Detailed Description
Example 1
In order to meet the requirement of continuously supplying power to the airplane load when the power grid is in a flash break, a battery system, a charger (namely a charging module) for supplementing the power of the battery, a high-voltage relay at a direct current side and a control system are required to be added on the basis of the original airplane ground static power supply. The control system is used for communicating with a battery BMS system, controlling a high-voltage relay on a direct current side and controlling a charger, and a schematic diagram of the miniature energy storage system is shown in figure 1.
The distribution transformer and the alternating current distribution switch that the miniature energy storage system was got into to the alternating current input electricity, distribution transformer supply other equipment power supplies such as the air conditioner, distribution transformer can carry out inside power supply through UPS to alternating current-direct current conversion switching power supply, perhaps exports through UPS to alternating current power supply, and UPS still possesses the backup battery power supply to prevent the alternating current input outage.
After the alternating current input electricity enters an alternating current distribution switch of the miniature energy storage system, the alternating current input electricity passes through the charging module and then enters the battery system, the battery system enters the high-voltage relay, the high-voltage relay and the anti-reverse diode are finally output on a power direct current bus, and the control system is used for communicating the battery BMS system and controlling and connecting the high-voltage relay on the direct current side with the charger.
As shown in fig. 1-2, in a normal condition of the power grid, the ground static variable power supply is rectified and inverted and then directly supplies power to the airplane. Under the normal power supply of a power grid, a control system (a controller in fig. 2) and a battery system perform data interaction through CAN communication, check whether the battery system is fully charged in real time, and control a charging module (a charger) to supply power to the battery system (a power supply) when the battery system is detected to be charged. After the ground static variable power supply is started, the voltage on the direct current side is rectified to rise. And when the control system detects that the voltage of the power supply bus is higher than the current voltage of the battery system, the high-voltage relay is closed, and the battery system is communicated with the power supply direct-current bus.
When the power grid drops or flashes, the rectified voltage of the power supply diode is not enough to support the aircraft load to supply power, the voltage of the power supply direct-current bus drops to the voltage of the battery system, and the battery system provides the power supply direct-current bus voltage support to continue to supply power to the aircraft load. When the power grid is recovered, the rectifying voltage of the power diode is higher than the voltage of the battery system, and the energy storage battery system is automatically switched to the ground static power supply for supplying power. At the moment, if the battery system needs to be supplied with power, the control system schedules the charging module to charge the battery system.
The communication topology is shown in fig. 2, and the control system (controller) communicates with the ground static variable power supply, the charging module (charger), and the battery system (BMS) through the CAN. The control system needs to acquire real-time information of the battery system and the power supply and can control whether the high-voltage relay is closed or not according to the running state of the power supply, the voltage of a power bus and the voltage information of the battery system. When the battery system needs to be supplied with power, the control system controls the charging module to work through CAN communication.
The working principle of the system is as follows:
the battery system is connected with a power supply direct current bus through a high-voltage relay and an anti-reverse diode, and the control system controls the high-voltage relay on the battery system side to carry out power-on and power-off operation on the battery system. The control system detects the voltage of the direct current bus of the power supply in real time, when the voltage of the direct current bus of the power supply is higher than the voltage of the battery system and the power supply is in a working state, the high-voltage relay at the side of the battery system is closed, the battery system is connected with the direct current bus of the power supply at the moment, and due to the effect of the anti-reverse diode, the direct current bus power supply of the power supply cannot charge the battery system.
When the power grid drops or flashes, the ground static power supply cannot continuously maintain the voltage of the power supply direct-current bus, the voltage of the power supply direct-current bus drops to be consistent with the voltage of the battery, and the system maintains the voltage of the power supply direct-current bus through the battery system at the moment. The whole system provides the power demand of the airplane load through a battery system, and the power supply of the airplane can be continuously and normally used.
When the power grid is recovered, the rectified voltage of the power diode is higher than the voltage of the battery system, and the whole system is switched to a ground static variable power supply for supplying power.
In order to ensure that the battery system has enough electric quantity, the control system needs to schedule the charging module to supply power to the battery system, the battery system adopts a lithium titanate battery, and the single under-voltage threshold of the lithium titanate battery is 2.9 v.
Example 2
The method for supplementing power to the battery system is shown in fig. 3, and comprises the following steps:
step 1): the control system and the battery system perform data interaction through the switch, and check whether the battery system is fully charged in real time;
step 2): when the control system detects that the battery system needs to be charged, the control system controls the charging module to supplement power to the battery system, and when the control system detects that the battery system is fully charged, the control system stops supplementing power by the charging module;
step 3): the control system sends communication to the charging module and controls the charging module to work, and the charging module responds to the communication of the control system and supplements power to the battery system;
step 4): the control system detects whether the battery system is fully charged or not, and controls the charging module to be disconnected with the battery system and finish power supplement if the battery system is fully charged; and if the battery system still needs to be charged, the control system sends communication to the charging module to continuously supply power to the battery system.
