Problems solved by technology

In this case, when the SOC of one battery pack is 0%, it becomes impossible to continue flying even if the SOC of the other battery packs is not 0%.
That is, the energy of other battery packs cannot be effectively used
This means that the actual flight distance becomes shorter than what would otherwise be possible with the full power of multiple battery packs
[0003] In addition, variations in the charge and discharge rates and depth of discharge among multiple battery packs also occur due to variations in the load among multiple motors, and variations also occur in the degree of progression of the state of deterioration (SOH: State Of Health)

Abstract

A plurality of battery packs (51-58) respectively supply current to a plurality of motor drive units (31-38), and the plurality of motor drive units (31-38) drive a plurality of motors (21-28) mounted on a moving body (1). The preliminary battery pack (59) supplies current to at least one of a plurality of first current paths connecting the plurality of motor drive units (31-38) and the plurality of battery packs (51-58), or absorbs current from at least one of the plurality of first current paths. The control unit (70) controls the plurality of first switches (S11-S18) and the plurality of second switches (S21-S28) to adjust the balance of capacities between the plurality of battery packs (51-58).

Description

technical field [0001] The present invention relates to a power supply system for a mobile body and a flying body mounted on a mobile body provided with a plurality of motors. Background technique [0002] In an air vehicle having a plurality of motors, such as an unmanned aerial vehicle, etc., a plurality of battery packs are mounted (for example, refer to Patent Document 1), and a plurality of motors and a plurality of battery packs are connected to each other on a one-to-one basis. In the case of the connection method, the remaining capacity (SOC: State Of Charge) among the plurality of battery packs varies due to variations in the loads among the plurality of motors. In this case, when the SOC of one battery pack is 0%, even if the SOC of the other battery packs is not 0%, it becomes impossible to continue the flight. That is, the energy of other battery packs cannot be effectively used. This means that the actual flight distance becomes shorter than the flightable dis...
