Description
Technical Field
The invention relates to the field of new energy automobile manufacturing, in particular to a power supply system applied to a new energy electric automobile.
Background
In recent years, with the rapid development of economic society, the problems of environmental pollution and world energy crisis become more serious, so that the automobile industry faces serious challenges. The new energy automobile is an automobile with new technology and new structure formed by adopting unconventional automobile fuel as a power source (or adopting conventional automobile fuel and adopting a novel vehicle-mounted power device) and integrating the advanced technology in the aspects of the power device and driving of the automobile.
At present, the existing new energy electric vehicle charging and power storage device is composed of an alternating current slow charging pile, a vehicle-mounted charger, a power battery and the like. The alternating-current slow-filling pile mainly comprises a standing type pile and a wall-mounted type pile, and other installation modes are provided, so that the alternating-current slow-filling pile is generally alternating. The slow filling piles are indoor and outdoor, and the outdoor protection grade is higher. But the principle is the same, namely, the vehicle-mounted charger is provided with 220V alternating current voltage. The ac charging post may also be referred to as an ac power supply, and in addition to the power supply, there is a cable assembly, i.e. a connection device consisting of a cable and a power supply plug. The cable device has a CC resistance value required by the national standard, and the power supply device also has a control guide module which can output a CP signal according to the connection state. The vehicle-mounted charger converts 220V alternating current of a power grid into high-voltage direct current suitable for a voltage platform of a whole vehicle. Most of the power of a common vehicle-mounted charger is 6.4KW, the peak current can reach 20A, the maximum allowable single-phase input of alternating current is 32A alternating current, the vehicle-mounted charger is efficient, so that the power capable of charging the whole vehicle is about 6.4KW approximately, the voltage of a general power grid cannot reach 220V in the peak period of power utilization, and the output power of the charger cannot reach the rated power. The charging time is longer at this time, but the alternating current slow charging is beneficial to prolonging the service life of the power battery. If it is not a matter of special urgency, using communication to keep the population alive is a sensible option. The power battery can be divided into a lead-acid battery, a ternary lithium battery, a hydrogen-nickel fuel battery and the like according to different materials, and compared with the lead-acid battery, the power battery is heavier and has low capacity density; the ternary lithium battery has mature technology and higher energy density, and is a common technical route in the current market; the nickel-hydrogen battery is difficult to popularize due to high cost. The lithium battery charging is divided into three stages, namely a trickle stage, a constant current stage, a constant voltage stage and a terminal charging current which is about 5A, so that the charging of the whole vehicle is generally from 30% to 80%, and the process from 80% to 100% is still long because the time is ideal.
However, new energy vehicles under development, including pneumatic vehicles, pure electric vehicles (such as lithium battery powered vehicles), dimethyl ether vehicles, hydrogen fuel vehicles, gas vehicles, alcohol fuel vehicles, and vehicles using vegetable oil as fuel, have the limitations of short endurance mileage, long charging time, low battery safety performance, and the like, and the charging speed of electric vehicles is closely related to the power of the charger, the charging characteristics of the battery, the temperature, and the like. Under the current battery technology level, even if the battery is charged quickly, the battery needs to be charged for 30 minutes to 80% of the battery capacity, and after the battery exceeds 80%, the charging current needs to be reduced to protect the safety of the battery, and the charging time to 100% is longer. In addition, when the temperature is low in winter, the charging current required by the battery is reduced, and the charging time is longer.

It should be noted that the boost inverter voltage system device further includes: the driving protection circuit comprises a driving booster circuit for adjusting output voltage, an SG3525 closed-loop control driving circuit for protecting the SG3525 control chip, a driving protection circuit for protecting overcurrent, undervoltage and overvoltage of a circuit, a front-stage power tube driving circuit for adjusting the output voltage and a rear-stage power tube driving circuit for adjusting the output voltage; the driving booster circuit, the SG3525 closed-loop control driving circuit, the driving protection circuit, the front-stage power tube driving circuit and the rear-stage power tube driving circuit are connected through a power-on circuit.
Specifically, as shown in fig. 6, the schematic diagram of the driving boost circuit applied to the power supply system of the new energy electric vehicle according to the embodiment of the present application is shown. The current passes through the driving booster circuit, the voltage 25V output by the solar panel 1015 can be filtered by the filter capacitor C97 in the circuit, and the voltage is converted by the direct current voltage stabilizing chip and filtered by the C99 and C100 capacitors, and then the direct current 12V is output.
