POWER STORAGE SYSTEM
Document Type and Number:
Japanese Patent JP2023120496
Kind Code:
A
Abstract:
To provide a power storage system that can suppress increase in cost and creation of ground space.SOLUTION: A power storage system comprises a multiple-parallel converter system. In the multiple-parallel converter system, an input of a step-up converter is connected to a + input of a loading device. In precharging during a startup, an upper switching element of the step-up converter is switched, and a duty of switching is changed in accordance with a power conduction current measured by a current sensor, a capacitor voltage is measured by a voltage sensor, and the precharging is terminated when it has become equal to a predefined voltage.SELECTED DRAWING: Figure 1
