In order to better understand the technical solutions, the technical solutions will be described in detail below with reference to the drawings and the specific embodiments of the specification, and it should be understood that the specific features in the embodiments and examples of the present invention are detailed descriptions of the technical solutions of the present application, but not limitations of the technical solutions of the present application, and the technical features in the embodiments and examples of the present invention can be combined with each other without conflict.
Example one
Referring to fig. 2, the circuit for balancing the battery power supply and power management of the vehicle in the present embodiment includes a battery pack side circuit shown in a left dotted frame and a controller side circuit shown in a right dotted frame.
The battery packaging end circuit comprises a battery 1, a battery protection plate 4, a discharge switch 2, a charge switch 3, a charge interface 6, a power supply positive output end BAT + and a discharge protection end P-. The discharging switch 2 and the charging switch 3 are both N-type MOS tubes.
The power supply positive output end BAT + and the discharge protection end P-are the same as circuits of battery power supply and power management of a traditional balance car, namely a fuse 5 is connected between the power supply positive output end BAT + and the positive electrode of the battery 1, the charging switch 3 and the discharge switch 2 are connected between the negative electrode of the battery 1 and the discharge protection end P-, the controlled end of the charging switch 3 is connected with the charge protection signal output port of the battery protection plate 4, and the controlled end of the discharge switch 2 is connected with the discharge protection signal output port of the battery protection plate 4.
In addition, the charging interface 6 is the same as a traditional balance car battery power supply and power management circuit, the negative electrode of the charging interface 6 is connected with the discharging protection end P-, and the positive electrode of the charging interface 6 is connected with the positive electrode of the battery 1.
The improvement of this embodiment and the conventional circuit lies in two aspects, on the one hand, the negative power input end of the controller 9 is connected to the negative electrode of the battery 1, and compared with the two connecting ends of the positive power output end BAT + and the discharge protection end P-between the existing battery pack end circuit and the controller end circuit, this embodiment is equivalent to adding the negative power output end BAT-, so that the controller end circuit can directly take electricity from the battery 1 to avoid power failure due to the discharge protection effect of the battery protection board 4 during discharging.
On the other hand, because the controller end circuit is directly connected with the battery cathode, the discharge protection control of the battery protection board 4 is avoided, so as to implement discharge protection, in this embodiment, the detection end of the controller 9 is connected with the discharge protection end P-so as to monitor whether the battery protection board 4 outputs a discharge protection signal, and when the discharge protection signal is detected, the battery protection board enters a low power consumption state to implement discharge protection.
Specifically, because the type of the controller 9 in this embodiment is selected such that the voltage at each port is less than or equal to 5V, and the signal at the discharge protection terminal P-generally exceeds 5V, in this embodiment, the signal at the discharge protection terminal P-cannot be directly detected by the detection terminal of the controller 9, for this reason, the controller end circuit in this embodiment further includes a discharge protection signal detection circuit, which is connected between the detection terminal of the controller 9 and the discharge protection terminal P-to trigger the controller 9 to enter a low power consumption state when detecting the discharge protection signal of the battery protection board 4.
It will be appreciated that the entry of the controller 9 into the low power consumption state is typically controlled to power down the drive parts thereof, so that it is necessary to determine whether or not power down can be safely performed before entering the low power consumption state, and if so, to enter the low power consumption state.
It should be noted that the low power consumption state is a state that the controller 9 itself can control to enter, and how the state is implemented specifically, this embodiment is not limited, and the state itself does not need to be modified, for example, the low power consumption state may be a sleep state. In this embodiment, the controller 9 only needs to enter this state when detecting that the battery protection board 4 outputs the discharge protection signal.
More specifically, the discharge protection signal detection circuit may employ a voltage divider network. For example, the voltage dividing network includes a first voltage dividing resistor 7 and a second voltage dividing resistor 8, a first end of the first voltage dividing resistor 7 is connected to the positive power output terminal BAT +, a second end of the first voltage dividing resistor 7 is simultaneously connected to a first end of the second voltage dividing resistor 8, the discharge protection terminal P —, and the detection terminal of the controller 9, and a second end of the second voltage dividing resistor 8 is connected to the negative electrode of the battery, i.e., the negative power output terminal BAT-.
It should be noted that, the power supply positive output terminal BAT +, the discharge protection terminal P-, the battery protection board 4, the power supply negative output terminal BAT-, the positive power supply input terminal, and the negative power supply input terminal mentioned herein are not necessarily physical ports, but may be a virtual terminal, and such a virtual terminal represents a connection position of the battery pack side circuit and the controller side circuit.
In addition, the battery protection plate 4 in the present embodiment may not require a specially customized protection plate, and almost any conventional protection plate without communication may be applicable.
In addition, in this embodiment, a fuse is connected between the positive output terminal BAT + of the power supply and the positive electrode of the battery 1. It will be appreciated that a fuse may also be connected between the negative supply input of the controller 9 and the negative pole of the battery 1.
The working principle of the embodiment is as follows: the control of the discharging switch 2 and the charging switch 3 is completely the same as the original control process, and the energy of the battery 1 is directly accessed to the end circuit of the controller without any switching device. When the battery protection board works normally, the discharge protection signal output port and the charge protection signal output port of the battery protection board 4 both output high levels, the switches 2 and 3 between the discharge protection end P-and the cathode of the battery 1 are both conducted to become low resistances, and the voltage division network formed by the resistors 7 and 8 outputs low levels. When the discharge protection occurs, the output port of the discharge protection signal of the battery protection board 4 outputs a low level, the switch 2 between the P & lt- & gt and the cathode of the battery 1 is disconnected to become a high resistance, the voltage division network formed by the resistors 7 and 8 outputs a high level, the controller 9 detects the level change and then considers that the battery protection board 4 outputs the discharge protection signal, and then the controller 9 enters a low-power-consumption dormant state under the condition of ensuring the use safety, so as to wait for charging or fault processing, thereby avoiding the risk of sudden power loss of the controller 9 caused by directly turning off the cathode output of the battery 1 in the traditional battery protection method.
