[0045] Referring to Figures 1 to 3 , in order to solve the drawback that the traditional charging management method in the prior art is difficult to adapt to in-vehicle cadmium telluride power generation in this embodiment, the present invention provides a solar vehicle charging management method based on cadmium telluride power generation glass. The management method pre-sets the charging stages of the in-vehicle charging battery in advance according to the power generation characteristics of the cadmium telluride power generation glass and the working specifications of the in-vehicle charging battery, and then outputs a current and voltage that match the charging stages of the in-vehicle charging battery according to the power generation characteristics of the cadmium telluride power generation glass, so as to meet the requirements of cadmium telluride power generation and battery charging. That is, it effectively solves the drawback that the traditional charging management method in the prior art is difficult to adapt to in-vehicle cadmium telluride power generation.
[0046] Specifically, the present invention provides a solar vehicle charging management method based on cadmium telluride power generation glass in the first aspect, including: obtaining the layout specification information of the cadmium telluride power generation glass, such as collecting the DC bus voltage and current output by the cadmium telluride power generation glass, and the layout orientation, so as to determine the output information of the cadmium telluride power generation glass. At the same time, obtain the working specification information of the in-vehicle charging battery, such as the voltage and state information of the battery, so as to control the working condition of the in-vehicle charging battery. Then, according to the working specification information of the in-vehicle charging battery, pre-set multiple working stage information of the in-vehicle charging battery; in a feasible embodiment, the multiple working stage information of the in-vehicle charging battery can be pre-set as: trickle charging, pre-charging, constant current charging, constant voltage charging, and charging cut-off standby and other stages, and at the same time, pre-determine the voltage and current parameters of the in-vehicle charging battery in each stage, so as to realize staged charging of the in-vehicle charging battery and ensure the charging response speed and efficiency of the in-vehicle charging battery. Then, according to the working specification information of the in-vehicle charging battery and the layout specification information of the cadmium telluride power generation glass, pre-set the working adjustment information of the in-vehicle charging battery, that is, the output current and voltage of the cadmium telluride power generation glass can be adjusted through the working voltage and current parameters of different stages of the in-vehicle charging battery. In a feasible implementation manner, the output current and voltage of the cadmium telluride power generation glass can be adjusted by adjusting the duty cycle in the cadmium telluride power generation glass. When adjustment is required, the real-time working state of the in-vehicle charging battery and the real-time output information of the cadmium telluride power generation glass can be collected and obtained in real time, and then the to-be-adjusted state information of the in-vehicle charging battery is determined; then, the to-be-adjusted state information of the in-vehicle charging battery is matched with the multiple working stage information of the in-vehicle charging battery, and combined with the working adjustment information of the in-vehicle charging battery, the charging switch of the in-vehicle charging battery is determined. That is, according to the real-time state of the in-vehicle charging battery and the power output situation of the cadmium telluride power generation glass, control the charging process to switch between different stages, and realize efficient charging management of the in-vehicle charging battery. That is, in this embodiment, the multiple working stage information of the in-vehicle charging battery can include: trickle charging, pre-charging, constant current charging, constant voltage charging, and charging cut-off standby.
[0047] In this embodiment, to facilitate understanding of how to determine corresponding adjustment operations according to different working stages of the in-vehicle charging battery, in this embodiment, the following phased description is provided.
[0048] Specifically, during the trickle charging stage, when the voltage of the in-vehicle charging battery is lower than the preset trickle charging end voltage, the output current is controlled to be less than or equal to the preset trickle current value; if the voltage of the in-vehicle charging battery does not rise to the trickle charging end voltage within a certain time, it is reported that the in-vehicle charging battery is damaged and charging is stopped. That is, the normal operation of the in-vehicle charging battery can be determined based on different reactions during the trickle charging stage of the in-vehicle charging battery.
[0049] Specifically, during the pre-charging stage, when the voltage of the in-vehicle charging battery is higher than the trickle charging end voltage and lower than the pre-charging end voltage, the output current is controlled to be less than or equal to the preset pre-charge current value; if the input power is insufficient, the output current is maintained at the maximum current.
[0050] Specifically, during the constant current charging stage, when the voltage of the in-vehicle charging battery is higher than the trickle charging end voltage and lower than the constant current fast charging end voltage, the output current is controlled to be equal to the preset constant current charging current value; if the input power is insufficient, the output current is maintained at the maximum current.
[0051] Specifically, during the constant voltage charging stage, when the voltage of the in-vehicle charging battery is equal to or higher than the constant current fast charging end voltage, the output voltage is controlled to be maintained at the constant current fast charging end voltage value, and as the battery power of the in-vehicle charging battery increases, the charging current gradually decreases.
