The present disclosure relates to a system and method to determine a readiness of a power conditioning module before initiating a transfer of charge to an energy storage unit.
Figure 1 illustrates an architecture depicting a system [100] configured to determine a readiness of a power conditioning module before initiating a transfer of charge to an energy storage unit. The system [100] comprises a power conditioning module [102], a switch [104], an energy storage unit [106], and an energy management system [108].
Further, the system [100] comprises a control unit [110] in addition to the above-mentioned components, namely, the power conditioning module [102], the switch [104], the energy storage unit [106], and the energy management system [108].
As stated earlier, the system [100] is configured to determine the readiness of the power conditioning module [102] before initiating the transfer of charge to the energy storage unit [106]. The system [100] may be installed fully on-board to an energy consuming device or may be installed partially on the energy consuming device. The energy consuming device may include, but not limited to, a vehicle, a power bank, and a power distributive system.
The power conditioning module [102], hereinafter referred as PCM [102], is the most crucial component of the present system [100]. The PCM [102] is configured to receive power from at least one external power source. The external power source may include, but not limited to, a grid supply and power from a power bank. In other words, the PCM [102] is configured detect the

power from the external power source. As the name suggests, the PCM [102] is configured to condition the received power as per the requirements of the energy storage unit [106], herein after referred as ESU [106]. In an event where the ESU [106] requires AC supply, the PCM [102] provides AC supply whereas, in another event where the ESU [106] requires DC supply, the PCM [102] provides the DC supply. The PCM [102] comprises various converters for changing a phase of the received power supply, a magnitude of the received power supply, and a type of the received power supply. This change is made based on the requirement of the ESU [106]. The PCM [102] is configured receive data regarding the phase, the magnitude, the type of power from the external power source via a CAN communication, a cloud communication or any other such mean that is obvious to a person ordinary skilled in the art. In an embodiment, the PCM [102] may be configured to receive a requirement demand of the ESU [106] from the energy management system [108], herein after referred as EMS [108]. The PCM [102] is configured to receive and transmit communication to the EMS [108] via a wired/wireless communication. The wired communication may include, but not limited to, a USB communication and a CAN communication. The wireless communication may include, but not limited to, a Wi-Fi communication, Bluetooth communication and a cloud communication. Further, the PCM [102] may be located on-board the energy consuming device or may be located off-board the energy consuming device.
In an embodiment, the PCM [102] may comprise of various sub-components, namely, an electro-magnetic interference (EMI) module, a power factor correction (PFC) unit, a DC to DC converter unit. The EMI module shields the PCM [102] from the external electro-magnetic interference. In other words, the EMI module acts as a filter for the PCM [102]. Further, the PFC unit is configured to receive the power supply from the external power source. Furthermore, the PFC unit is configured to correct a power factor and boost a voltage. Basically, the PFC unit comprises a rectifier, a boost circuit and a data acquisition unit. The

rectifier receives the power from the external power source and converts the power in DC. The DC power gets passed through the boost unit to increase the voltage. The data acquisition unit is configured to collect a data from the external power source/power lines. The data may be grid input voltage, input current, temperature, etc. The data acquisition unit is also configured to collect the data of the voltage from the boost unit or any internal PFC information. The data acquisition unit is further configured to communicate the data to the DC to DC converter unit. The DC to DC converter may be a phase shift full bridge (PSFB) unit. The voltage is also passed from the boost unit to the DC to DC converter unit. The DC to DC converter unit comprises an H bridge architecture, an isolation module, and a rectifier module. The H bridge architecture receives the power from the boost unit. The H bridge architecture is configured to convert the power into AC. The AC is then passed through the isolation module. Further, the AC is then passed through the rectifier module and converted to the DC. This DC is finally sent to the switch [104] of the ESU [106]. Furthermore, the DC to DC converter unit also comprises a control card in addition to the components explained above. The control card is configured to receive the data from the data acquisition unit. The control card is also configured to collect data such as output voltage/current (DC magnitude), temperature, etc. The control card also acts a controller to control the supply for current or voltage from the DC to DC converter unit. Lastly, the control card is also configured to send wakeup signals to the EMS [108].
In short, the PCM [102] module is configured to condition the received power as per the requirement of the ESU [106]. Further as explained in the embodiment, the PCM [102] is configured to detect a power from the external power source for charging the ESU [106]. The PCM [102] is also configured to send a wakeup signal to the EMS [108] and to check a first condition of the EMS [108]. The first condition includes regular working of the EMS [108]. The check includes transmitting a command to the EMS [108], wherein the command is one of a

