Case Matrix flexible charging stack
explain: Invention patent: zl201510124712.9 product definition is a highly integrated system that integrates all or part of charging modules of electric vehicle charging station together to form a success rate pool, and conduct centralized monitoring and scheduling. It can dynamically and automatically match the optimal number of charging modules according to the actual demand power of electric vehicles in the charging process, and it is a highly integrated system for rapid charging of multiple electric vehicles. Application scope: social public charging station, bus charging station, special vehicle charging station, hybrid charging station, applicable models of charging stack, automatically compatible with different communication protocol versions, applicable to various types of electric vehicles at present and in the future. Technical parameters Product Overview: Based on the principle of "compatible with the present and the future of Daji", OTEX launched the second generation charging equipment matrix flexible charging stack in 2014 (invention patent No.: zl201510124712.9). This technology realizes power sharing and on-demand distribution, which can not only meet the current situation of long-term coexistence of large and small charging power, but also adapt to the development of high-power charging technology in the future. It greatly improves the utilization rate of charging power and equipment, and has great economic and social benefits. Aotechun matrix flexible charging reactor has passed the national product appraisal in 2015. The appraisal committee believes that the product has filled in the domestic blank and the overall technology has reached the domestic leading level. On December 1, 2017, Shenzhen local standard "technical requirements for flexible charging stack of electric vehicles" was released and implemented. Main technology power integration + dynamic distribution flexible charging control technology wide range output technology highly integrated design and process active power factor correction technology full digital control technology comprehensive monitoring + multiple protection technology big data analysis + expert diagnosis technology product advantages compatible with the present Daji future compatible with the present: it can meet the charging requirements of all models and different powers, and dynamically match the required charging power for the electric vehicles connected to any terminal; Daji future: in the future, it can meet the demand of high-power and fast charging of electric vehicles, and avoid repeated investment caused by equipment upgrading and reconstruction or charging station reconstruction.

explain: (1) Working principle of active power filter (APF) CT, real-time detection of the load current, DSP digital signal processor decomposes and calculates the collected signal, extracts the harmonic component in the load current, and then controls the output PWM signal to make IGBT work, so as to control the inverter to produce a current with the same magnitude and opposite direction as the load harmonic to inject into the power grid to compensate the harmonic current and realize the filtering function. Product features: various compensation modes can be configured flexibly, harmonic, reactive power and three-phase unbalance can be compensated, and the priority can be set freely. Instantaneous response time is less than 50 μ s, and full response time is less than 5 ms The user-friendly human-computer interaction interface is equipped with local 4.3-inch touch screen monitoring. The power quality information (voltage, current, power factor, etc.) of the system can be observed in real time through the interface, and the local start-up and stop operation can also be carried out. At the same time, it has a remote communication interface, which can monitor and control the start and stop of remote real-time through GPRS or mobile phone app; the compensation process is fully automatic detection and operation, and the equipment will be automatically cut off in case of failure, and it will be put into use automatically after the failure recovery, without any human intervention The modular design shortens the supply cycle and has high dimensional compatibility. Any power module can be connected in parallel, and the combination of parallel units is free and flexible; the module cooling fan can adjust the fan speed automatically according to the change of output capacity and ambient temperature, so as to achieve low noise and low loss.
