The implementation of the present utility model will be described in detail below with reference to specific embodiments.
Referring to fig. 1 and 2, a preferred embodiment of the present utility model is provided.
The utility model provides an energy storage power supply for compensating self-discharge phenomenon of a battery by utilizing an electrochemical principle, which comprises the following components:
A battery body and a battery case.
Specifically, the battery body is disposed inside a battery case, and an electrochemical device for storing chemical energy and converting the stored chemical energy into electric energy is disposed on the battery case.
More specifically, a step-up and step-down circuit is provided inside the battery case, and the step-up and step-down circuit is electrically connected with the battery main body and the electrochemical device, respectively, and the step-up and step-down circuit is used for transmitting the electric energy of the electrochemical device to the battery main body so as to charge the battery main body.
More specifically, the battery main body may be regarded as a power storage source in the conventional technology for storing and releasing electric energy, and it should be noted that, in the power storage source in the market, the self-discharge phenomenon occurs at all times in the battery, which results in a decrease in the battery voltage, a phenomenon that the battery voltage is lower than the lowest charging voltage of the charger when the battery is not operated for a long time, and the service life of the battery is also affected when the battery voltage is too low for a long time.
More specifically, in conventional methods, high voltage forced charging may be used, the battery may be removed directly in parallel with the high voltage battery to be forced charged, or (this high voltage is relative to the battery voltage) either the battery may be removed to select an appropriate power source for charging, or the battery may be replaced.
In the embodiment provided by the utility model, the battery shell is arranged on the battery main body, the electrochemical equipment is arranged on the battery shell, the electrochemical equipment can convert stored chemical energy into electric energy and transmit the electric energy into the battery main body through the step-up and step-down circuit, so that the battery is charged, and the situation that the battery voltage is too low to charge due to long-time non-use of the energy storage power supply is prevented.
It can be understood that the charging achieved by the electrochemical device is very micro-charging, and it is not possible to make the battery not need additional charging to supplement the electric quantity, but rather to make the electric quantity in the battery body not drop to a state where it cannot be charged due to the self-discharge phenomenon.
The utility model provides an energy storage power supply for compensating the self-discharge phenomenon of a battery by utilizing an electrochemical principle, which has the following beneficial effects:
According to the invention, the battery shell is arranged outside the battery body, and the electrochemical equipment is arranged on the battery shell, so that the electrochemical equipment converts chemical energy stored in the battery into electric energy, and the battery body is charged through the step-up and step-down circuit, so that the electric quantity consumed by the battery due to a self-discharge phenomenon is made up, the electric energy in the energy storage unit is kept at a certain level, and the problem that the battery cannot be charged due to too low voltage caused by long-time non-use of the energy storage power supply in the prior art is solved.
Preferably, the battery case is provided with a mounting structure in which the electrochemical device is detachably disposed.
It will be appreciated that the chemical energy stored in the electrochemical device is limited, and thus the electrical energy provided by the electrochemical device is limited, and thus the time for placing the battery body due to the self-discharge phenomenon is limited by the electrochemical device to compensate for the battery body.
Preferably, the device further comprises a power detection device.
Specifically, the electric quantity detection device is arranged in the battery shell, and is electrically connected with the battery body and used for collecting data of electric quantity information of the battery body.
Preferably, the charging device is further comprised;
Specifically, the charge interruption device is electrically connected with the electric quantity detection device, and the charge interruption device is used for interrupting the charging of the electrochemical device to the battery body when the electric quantity of the battery body is full.
It can be understood that the electrochemical device continuously converts chemical energy into electric energy and transmits the electric energy to the battery body, and the continuous charging mode causes certain loss to the battery body, so that in order to avoid the loss to the battery body caused by continuous charging, the electric quantity detection device and the charging interruption device are required to be arranged in the energy storage power supply, so that the charging is stopped when the electric quantity of the battery is sufficient, and the loss to the battery caused by overcharging is avoided.
Preferably, the charging interrupt device is a switch closing unit;
Specifically, the switch closing unit is arranged on the buck-boost circuit and is used for controlling the communication and interruption of the buck-boost circuit.
Specifically, when the charge detection device detects that the battery body is full of charge, the switch closing unit interrupts the step-up and step-down circuit to stop charging the battery body, and when the charge detection device detects that the battery body is not full of charge, the switch closing unit closes the step-up and step-down circuit to start charging the battery body.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