switch-ON command and a switch-OFF command. Based on the command, the EMS [108] is further configured to transmit the command to the switch [104]. Further, the PCM [102] is configured to receive a response from the EMS [108] corresponding to an action of the switch [104]. In an event the response received from the EMS [108] conforms to the command, the regular working condition of the EMS [108] is attained, and the system [100] determines the readiness of the PCM [102] to initiate the transfer of the charge to the ESU [106]. In another event, wherein the first working condition fails to achieve the regular working, the system [100] determines the non-readiness of the PCM [102] to initiate the transfer of the charge to the ESU [106].
As used hereinabove, the term switch [104] refers to any electrical/electronic device capable of switching/breaking ON or OFF the circuit. The switch [104] may include but not limited to, a MOSFET and/or an electrical switch.
In simpler words, in an event, the PCM [102] commands the EMS [108] to switch OFF the switch [104]. The EMS [108] switches OFF the switch [104] and checks whether the power supply from the PCM [102] is able to reach the ESU [106] or not. The PCM [102] is configured to receive the response from the EMS [108]. In an event, wherein the PCM [102] commands to switch OFF the switch [104] and the response from the EMS [108] shows that the power has failed to reach the ESU [106], this condition is determined as the regular working condition of the EMS [108]. However, in an event, wherein the PCM [102] commands to switch OFF the switch [104] and the response from the EMS [108] shows that the power has reached the ESU [106], this condition is determined as lacking the regular working condition of the EMS [108].
Similarly, in an event, wherein the PCM [102] commands switch ON the switch [104] and the response from the EMS [108] shows that the power has reached the ESU [106], this condition is determined as the regular working condition of the EMS [108]. However, in an event, wherein the PCM [102] commands to

switch ON the switch [104] and the response from the EMS [108] shows that the power has failed to reach the ESU [106], this condition is determined lacking the regular working condition of the EMS [108].
Further, the EMS [108] is an electronic system configured to manage the needs of the ESU [106], to protect the ESU [106] from abnormal conditions, to balance the ESU [106], etc. The EMS [108] comprises of a controller to take decisions for managing the above-mentioned tasks. Further, the EMS [108] also performs a check and determines the readiness of the PCM [102] for initiating the transfer of charge to the ESU [106]. The EMS [108] checks a second condition of the PCM [102]. The second condition includes a regular current calibration of the PCM [102]. The regular current calibration of the second condition corresponds to a pre-determined/specified relationship between a current detected by the EMS [108] and the current sent by the PCM [102]. In other words, the current detected by the EMS [108] is the magnitude of current which actually reaches the ESU [106] from the PCM [102] and that reading is passed to the EMS [108] as the current detected. The predetermined/specified relationship may include, but not limited to, a linear relationship, a parabolic relationship and a hyperbolic relationship. In an event, the second condition corresponds to the pre¬determined/specified relationship, the PCM [102] is determined to be ready for initiating the transfer of charge. Similarly, in an event, wherein the second condition fails to match with determined/specified relationship, the PCM [102] is determined to lack readiness for initiating the transfer of charge.
Furthermore, as illustrated in Figure 1, the system [100] comprises the control unit [110]. The control unit [110], hereinafter referred as CU [110], is located on an energy consuming unit. The CU [110] is the master controller of whole of the energy consuming unit and is responsible for controlling the energy consuming units. The CU [110] may include, but not limited to, a micro-processor, mini¬computer and a processor. The CU [110] is also configured to control the EMS

[108]. Further, the CU [110] is configured to check a third condition, a fourth condition, and a fifth condition. The third condition includes a lock state a key, whereas, the fourth condition includes a lock state of a solenoid lock. However, the fifth condition includes a checking of the first condition and the second condition.
As used hereinabove, the lock state of the key refers to a condition wherein, the energy consuming unit is in OFF/un-operational state. In an event, wherein the PCM [102] is off-board the energy consuming unit, the lock state of the solenoid lock refers to a condition in which a socket of the PCM [102] is fully engaged with a socket of the energy consuming unit under the influence of the solenoid. However, in an event, wherein the PCM [102] is on-board the energy consuming unit, the lock state of the solenoid lock refers to a condition in which a power line coming from the external power source is fully engaged with the PCM [102] under the influence of the solenoid. Lastly, the CU [110] determines that the PCM [102] is ready to initiate the transfer of the charge in an event, the third condition is the lock state of the key, the forth working condition is the lock state of the solenoid lock, and the fifth condition is the regular working of the EMS [108] and the regular current calibration of the PCM [102].
Further, Figure 2 illustrates the method [200] for determining a readiness of the PCM [102] before initiating the transfer of charge to the ESU [106]. The method [200] flow initiates at step 202.
At step 204, the PCM [102] detects the power from the external power source for transferring the charge.
At step 206, the PCM [102] checks a first condition of the EMS [108].
At step 208, in an event the first condition is regular working condition, the PCM [102] is determined to be ready for initiating the charge transfer and the charge

transfer initiates. Alternatively, the method [200] may go back to step 206 or terminates to step 214.
At step 210, the EMS [108] checks the second condition of the PCM [102].
At step 212, in an event the second condition of PCM [102] is regular current calibration, the PCM [102] is determined to be ready for initiating the charge transfer and the transfer of charge starts. Alternatively, the method [200] may gc back to step 210 or terminates to step 214.
In an embodiment, the method [200] may comprise of an additional step and the transfer of charge starts based on the completion of the last step.
In the last step, the CU [110] checks the third condition, the fourth condition, and the fifth condition.
In an event, the third condition is the lock state of the key, the fourth condition is the lock state of the solenoid lock, and the fifth condition is the regular working of the EMS [108] and the regular current calibration of the PCM [102], the PCM [102] is determined to be ready for initiating the charge transfer and the transfer of charge starts. Alternatively, the method [200] may go back to checking of the third condition, the fourth condition, and the fifth condition or terminates step 214.
