As shown in fig. 4, the layer C is configured, and different items only need to be configured depending on the system electrical principle and the hardware interface.
Software interfaces between 3 layers only need to pass through an upper interface and a lower interface, wherein the M mode and the F function only need to be interacted through a mode state and a function state; the F function layer and the C configuration layer only need to interact through the function state and the control state.
Various modes of the MFC will be described in detail in the following examples.
The M-mode layer comprises at least one battery state, and the F-functional layer comprises at least one function and at least one state identifier.
As shown in fig. 1, when in the uplink interface, the M-mode layer receives the functional state identification signal of the F functional layer, and changes the current battery state according to the functional state identification signal.
In particular, in one possible embodiment of the M-mode, the current battery status may be displayed to the user via a display device, such as in a charging car, and the battery status may be displayed on a console display screen, through which the user knows the current charging phase of the battery.
Illustratively, the M-mode layer partitions 8 large states: 1 default state, 2 dormant state, 3 low voltage power-on state, 4 self-checking state, 5 high voltage power-on state, 6 high voltage power-down state, 7 high voltage stop state and 8 low voltage power-down state.

When the mobile terminal is in uplink, the M mode layer only needs to care about the function state identification reported by the F layer, the current battery electrical state is not needed to be known directly from the bottom layer, the bottom layer difference is shielded, when the electrical state of the bottom layer is changed, the realization of the M layer is not needed to be changed, and only the corresponding function in the F layer needs to be modified. The F layer only concerns the electrical parameters, does not need to concern specific hardware, and only reads corresponding functional configuration from the C configuration layer, so that different functions can be realized by using different electrical parameters, and hardware changes at the bottom layer are shielded.
As shown in fig. 1, in the downlink interface, the M-mode layer module receives a modification of the current battery state and generates a mode state control signal according to the modified battery state. Illustratively, the user modifies the current state to the charging state in the user interface, e.g., from a default state to a self-test state.
After the state of the M layer is modified, the M layer transmits the mode state control signal to the F functional layer module, and the F functional layer module receives the state control signal generated by the M mode layer module.
As shown in fig. 3, the F function layer may include a plurality of functions, and each function parses the state control signal after receiving the state control signal, and reads the configuration from the C configuration module.
As shown in fig. 4, the C configuration module may include a plurality of different configurations, and different functions are configured to correspond to different conditions of opening and closing of the switches in the battery module, and different functions of the F function layer generate control signals according to the state control signals received from the M layer and the configuration conditions in the C configuration layer, so as to control the opening and closing of the switches.
In one specific embodiment, as shown in fig. 5, the layer C configuration for this high voltage schematic is as follows:
main positive relay configuration: and a hardware interface is configured, the opening and closing are controlled through the functional state of the F functional layer, the relay is closed in a high-voltage electrifying state, and other states are opened.
Pre-charging relay configuration: and a hardware interface is configured, the opening and closing are controlled through the functional state of the F functional layer, the relay is closed in a pre-charging state, and the other states are opened.
As shown in fig. 6, a main relay and a negative relay are added to the high-voltage schematic diagram, the layer M is unchanged, the layer F is unchanged, and the relay is controlled to adjust on the layer C. The configuration of the C layer at this time is as follows:
main positive relay configuration: and a hardware interface is configured, the opening and closing are controlled through the functional state of the F functional layer, the relay is closed in a high-voltage electrifying state, and other states are opened.
And (3) configuring a main relay and a negative relay: and a hardware interface is configured, and the opening and closing, the pre-charging and high-voltage electrifying states of the relay are controlled to be closed, and other states are opened through the functional state control of the F functional layer.
Pre-charging relay configuration: and a hardware interface is configured, the opening and closing are controlled through the functional state of the F functional layer, the relay is closed in a pre-charging state, and the other states are opened.
It can be seen from this embodiment that only the configuration of the C configuration layer needs to be modified after the addition of the main negative relay, while neither the M layer nor the F layer is modified.
In another specific embodiment, as shown in fig. 7, the layer C configuration for this high voltage schematic is as follows:
configuration of a charging positive relay: and a hardware interface is configured, the relay is closed through the charging function of the F functional layer, and the relay is opened through other functions.
For the high-voltage schematic diagram, the M layer is unchanged, the F layer is added with a charging function module, as shown in fig. 8, and the relay is controlled to adjust on the C layer, as shown in fig. 9.
Layer C is as follows:
configuration of a charging positive relay: configuring a hardware interface, closing the relay through the charging function of the F functional layer, and disconnecting the relay through other functions
Negative charger configuration: configuring a hardware interface, closing the relay through the charging function of the F functional layer, and disconnecting the relay through other functions
In this embodiment, at first increase the function of charging on the F layer, secondly the control relay number is different on C layer, and the function difference only needs to increase 1 function on the F layer, and different relay configurations then accomplish consequently on the C layer, no matter how the outside electricity changes, the M layer is unchangeable, and the F layer increases (can accomplish most) according to the function demand, and the C layer is according to different hardware adaptations.
