100 includes N battery cells connected in series. Figure 1As shown, from right to left, there are the first battery cell, the second battery cell, and ... the Nth battery cell. Each battery cell includes a positive terminal and a negative terminal, and the negative terminal of the i-th battery cell is connected to the positive terminal of the i+1-th battery cell, thereby forming a battery cell group 100 (1≤i≤N-1). Among them, the negative terminal of the N-th battery cell group 100 is connected to the negative terminal 200, and the positive terminal of the i-th battery cell is connected to a switch module 400. Each switch module 400 is respectively connected to a positive terminal 300 and a control module 500, and different switch modules 400 are connected to different batteries and positive terminals 300.

[0043] The control module 500 can be used to control the on / off state of each switch module 400 to supply power to the outside through the negative port 200 and at least one positive port 300. Among them, the supply voltage provided by the negative port 200 and different positive ports 300 is different. The supply voltage provided by the negative port 200 and different positive ports 300 is related to the number of cells connected to the positive port 300. Exemplarily, taking the lithium iron phosphate cell as an example, the cell group 100 is 1P13S, which is composed of 13 lithium iron phosphate cells connected in series, and the total rated voltage that the cell group 100 can provide reaches more than 40V, for example, it can be 48V. The four cells close to the negative port 200 are led out, that is, the positive end of the 10th cell from right to left is connected to a switch module 400, and the supply voltage output through the negative port 200 and the positive port 300 connected to the switch module 400 is about 12V. The control module 500 may be an MCU, and the control module 500 may be integrated into a battery management system or may be independently provided.

[0044] In the embodiment of the present application, the battery includes a cell group 100, a negative electrode port 200, at least two positive electrode ports 300, at least two switch modules 400 and a control module 500. The cell group 100 includes N cells connected in series, the negative electrode port 200 and the negative terminal of the Nth cell are grounded, each switch module 400 is respectively connected to the positive terminal of a cell and a positive electrode port 300, and different switch modules 400 are connected to different cells and positive electrode ports 300. The control module 500 is respectively connected to each switch module 400, and can be used to control the on and off state of each switch module 400, so as to supply power to the outside through the negative electrode port 200 and at least one positive electrode port 300. It can be understood that the negative port 200, part of the battery cells, a switch module 400, and a positive port 300 are connected to form a power supply circuit, which outputs a power supply voltage to the outside through the negative port 200 and the positive port 300, and the magnitude of the power supply voltage is related to the number of battery cells included in the power supply circuit. In this way, only one group of battery cell groups 100 needs to be set up, and at least two battery cells in the battery cell group 100 are respectively connected to a switch module 400, and the on-off state of each switch module 400 is controlled by the control module 500. The required power supply voltage can be output to the outside through the corresponding positive port 300 and the negative port 200. Since the price of the switch is much lower than that of the battery cell, the cost can be reduced.

[0045] In one embodiment, Figure 2 As shown, the battery also includes a voltage conversion module 600. The voltage conversion module 600 is connected to each positive electrode port 300 and the control module 500 respectively, and is used to convert the power supply voltage provided by a positive electrode port into the power supply voltage of at least one remaining positive electrode port under the control of the control module 500. The voltage conversion module 600 can be a DC-DC (direct current-direct current) converter. Exemplarily, the power supply voltage provided by the positive electrode port A and the negative electrode port is 48V, and the power supply voltage provided by the positive electrode port B and the negative electrode port is 12V. The voltage conversion module 600 can convert the 48V voltage provided by the positive electrode port A into a 12V voltage, or convert the 12V voltage provided by the positive electrode port B into a 48V voltage under the control of the control module 500. In this way, when a certain switch module 400 fails and the positive electrode port 300 connected to the switch module 400 cannot output the required power supply voltage, the power supply voltage provided by other positive electrode ports can be converted into the power supply voltage required by the positive electrode port through the voltage conversion module 600, thereby ensuring the normal output of the battery.

[0046] In one embodiment, the battery includes multiple operating modes. Figure 3As shown, at least two switch modules include a first switch module 410 and a second switch module 420. At least two positive ports include a first positive port 310 and a second positive port 320. The first positive port 310 is connected to the first switch module 410, and the second positive port 320 is connected to the second switch module 420. The second switch module 420 is connected to the positive electrode of the battery cell farthest from the negative port 200, and the first switch module 410 is connected to the positive electrode of any remaining battery cell.

[0047] Therefore, the control module 500 is also used to control the on / off state of the first switch module 410 and the second switch module 420, and the working state of the voltage conversion module 600, so that the battery is in a target working mode. The target working mode is one of the normal power supply mode, the sleep power supply mode, the lock power mode, the external jumper mode or the charging mode.

[0048] Exemplarily, the control module 500 is also used to control the first switch module 410 to be in an on state, the second switch module 420 to be in an on state, and the voltage conversion module 600 to be in an off state when the target working mode is the normal power supply mode, so as to supply power to the outside through the negative electrode port 200 and the first positive electrode port 310 and the second positive electrode port 320 respectively. In the normal power supply mode, the first power supply voltage can be outputted to the outside through the negative electrode port 200 and the first positive electrode port 310, and the second power supply voltage can be outputted to the outside through the negative electrode port 200 and the second positive electrode port 320. Exemplarily, the first power supply voltage is 12V, and the second power supply voltage is 24V.

