Problems solved by technology
[0003] The present invention provides a control method for a marine battery power management system. The optimized output current value of the marine power supply module in the system with the minimum ineffective current heat loss value is obtained through calculation, and the power supply control module is controlled to control the output of the marine power supply module. The optimal output current value is to solve the technical problem that the existing ship battery power system produces local high current output and cause ineffective heating, so as to reduce the ineffective heat loss of the battery electric ship system as much as possible, and then realize the improvement of battery power. Power battery efficiency of ships in operation

The invention discloses a control method of a ship battery power management system. The method includes: the method includes: calculating and obtaining the ship according to load device parameters, power supply device parameters and power supply state parameters, combined with the work requirements of the ship load module; The optimized output current value of the power supply module in the system with the minimum reactive current heat loss value; combined with the load position parameter and the power supply position parameter, the ship power supply module is controlled to output the optimal output current value through the power supply control module. The present invention calculates and obtains the optimized output current value of the marine power supply module in the system with the minimum ineffective current heat loss value, and controls the marine power supply module to output the optimal output current value, thereby reducing the invalid heat loss of the battery electric ship system and realizing the improvement of battery power The power battery efficiency of the ship in operation.
Description
technical field [0001] The invention relates to the technical field of ships, in particular to a control method for a ship battery power management system. Background technique [0002] Generally, the battery unit of the battery-powered ship is used as a battery unit grid-connected system. The working discharge current of the ship’s power battery is passively output due to the demand of the ship’s load, and the current output of the battery unit is based on the passive output of the power system structure and battery parameters, which is prone to local high current output of the system and ineffective heating. In view of the high-power battery power demand of large freight ships in the future, the design cost of ship battery units has always restricted the development, market popularization and operational efficiency of battery-powered ships. In order to improve the power battery efficiency of battery-powered ships in operation, reducing the ineffective heat loss of battery...