In addition, it should be noted that some ports of the controller 9 can bear a voltage of more than 5V, for example, some controllers have a high-resistance resistor 7 similar to the one in the embodiment already inside, and a diode is also used in the controller to clamp the positive electrode of the controller, so that there is no need to worry about the problem of too large amplitude of the input voltage, and therefore, the detection end of the controller 9 can directly detect the signal of the discharge protection end P-, so that the voltage division network can be omitted, which is also within the protection scope of the present invention.
Preferably, in other embodiments, the control circuit may further include an alarm circuit connected to the controller 9, and the controller 9 may trigger the alarm circuit to activate an alarm when detecting the discharge protection signal of the battery protection board 4, for example, the alarm may be generated by a sound and/or a whistle.
Preferably, the present invention can also provide a mechanical switch for the operator to control, and the mechanical switch is connected between the negative power input end of the controller 9 and the negative electrode of the battery 1. For example, when an operator receives alarm information, the mechanical switch can be turned off manually to turn off the power supply of the control end circuit, and then the mechanical switch can be turned on to control the whole controller end circuit to be powered on again to restore the normal working state. It will be appreciated that the mechanical switch may also be connected between the positive power supply input of the controller 9 and the positive pole of the battery 1.
Preferably, the controller 9 is also designed to be connected to a mechanical wake-up switch for outputting a wake-up signal when pressed. After the controller 9 enters the low power consumption state, if the P-is in the normal signal state (i.e. the controller 9 does not detect the discharge protection signal), the controller 9 recovers to the normal working state if receiving the wake-up signal of the mechanical wake-up switch.
Example two
Referring to fig. 3, the charging switch 3 and the discharging switch 2 in the first embodiment are connected in series in the same path, and compared with the first embodiment, the present embodiment is different only in that the charging switch 3 and the discharging switch 2 are not connected in series in the same path, but in two separate paths. Specifically, the discharge switch 2 is connected between the negative electrode of the battery 1 and the discharge protection terminal P-, the charge switch 3 is connected between the negative electrode of the charge interface 6 and the negative electrode of the battery 1, and the positive electrode of the charge interface 6 is connected with the positive electrode of the battery 1.
In this embodiment, the control of the discharging switch 2 and the charging switch 3 is completely the same as the original control process, and the working principle of this embodiment is the same as that of the first embodiment, which is not described herein again.
EXAMPLE III
Referring to fig. 4, the present embodiment differs from the two previous embodiments in that:
firstly, the composition of the voltage divider network is changed, specifically, the first end of the first voltage divider resistor 7 is connected to the discharge protection terminal P —, the second end of the first voltage divider resistor 7 is connected to the first end of the second voltage divider resistor 8 and the detection terminal of the controller, and the second end of the second voltage divider resistor 8 is connected to the negative electrode of the battery. It is to be understood that, in the first and second embodiments, the voltage dividing network of the present embodiment may also be adopted, and the voltage dividing network of the present embodiment may also adopt the voltage dividing network of the first and second embodiments.
Secondly, the discharge switch 2 in the first and second embodiments is omitted, and the discharge protection signal output port of the battery protection board 4 is directly connected to the discharge protection terminal P-. The connection of the charging switch 3 is the same as in the second embodiment.
The working principle of the embodiment is as follows: the control of the discharging switch 2 and the charging switch 3 is completely the same as the original control process, and the energy of the battery 1 is directly accessed to the end circuit of the controller without any switching device. When the battery protection board 4 works normally, the discharge protection signal output port and the charge protection signal output port of the battery protection board 4 both output high levels, and the voltage division network formed by the resistors 7 and 8 outputs high levels. When the discharge protection occurs, the output port of the discharge protection signal of the battery protection board 4 outputs a low level, the voltage division network formed by the resistors 7 and 8 outputs a low level, and the controller 9 detects the level change, and then the controller 9 can consider that the battery protection board 4 outputs the discharge protection signal, so that the controller 9 enters a low-power-consumption dormant state under the condition of ensuring the use safety, and waits for charging or fault processing, thereby avoiding the risk of sudden power loss of the controller 9 caused by directly turning off the cathode output of the battery 1 in the traditional battery protection method.
To sum up, the utility model discloses a circuit of balance car battery power supply and power management has following beneficial effect: in the utility model, on one hand, the controller directly gets the electricity from the battery and does not get the electricity from the original discharge protection end, so the discharge control of the battery protection board can be avoided, and the power failure caused by the discharge protection function of the battery protection board during the discharge is avoided; in two aspects, in order to realize the protection of discharging, the sense terminal and the protection of discharging end of controller are connected, so can monitor whether the battery protection shield exports the protection of discharging signal, and the controller is detecting get into the low-power consumption state during the protection of discharging signal to can realize the protection of discharging, start from above two aspects, on the basis of guaranteeing the protection of discharging, avoided directly turn-off the risk that battery output leads to the controller to lose electricity suddenly among the traditional battery protection method, moreover the utility model discloses do not need the protection shield of special customization, almost any conventional protection shield that does not have the communication can all be suitable for.
While the embodiments of the present invention have been described with reference to the accompanying drawings, the present invention is not limited to the above-described embodiments, which are merely illustrative and not restrictive, and many modifications may be made by one skilled in the art without departing from the spirit and scope of the present invention as defined in the appended claims.
