Detailed Description
In order to make the technical problems, technical solutions and technical effects achieved by the present invention more clear, the embodiments of the present invention will be described in further detail with reference to the accompanying drawings, and obviously, the described embodiments are only some embodiments, not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present invention.
As shown in fig. 1, the embodiment of the present invention provides a charging and discharging control system schematic diagram for intelligently switching multiple power battery packs, and the system 100 includes: a control module 110, a communication module 120, a key wake-up module 130 and a power loop control module 140; optionally, the control module 110 may be a Microcontroller (MCU).
The control module 110 is connected to each battery pack through the communication module 120, and is configured to obtain operating state information of each battery pack. The communication module 120 is implemented by a local Area Network (CAN) communication circuit. Further, referring to fig. 2, each battery pack is provided with a CAN interface, the CAN interface on each battery pack is connected to a general CAN interface of the control system, and by the above connection, the operation state information of each battery pack CAN be sent to the control module 110 through the respective CAN interface. The operation state information of each battery pack may include numerical information such as a voltage value and a battery capacity of each battery pack.
The control module 110 is further connected to the Key-wakeup (Key-wakeup) module 130, and is configured to control the Key-wakeup module 130 to perform wakeup or sleep operation on each battery pack according to the running state information of each battery pack, so as to determine a current target discharge battery pack or a current target charge battery pack. The key wake-up module 130 may control the on/off of the battery pack, and mainly controls the optical coupler switch to wake up or sleep other battery packs by the control module 110.
The control module 110 is further connected to the power loop control module 140, and is configured to control the target discharging battery pack or the target charging battery pack to operate through the power loop control module 140 after determining the current target discharging battery pack or the target charging battery pack. The control system can automatically switch power input and output modes according to the running state information of each battery pack, has high intelligent degree and avoids charging and discharging accidents caused by human reasons.
Wherein the power loop control module 140 is composed of a charging MOS and a discharging MOS.
Further, the system further includes a current detection module 150, where the current detection module 150 is connected to the control module 110 and each battery pack, and is configured to obtain current information during charging and discharging of the battery pack, and send the current information to the control module 110, so that the control module 110 can monitor charging and discharging currents of the battery pack in real time.
Further, the control module 110 is further configured to control the on/off of the power loop control module 140 according to the current information during the charging and discharging processes of the battery pack and the operating state information of each battery pack, so as to protect the circuit.
With continued reference to fig. 1, the system further includes a power supply module 160, where the power supply module 160 is connected to the control module 110, the communication module 120, and the current detection module 150, respectively, and is configured to provide power to the control module 110, the communication module 120, and the current detection module 150. Specifically, the power supply module 160 takes power from the battery and then converts the power into a 5V power supply and a 3.3V power supply through the voltage reduction circuit. The 5V power supply is converted into a 3.3V power supply through the voltage reduction circuit to supply power to the CAN communication circuit and the current detection module 150; the 3.3V power supplies power to the control module 110 and the peripheral circuits.
With continued reference to fig. 1 and 2, the control system is powered by the battery pack, so that at least one group of batteries in the multi-power battery pack provided in the embodiment of the present invention is in an awake state, the group of batteries is set as a main battery, and a power loop of the main battery has output.
Specifically, assuming that the main battery pack (assumed to be the battery pack 1) supplies power to the control system 100 at this time, when the control system 100 operates in the discharging mode, the control module 110 determines the state of the battery pack supplied with power through the CAN communication method, and when the voltage and the capacity of the battery pack are within the reasonable operation range, drives the high-voltage FET driver to turn on the discharging MOS, and then supplies power to the rear-end controller load. When the battery pack is used to a low electric quantity, the control module 110 drives the optocoupler switch to wake up any other battery pack, and if the electric quantity is low, the battery pack needs to be dormant, and then other battery packs continue to be waked up until a battery pack which can be used is waked up.
Assuming that the battery pack 2 is available, during intelligent switching, the high-voltage side FET driver is driven to close the discharging MOS of the 1 st path firstly, and then the discharging MOS of the 2 nd path is opened, at the moment, the whole system can normally operate, and the like.
When the control system 100 is operating in the charging mode, the basic strategy is consistent with the discharging mode. Firstly, whether the capacity of a battery (assumed to be a battery pack 1) of a main battery pack needs to be charged is judged, if so, a high-voltage side FET driver of the battery pack 1 is driven to turn on a charging MOS, when the battery is nearly fully charged, a control module 110 drives an optocoupler switch to wake up any other battery pack, if the electric quantity is high, the battery pack needs to be dormant, and then other battery packs continue to be waken up until the battery pack needing to be charged is waken up, and assumed to be a battery pack 2. When the intelligent switching is carried out, the high-voltage side FET driver is firstly driven to close the charging MOS of the 1 st path, then the charging MOS of the 2 nd path is opened, and at the moment, the whole group of battery pack can be orderly charged once, and the rest can be done in the same way.
Therefore, the system can not only solve the problems of low capacity, short endurance mileage and the like of the battery pack, but also automatically switch power input and output modes, namely, the main battery is charged firstly when charged, and is automatically switched to the next battery to be charged after being fully charged, so that the rest can be done, until all the batteries to be charged are charged, the switching modes of discharging and charging are opposite, the intelligent degree is high, and charging and discharging accidents caused by human factors are avoided.
It should be noted that the foregoing is only a preferred embodiment of the present invention and the technical principles applied. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention. Therefore, although the present invention has been described in greater detail with reference to the above embodiments, the present invention is not limited to the above embodiments, and may include other equivalent embodiments without departing from the scope of the present invention.