[0052] Specifically, during the charging cut-off standby stage, when the voltage of the in-vehicle charging battery is equal to or higher than the constant current fast charging end voltage and the output current is less than the preset cut-off charging current value, the current output is stopped.
[0053] Refer to Figure 2 and Figure 3, in the second aspect, the present invention provides a solar vehicle charging management system based on cadmium telluride power generation glass, adopting a solar vehicle charging management method described in any one of the first aspect. The management system further includes: a sampling circuit, a boost circuit, and a processor. The sampling circuit is electrically connected to the output terminals of the vehicle-mounted charging battery and the cadmium telluride power generation glass respectively. The sampling circuit is used to collect the DC bus voltage and current output by the cadmium telluride power generation glass, as well as the voltage and status information of the vehicle-mounted charging battery. The boost circuit is electrically connected to the output terminal of the cadmium telluride power generation glass and the input terminal of the vehicle-mounted charging battery. The boost circuit is used to boost the electrical energy of the DC bus and then charge the vehicle-mounted charging battery. The processor is electrically connected to the input terminal and output terminal of the cadmium telluride power generation glass, the sampling circuit, and the boost circuit respectively. The processor is used to run the vehicle-mounted charging battery charging management software, and according to the information collected by the sampling circuit, control the duty cycle of the boost circuit according to a preset charging management strategy to achieve the charging management of the vehicle-mounted charging battery. That is, in this embodiment, the processor controls the sampling circuit to collect the power generation status of the cadmium telluride power generation glass and the working status of the vehicle-mounted charging battery, and then adjusts the power generation status of the cadmium telluride power generation glass according to the working status of the vehicle-mounted charging battery. To enable the processor to control the switching of the charging process at different stages according to the real-time status of the vehicle-mounted charging battery and the power output of the cadmium telluride power generation glass, and achieve efficient charging management of the vehicle-mounted charging battery.
[0054] In this embodiment, in order to facilitate the separate monitoring of each charging stage of the vehicle-mounted charging battery, the management system further includes: a charging monitoring management module, a trickle charging module, a pre-charging module, a constant current charging module, a constant voltage charging module, and a charging cut-off standby module. When the processor runs, each module controls the switching of the charging process at different stages according to the real-time status of the vehicle-mounted charging battery and the power output of the cadmium telluride power generation glass.
[0055] Refer to Figure 3, in this embodiment, to facilitate understanding of how to adjust the power generation state of cadmium telluride photovoltaic glass according to the working state of the vehicle-mounted charging battery, the boost circuit includes: a switching transistor Q, a high-frequency low-resistance inductor L, a low-resistance diode D, and a high-frequency low-resistance capacitor C. The switching transistor Q is connected to the output terminal of the cadmium telluride photovoltaic glass. The switching transistor Q is used for controlling current conduction and cut-off, and can also adjust the duty cycle. The high-frequency low-resistance inductor L is electrically connected to the output terminal of the cadmium telluride photovoltaic glass, and is used for filtering, energy storage and energy release. The low-resistance diode D is electrically connected to the switching transistor Q and the high-frequency low-resistance inductor L, and is used for unidirectional freewheeling. The high-frequency low-resistance capacitor C is electrically connected to the low-resistance diode D and the switching transistor Q, and is also electrically connected to the vehicle-mounted charging battery. The high-frequency low-resistance capacitor C is used for buffering and voltage regulation to achieve stable output current and voltage.
[0056] Referring to Figure 2 , in this embodiment, to facilitate understanding of how to switch the charging according to different working stages of the vehicle-mounted charging battery described above, the following is an example for illustration. Specifically,
[0057] Step 1: Combine the working specifications of the vehicle-mounted charging battery to determine the voltage and current specifications of the vehicle-mounted charging battery in each stage of charging management (that is, the voltage and current parameters of the vehicle-mounted charging battery in stages such as trickle charging, pre-charging, constant current charging, constant voltage charging, and charging cut-off standby).