Further, as shown in fig. 7, the schematic diagram of an SG3525 closed-loop control driving circuit applied to a power supply system of a new energy electric vehicle according to an embodiment of the present application is shown. The driving circuit is controlled by SG3525 closed loop, the circuit is designed to be closed loop control, and when the circuit is operated under light load, the voltage of the circuit after two inversions is about 700V. If the load becomes large, the circuit immediately becomes open loop control, but the circuit operates most efficiently at this time. The 15K resistor and the 2200PF capacitor are respectively connected with the ports of the oscillation capacitor and the resistor, and the frequency of the output end is maintained at 22 KHz. Under the work of the frequency, the switching loss is small, the pressure of the rectifier tube is small, and the efficiency is improved. On the direct current output side, the opening degree of the photoelectric switch is controlled by the output voltage, and in order to enable the pulse width of the output PWM signal to change along with the voltage, the direct current output side needs to feed back a signal to the compensation end. In order to prevent external interference on the normal operation of SG3525 control chip 1018, a pull-down resistor is added to the external turn-off signal input terminal, and the SG3525 control chip is protected by a protection circuit formed by LM 393. In order to prevent the interference and impact of the power supply on the normal operation of the SG3525 control chip, and therefore affect the stability of the waveform, 47UF and 104 capacitors and 10UF and 104 capacitors can be respectively arranged at the bias end of the voltage and the output end of the reference voltage. The on and off of the power tube are controlled by the complementary PWM waveforms output by the 11 pin and the 14 pin. The SG3525 control chip detects the waveform of each output, so that the two MOS tubes can be prevented from being directly connected to break down the tube.
The drive protection circuit is built through an LM393 voltage comparator chip. The principle of the drive protection circuit is that when the voltage of the reverse input end of the voltage comparator is lower than that of the same-direction input end, the output is high level. A voltage division circuit is used for dividing voltage in the reverse input end 1, the voltage is 5.1V of the voltage of the built-in power supply of the SG3525 control chip, and the voltage is divided by the voltage division circuit and then 1.5V of voltage is provided for the reverse input end. When the current is large, the current feedback end of the circuit generates voltage drop and then is compared by the overvoltage comparator, and the output end outputs high level, so that overcurrent protection, undervoltage protection and overvoltage protection of the circuit can be realized.
The front stage power tube driving circuit can be composed of an NPN type triode and a PNP type triode. The upper tube is NPN type, the lower tube is PNP type, PWM signal is input from the base electrode of two triodes, when the high level comes, there is voltage drop between the emitter electrode and the base electrode of the NPN tube, Q2 is cut off, Q1 is conducted, the output is also high level; since the emitters of both the NPN and PNP are high at the previous time, when the PWM goes low from high, Q2 turns on, Q1 turns off, and the output goes low. Each tube on the DC/DC power main board is provided with an independent grid driving resistor, and the output adopts the conventional push-pull output. The drain of the MOS tube outputs a high-frequency low-voltage electricity, then the electricity is boosted through a transformer with a center tap, the conversion from 12V pulse voltage to 380V pulse voltage is realized, and in order to avoid the current from flowing backwards to influence the normal operation of other components, a diode can be connected in series with the drain of the power tube. C23, C24, C25 and C26 are four large-polarity capacitors and play a role in filtering alternating-current components in the direct-current storage battery; the high frequency components in the dc power can be filtered by the small capacitance of these 105C 19, C20, C21 and C22 to reduce the power transistor drain waveform spike. The four rectifier diodes and two capacitors with large capacity form a rectifier filter circuit, wherein the bridge rectifier circuit is composed of MUR1560 rectifier diodes. In the bridge rectifier circuit, the low-frequency alternating current component in the circuit is filtered by a C27 capacitor, the high-frequency alternating current component is filtered by a C32 capacitor, and finally, the high-voltage direct current of 380V is output after passing through a 500V/30A fuse.
The rear-stage power tube driving circuit boosts the voltage again by modifying a transformer with a center tap, and converts the direct-current voltage 380V in the front-stage power tube driving circuit into the direct-current voltage 700V, so that the load energy storage capacitor is charged.
