Charging method and device capable of automatically identifying adapter and photovoltaic input

Abstract

The invention discloses a charging method capable of automatically identifying an adapter and photovoltaic input, and the method comprises the following steps: receiving a first triggering signal sent by an energy storage device, and detecting the initial charging condition of the energy storage device in response to the receiving of the first triggering signal; when the initial charging condition meets the requirement, a startup instruction is issued, whether a first voltage value is smaller than or equal to a second voltage value or not is judged within preset time, the first voltage value is the current charging port voltage, and the second voltage value is the difference value between the charging port voltage before startup and a voltage drop reference value of a photovoltaic input port; and when the first voltage value is smaller than or equal to the second voltage value, marking the photovoltaic charging mode as the current working mode, otherwise, marking the adapter charging mode as the current working mode. Compared with the prior art, the charging port of the energy storage power supply can adapt to adapter input and photovoltaic pole plate input, normal charging is achieved, and a user can insert different or the same input source randomly when using the charging port.

Description

technical field [0001] The invention relates to the technical field of energy storage power supplies, in particular to a charging method and device capable of automatically identifying adapters and photovoltaic inputs. Background technique [0002] The application of energy storage power supply provides great convenience for a variety of outdoor activities, emergency power supply and other production and living scenarios. The market demand for energy storage power supply products is increasing, and at the same time, users are more concerned about the charging speed of energy storage power supply, There are also higher requirements for charging flexibility and charging safety. At present, the charging port of the existing adapter charging and the charging port of the photovoltaic plate are separated and independent from each other, and the user can only use the adapter or the photovoltaic plate to charge separately. Existing energy storage equipment cannot recognize the adap...

AI Technical Summary

Problems solved by technology

Existing energy storage equipment cannot recognize the adapter input and photovoltaic input, and cannot be charged normally when the connection does not match, resulting in problems such as limited charging speed, small charging capacity, and poor charging flexibility. The normal approach is often to upgrade the energy storage system and expansion

However, upgrades and expansions are not unlimited, and the resulting substantial increase in costs and many secondary security issues also make many technicians stop on this issue
