Abstract

The invention discloses a method for measuring the electric quantity of a flywheel battery and the flywheel battery. The method for measuring the electric quantity of the flywheel battery comprises the following steps: testing a motor external characteristic curve of the flywheel battery; determining the charging efficiency of the flywheel according to the motor external characteristic curve of the flywheel battery and the rotating speed of the motor; charging the flywheel battery to be saturated by constant power, current and voltage; recording the charging time, and calculating the actual charging capacity of the flywheel battery. According to the electric quantity measurement method of the flywheel battery, mechanical loss of the flywheel is considered, and the electric quantity accuracy of the flywheel battery is improved.

Description

technical field [0001] The invention relates to the field of flywheel batteries, in particular to a method for measuring the power of a flywheel battery and the flywheel battery. Background technique [0002] In the related art, for the total power of the flywheel battery, the total power obtained by the flywheel battery is obtained by measuring the charging power and integrating according to time, but this calculation method of calculating the total power of the flywheel battery ignores the flywheel battery itself The mechanical loss of the flywheel battery leads to errors. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, an object of the present invention is to propose a method for measuring the power of the flywheel battery, which improves the accuracy of the power of the flywheel battery by considering the mechanical loss of the flywheel. [0004] The present invention ...
