Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions of the embodiments may be combined with each other, but it is necessary to base that the technical solutions can be realized by those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should be considered to be absent and not within the scope of protection claimed in the present utility model.
The utility model provides a control circuit of an energy storage converter, referring to fig. 1, the control circuit of the energy storage converter comprises a power input end 10, a control module 20, a switch module 30 and a relay circuit 40, wherein the power input end 10 is electrically connected with the control end of the switch module 30 through the control module 20, the power input end 10 is electrically connected with the current input end of the relay circuit 40, the first conduction end of the switch module 30 is electrically connected with the current output end of the relay circuit 40, the second conduction end of the switch module 30 is grounded, and the normally open contact of the relay circuit 40 is electrically connected with a trigger module 50 of the energy storage converter.
Optionally, the power input terminal 10 is configured to receive a power input, such as a +12v dc power supply.
Optionally, the control module 20 is configured to receive a control signal sent by the host computer (or other control devices that establish communication connection with the control module 20), and control, according to the control signal, on or off between the first conductive end and the second conductive end of the switch module 30 through the control end of the switch module 30.
Optionally, if the control end of the switch module 30 receives the low level input of the control module 20, the first conducting end and the second conducting end of the switch module 30 are disconnected; if the control end of the switch module 30 receives the high level input of the control module 20, the first conduction end and the second conduction end of the switch module 30 are conducted.
It should be appreciated that normally open contacts are typically provided in pairs. Therefore, the two normally open contacts of the relay circuit 40 may be electrically connected to the two positive and negative trigger contacts of the trigger module 50 of the energy storage converter, respectively (taking the trigger module 50 as a trigger button for example, the positive and negative trigger contacts are the two positive and negative contacts of the button (the two contacts are closed when the button is pressed and the two contacts are opened when the button is not pressed)).
Since the second conducting end of the switch module 30 is connected to the ground GND, when the first conducting end and the second conducting end of the switch module 30 are disconnected, the current output end of the relay circuit 40 cannot be grounded, so that a current loop cannot be formed between the power input end 10 and the relay circuit 40, and the relay circuit 40 works in a normally open state (at this time, the normally open contact is not closed); when the first conducting end and the second conducting end of the switch module 30 are conducted, the current output end of the relay circuit 40 may be grounded through the switch module 30, so that the power input end 10 and the relay circuit 40 may form a current loop, and thus the relay circuit 40 works in a closed state, that is, the normally open contact is closed, the two positive and negative trigger contacts of the trigger module 50 of the energy storage converter are conducted, so that the trigger module 50 is activated, and the energy storage converter is started (for example, the BAT voltage is controlled to charge the bus to start the device).
In this way, the relay circuit 40 can not only control whether the triggering module 50 of the energy storage converter is triggered or not, but also isolate the low-voltage circuit at the control circuit end of the energy storage converter from the high-voltage circuit at the energy storage converter end by the relay circuit 40, and can play a role in protecting the control circuit of the energy storage converter from isolating high voltage so as to prevent the circuit board corresponding to the control circuit of the energy storage converter from being burnt out by high voltage.
In an embodiment, the user only needs to use corresponding equipment to send corresponding control instructions to the control module 20, so that the remote start of the energy storage converter can be realized, and the process is very convenient; in addition, the triggering module 50 of the original energy storage converter is reserved by the arrangement of the embodiment, namely, in other scenes, a user can still directly start the energy storage converter through the triggering module 50.

The singlechip can control the connection or disconnection between the first pin and the second pin by utilizing an internal logic circuit.
Optionally, when the singlechip needs to output a high level to the control end of the switch module 30 (i.e. when the energy storage converter needs to be started), the first pin and the second pin are controlled to be conducted, so that the current input by the power input end 10 flows to the control end of the switch module 30 through the first module and the singlechip circuit U1; when the singlechip needs to output a low level to the control end of the switch module 30 (i.e. no energy storage converter needs to be started), the first pin and the second pin are controlled to be disconnected, so that the current input by the power input end 10 cannot flow to the control end of the switch module 30 through the first module and the singlechip circuit U1.
And, the singlechip is also responsible for receiving control signals sent by the upper computer (or other control equipment with communication connection with the control module 20). If the control signal is received, the energy storage converter is judged to be required to be started currently, and if the control signal is not received, the energy storage converter is judged to be not required to be started currently.
