ELECTRIC POWER SUPPLY SYSTEM, TRANSPORT VEHICLE USING ELECTRIC POWER SUPPLY SYSTEM, AND CONTROL METHOD OF ELECTRIC POWER SUPPLY SYSTEM

摘要

FIELD: electricity. ^ SUBSTANCE: electric power supply system having many energy storage modules, each of which is rechargeable, includes power bus electrically connecting the loading device to electric power supply system. Modules of converters are located between energy storage modules and power bus respectively. Each of them is provided with possibility of controlling the charge-discharge of the appropriate energy storage module. There is device for receiving the temperature from energy storage modules. Device for determining target power value determines target power value for each of many energy storage modules by distributing the required power value from the loading device in compliance with temperatures of energy storage modules which have been received by means of temperature receiving device. Control device of converters controls modules of converters in compliance with target power value determined with the device for determining the target power value. ^ EFFECT: increasing control efficiency of temperature of energy storage modules. ^ 10 cl, 9 dwg
