Abstract

The invention provides an energy storage device and a charging and discharging system, and relates to the technical field of electronic circuits. The energy storage device comprises an external port used for being connected with an external device; a voltage conversion device, which is connected with the external port; and an energy storage unit, which is connected with the external port and the voltage conversion device, and is used for carrying out charging and discharging through the external device after voltage compensation of the voltage conversion device. The device can solve the problem that in existing energy storage equipment, performance requirement and cost of the voltage conversion device are high.

Description

technical field [0001] The present application relates to the technical field of electronic circuits, in particular, to an energy storage device and a charging and discharging system. Background technique [0002] Energy storage devices (such as batteries, etc.) can discharge loads that require electricity after charging. In this way, the energy storage device can be used repeatedly, and thus has a wide range of applications. [0003] In the prior art, in order to control the charging and discharging current of the energy storage device, a voltage conversion device may be used to perform corresponding regulation. For example, when charging, the voltage conversion device can convert the voltage to a suitable voltage to control the charging current of the energy storage device; when discharging, the voltage conversion device can convert the voltage of the energy storage device to the voltage required by the load to control the storage voltage. discharge current of the device...