[0058] For example, a certain commercial box truck is equipped with a lithium iron phosphate battery (i.e., the vehicle-mounted charging battery), with a rated capacity of 460 Ah, a rated voltage of 502 V, a working voltage of 390 - 502 V, a charging voltage of 390 - 510 V, and a maximum continuous charging current of 250 A. The design specifications of the battery charging management can be initially determined. C (the current of the rated capacity) is 250 A. The end voltage (Vtc) of the trickle charging of this battery is 390 V, and the trickle current (Itc) is 0.05C. The end voltage (Vpre) of the pre-charging is 410 V, and the pre-charging current (Ipre) is 0.2C. The end voltage (Vreg) of the constant current fast charging is 510 V, and the constant current (Icc) is 0.3 - 1C. The end current (Iterm) of the constant voltage slow charging is 0.2C. At the same time, there are a total of 3 facades on this vehicle type, and a total of 16 standard-sized cadmium telluride photovoltaic glasses with an equivalent area of 1.6 * 1.2 M2 are paved. For example, a certain commercial cadmium telluride photovoltaic glass has an area of 1.92 m 2 , under standard test conditions (illumination of 1000 W / m 2, with a rated output electric power of 290 W at 25°C, that is, a total rated output electric power of 4640 W. It is estimated that the output DC bus input voltage Vdc is 60 V, the current I dc is 77 A, the charging voltage Vout is 390 - 510 V, and the current Iout is 12 - 9 A. In the case of on-vehicle integration, it is impossible to achieve this power in actual output because the lighting effects on different facades certainly cannot reach the optimal value simultaneously.
[0059] Step 2: Detect the state of the on-vehicle charging battery by sampling the output voltage situation of the circuit, and then detect the power state of the cadmium telluride photovoltaic glass by sampling the output voltage and current of the cadmium telluride photovoltaic glass. Voltage control and current control of the charging voltage can be performed by adjusting the duty cycle of the boost circuit.
[0060] Step 3: Use the charging monitoring management module, trickle charging module, pre-charging module, constant current charging module, constant voltage charging module, and charging cut-off standby module in the management system to set the working states of the on-vehicle charging battery to: 1 - charging monitoring management, 2 - trickle charging, 3 - pre-charging, 4 - constant current charging, 5 - constant voltage charging, 6 - charging cut-off standby.
[0061] Step 4: Enter the charging monitoring management function and keep running full-time. Specifically, use the sampling circuit to regularly monitor the output voltage Vout and current I out of the cadmium telluride photovoltaic glass, that is, the charging voltage and charging current of the on-vehicle charging battery. Based on the Vout on-vehicle charging battery voltage, judge the state of the on-vehicle charging battery and call the corresponding charging management module: 2 - trickle charging, 3 - pre-charging, 4 - constant current charging, 5 - constant voltage charging, 6 - charging cut-off standby.
[0062] During 2 - trickle charging: When the on-vehicle charging battery voltage Vout is lower than Vtc (390 V), enter this module. At this time, the on-off time of the switch tube Q can be controlled by adjusting the PWM duty cycle to control the output current Iout to be less than or equal to Itc (0.05C, that is, 7.5 A). If the voltage of the on-vehicle charging battery does not rise to Vtc (390 V) within a certain time (1 hour), then start 6 - cut-off standby and report that the on-vehicle charging battery is damaged.
[0063] During 3 - pre-charging: When the on-vehicle charging battery voltage Vout is higher than Vtc (390 V) and lower than Vpre (410 V), enter this module. Among them, the processor can control the on-off time of the switch tube Q by adjusting the PWM duty cycle in the boost circuit to control the output current Iout to be less than or equal to Ipre (0.2C, that is, 50 A). If the input power is insufficient, the input current remains at the maximum current.
[0064] During 4-constant current charging: When the vehicle-mounted charging battery voltage Vout is higher than Vtc (390V) and lower than Vreg (510V), it enters this module. At this time, the processor controls the on-off time of the switching transistor Q by adjusting the PWM duty cycle in the boost circuit, so that the output current Iout is equal to Icc (0.3C, that is, 75A). If the input power is insufficient, it remains at the maximum current.
[0065] During 5-constant voltage charging: When the vehicle-mounted charging battery voltage Vout is equal to or higher than Vreg (510V), it enters this module. The processor continues to control the on-off time of the switching transistor Q by adjusting the PWM duty cycle in the boost circuit, so that the output voltage Vout is maintained at Vreg (510V). Due to the change in the equivalent resistance after the increase in the vehicle-mounted charging battery power, the charging current will gradually decrease.
[0066] During 6-cutoff standby: When the vehicle-mounted charging battery voltage Vout is equal to or higher than Vreg (510V) and the output current Iout is less than Iterm (0.2C, that is, 50A), it enters this module. At this time, the processor adjusts the PWM duty cycle in the boost circuit so that the adjusted PWM duty cycle is 0, that is, the current output is turned off.
[0067] In some embodiments, the management system can communicate using any currently known or future-developed network protocol such as HTTP (Hyper Text Transfer Protocol), and can be interconnected with digital data communication in any form or medium (for example, a communication network). Examples of communication networks include local area networks ("LAN"), wide area networks ("WAN"), the Internet (for example, the Internet), and end-to-end networks (for example, ad hoc end-to-end networks), as well as any currently known or future-developed networks.
