Abstract: An energy storage module with bypass circuit is provided. The energy storage module includes a first battery pack, a first capacitor, a bypass circuit and a bidirectional isolated converter. The first capacitor is electrically connected between the positive bus connection terminal and the first positive battery terminal or between the negative bus connection terminal and the first negative battery terminal. The bypass circuit is electrically connected to two terminals of the first capacitor. The first positive and negative connection terminals of the bidirectional isolated converter are electrically connected to the positive and negative bus connection terminals respectively or are electrically connected to the first positive and negative battery terminals respectively. The second positive and negative connection terminals of the bidirectional isolated converter are electrically connected to the two terminals of the first capacitor respectively. When the energy storage module enters a bypass mode, the bypass circuit bypasses the first capacitor.

Abstract: An energy storage system includes a DC bus, an energy storage converter, n first battery racks and m energy storage units. The DC bus has a positive bus and a negative bus. The energy storage converter is electrically connected to the DC bus. Each of the n first battery racks is electrically connected between the positive bus and the negative bus directly. Each of the m energy storage units includes a second battery rack and a DC/DC converter. The DC/DC converter is electrically connected between the corresponding second battery rack and the DC bus. The DC/DC converter performs electric energy conversion between the corresponding second battery rack and the DC bus.

Abstract: An energy storage module includes a bus connection part, a battery pack, a capacitor and a series compensation DC conversion device. A first conduction terminal of the series compensation DC conversion device is electrically connected with a positive bus connection terminal and a negative bus connection terminal of the bus connection part, or the first conduction terminal is connected with a battery positive terminal and a battery negative terminal of the battery pack. A second conduction terminal of the series compensation DC conversion device is electrically connected with two terminals of the capacitor. A four-quadrant DC/DC converter of the series compensation DC conversion device controls the capacitor to generate a compensation voltage to compensate a voltage between the two terminals of the battery pack, or the four-quadrant DC/DC converter adjusts a current flowing through the battery pack to a set value.

Abstract: An energy storage module with bypass circuit is provided. The energy storage module includes a first battery pack, a first capacitor, a bypass circuit and a bidirectional isolated converter. The first capacitor is electrically connected between the positive bus connection terminal and the first positive battery terminal or between the negative bus connection terminal and the first negative battery terminal. The bypass circuit is electrically connected to two terminals of the first capacitor. The first positive and negative connection terminals of the bidirectional isolated converter are electrically connected to the positive and negative bus connection terminals respectively or are electrically connected to the first positive and negative battery terminals respectively. The second positive and negative connection terminals of the bidirectional isolated converter are electrically connected to the two terminals of the first capacitor respectively. When the energy storage module enters a bypass mode, the bypass circuit bypasses the first capacitor.
