Description

Technical Field

[0001] The utility model relates to the field of solar charging electricity storage, and in particular to a new energy charging electricity device that automatically switches between charging and discharging modes. Background Art

[0002] As an inexhaustible and pollution-free energy source, solar energy is becoming a rising star in the energy market. People are increasingly utilizing solar energy, and solar outdoor power systems have become a common power supply method. Furthermore, with the rapid development of mobile devices such as mobile phones, tablets, smart watches, and smart bracelets, as well as the increase in outdoor activities like long-distance travel and mountain hiking, using solar outdoor power systems to charge mobile devices outdoors has become a necessity. Outdoor activities require electricity in many situations, but traditional power supplies are limited in functionality, inconvenient to carry, and easily depleted, making them difficult to recharge in complex outdoor environments. For this reason, solar panel charging has gained widespread adoption.

[0003] Currently, solar charging devices typically use a single power source for limited-time charging, or manually switch between multiple power sources for charging. When charging a battery, an external power source is used to reverse the battery's chemical reactions, thereby restoring the stored energy. This process is a one-way chemical reaction, and the mutually exclusive nature of battery charging and discharging means that the battery cannot be used while charging. This prevents the automatic switching between charging and power consumption, allowing for both functions to be simultaneously maintained.

[0004] The utility model provides a new energy charging and power-consuming device that automatically switches between charging and discharging modes, which overcomes the problem that the charging and power consumption of energy storage batteries cannot be automatically taken into account at the same time, and realizes the automatic synchronous switching of energy storage and power consumption modes of multiple energy storage batteries, taking power consumption into account while storing energy, thereby achieving the purpose of reducing weight and increasing efficiency, and achieving twice the result with half the effort. Utility Model Content

[0005] The purpose of this utility model is to provide a new energy charging and power-consuming device that automatically switches the charging and discharging modes, so that multiple energy storage batteries can automatically and synchronously switch between energy storage and power consumption modes, taking into account power consumption while storing energy.

[0006] In order to achieve the above-mentioned objectives, the utility model provides a new energy charging and power-consuming device that automatically switches between charging and discharging modes, including a solar panel, at least two energy storage batteries and an interlocking and interlocking automatic power-changing module; wherein, the interlocking and interlocking automatic power-changing module includes a first relay, a second relay and a time-controlled switch; the energy storage battery and the time-controlled switch are connected in parallel between the first relay and the second relay; the first relay in the interlocking and interlocking automatic power-changing module is connected to the solar panel through a solar controller, and the second relay is connected to the external electrical appliance through an inverter.

[0007] In this utility model, the energy storage battery used for charging and energy storage is connected to the solar panel via a first relay to achieve this charging and energy storage function. A second relay disconnects the energy storage battery used for charging and energy storage from an external electrical appliance. The energy storage battery used for power consumption is disconnected from the solar panel via the first relay and connected to the external electrical appliance via the second relay. This allows multiple energy storage batteries to simultaneously charge and consume electricity. A timer is used for timing. When a preset time interval is reached, the timer sends a signal to both relays simultaneously, which control the multiple energy storage power sources to automatically switch between energy storage and power consumption. And so on, in a repetitive cycle.

[0008] Preferably, the present invention has two energy storage batteries. The time-controlled switch controls the two relays to automatically and synchronously switch between the energy storage state and the power consumption state of the two energy storage batteries, that is, linkage interlocking.

[0009] According to the new energy charging power device for automatically switching charging and discharging modes described in the utility model, preferably, the time-controlled switch is used to set the battery replacement interval time of the interlocking automatic battery replacement module, that is, the battery replacement interval.

[0010] According to the new energy charging device for automatically switching between charging and discharging modes described in the utility model, preferably, the first relay and the second relay are intermediate relays.

[0011] According to the new energy charging device for automatically switching charging and discharging modes described in the utility model, preferably, the first port of the first relay is connected to the solar controller via a terminal.

[0013] According to the new energy charging device for automatically switching charging and discharging modes described in the utility model, preferably, the seventh port of the first relay is connected to the time-controlled switch, and the time-controlled switch is also connected to the eighth port of the second relay through a terminal.

[0014] According to the new energy charging device for automatically switching between charging and discharging modes described in the utility model, preferably, the time-controlled switch is a microcomputer time-controlled switch.

[0015] According to the new energy charging device for automatically switching charging and discharging modes described in the utility model, preferably, the first energy storage battery and the second energy storage battery can be one or more of a lithium battery, a sodium battery or a lead-acid battery.