[0049] Optionally, the control module 500 is also used to control the first switch module 410 to be in an off state, control the second switch module 420 to be in an on state, and control the voltage conversion module 600 to convert the second power supply voltage provided by the second positive port 320 into a first power supply voltage, so as to output the first power supply voltage through the negative port 200 and the first positive port 310, and output the second power supply voltage through the negative port 200 and the second positive port 320. Wherein, the first power supply voltage is less than the second power supply voltage. Taking an electric vehicle as an example, the battery cells of the battery cell group 100 will experience a discharge process during the long-term parking of the vehicle, but due to differences in materials and manufacturing processes between different battery cells, the discharge degrees of different battery cells are different, which will cause differences in the voltage levels of each battery cell in the battery cell group 100. Over time, this voltage difference will continue to accumulate, resulting in the voltage of some battery cells being significantly lower than that of other battery cells. When the vehicle is started again, this imbalance between the battery cell voltages will affect the overall performance of the battery cell group 100. In this embodiment, when the battery is in the sleep power supply mode, the first switch module 410 is disconnected, the second switch module 420 is turned on, and the second power supply voltage is provided to the outside through the second positive port 320 and the negative port 200, and the voltage conversion module 600 converts the second power supply voltage into the first power supply voltage, and provides the first power supply voltage to the outside through the first positive port 310 and the negative port 200. In this way, both the first power supply voltage and the second power supply voltage are provided by the entire battery cell group 100, and no balance problem will occur.

[0050] Optionally, the control module 500 is also used to control the first switch module 410 to be in an open state, control the second switch module 420 to be in an open state, and control the voltage conversion module 600 to be in an off state when the target working mode is the power-locking mode, so that the battery does not supply power to the outside.

[0051] When the target working mode is the external charging mode or the charging mode, the first positive electrode port 310 or the second positive electrode port 320 is also connected to an external power source. For example, the external power source may be a charging pile, a fire-fighting device, or other vehicles.

[0052] Optionally, the control module 500 is also used to control the first switch module 410 to be in an off state, control the second switch module 420 to be in an on state, and control the voltage conversion module 600 to convert the first power supply voltage provided by the first positive port 310 into a second power supply voltage when an external power supply is connected to the first positive port 310, so as to charge the battery cell group 100 and / or supply power to the outside through the negative port 200 and the second positive port 320.

[0053] Optionally, the control module 500 is also used to control the first switch module 410 to be in an off state, control the second switch module 420 to be in an on state, and control the voltage conversion module 600 to convert the second power supply voltage provided by the second positive port 320 into a first power supply voltage when an external power supply is connected to the second positive port 320, so as to charge the battery cell group 100 and / or supply power to the outside through the negative port 200 and the first positive port 310.

[0054] In one embodiment, the control module 500 is also used to obtain fault information of each switch module, determine the faulty switch module according to the fault information, and control the voltage conversion module 600 to convert the power supply voltage provided by the positive port connected to the switch module that has not failed to the power supply voltage of the positive port connected to the faulty switch module. The faulty switch module is the switch module that has failed among the switch modules. Exemplarily, after the control module 500 determines that the first switch module 410 has failed according to the fault information, the voltage conversion module 600 can be controlled to convert the second power supply voltage into the first power supply voltage, and output it through the first positive port 310 and the negative port 200 to ensure the normal power supply of the vehicle. After the control module 500 determines that the second switch module 420 has failed according to the fault information, the voltage conversion module 600 can be controlled to convert the first power supply voltage into the second power supply voltage, and output it through the second positive port 320 and the negative port 200 to ensure the normal power supply of the vehicle.

[0055] In one embodiment, Figure 4 As shown, the battery also includes a detection module 700. The detection module 700 is connected to the battery cell group 100 and the control module 500 respectively, and is used to detect the state parameters of the battery cell group 100. The state parameters may include parameters such as current, voltage, and temperature of the battery cell group 100. The control module 500 is also used to obtain the remaining power of the battery cell group 100 according to the state parameters, and control the on-off state of each switch module according to the remaining power. The control module 500 can obtain the remaining power (SOC) of the battery cell group 100 according to the state parameters detected by the detection module 700. When the SOC is lower than the preset value, in order to ensure that the vehicle can start normally the next time it is used, the control module 500 can control each switch module to disconnect. At this time, the battery no longer supplies power to the outside and enters the lock power mode.

[0056] In one embodiment, please refer to Figure 4, the battery also includes a power module 800. The power module 800 is connected to the battery cell group 100 and the control module 500 respectively. Specifically, the power module 800 is connected to the positive electrode of the battery cell farthest from the negative terminal 200 in the battery cell group 100. The power module 800 can be used to convert the output voltage of the battery cell group 100 into the working voltage of the control module 500. The output voltage of the battery cell group 100 is the total voltage that the entire battery cell group 100 can provide. Exemplarily, the output voltage of the battery cell group 100 is 48V, and the working voltage of the control module 500 is 5V. The power module 800 can convert the 48V voltage of the battery cell group into a 5V voltage and output it to the control module 500.

[0057] In one embodiment, the battery also includes a communication port and a hard-wired wake-up pin. The communication port is connected to the control module 500 for realizing the interaction between the control module 500 and the external circuit. The hard-wired wake-up pin is connected to the control module 500 for receiving an external level signal and transmitting the external level signal to the control module 500. The external level signal is used to wake up the control module 500. The external level signal may be issued by a vehicle controller or a domain controller. Exemplarily, when the battery is in a lock power mode, an external controller may send an external level signal to the control module 500 via a hard-wired wake-up pin to wake up the control module 500, and the control module 500 may control each switch module to be turned on, and the battery is powered normally.
