What it does
The design of the photovoltaic storage and charging integrated intelligent charging system integrates photovoltaic power generation, energy storage equipment, mobile charging piles, and trams
Your inspiration
During the National Day holiday, my friends and I went out to play with our electric cars. However, the battery life of electric cars made us have great ‘mileage anxiety’, which seriously affected our travelling experience. Specifically, it is difficult to queue up for charging in the service area, it is impossible to quickly identify whether the charging equipment is working properly, the charging time is long and the price of electricity is high, which makes us feel that buying an electric car is not as reliable as a traditional fuel car.
How it works
The optical storage and charging integrated intelligent charging system design consists of four parts: the tram, the mobile charging pile, the charging shed and the charging station. The whole of the tram-changer achieves battery dismantling and installation through three tracks, scissor lifts and mechanical grippers, and stepped cassettes to fix batteries of different widths; secondly, the new slide ramp and vehicle left/right movement device ensure that the vehicle drives smoothly into the interior of the tram-changer; finally, it adopts a full-wrapped chassis structure, and optimises the size of the equipment for the actual vehicle data. Its use scenarios include not only emergency power exchange services on motorways, but also power exchange services within charging stations in service areas, as well as assistance to neighbouring service areas to achieve dynamic adjustment of demand between service areas.
Design process
First of all, using quantitative research methods, crawling 100,000-400,000 price range of electric car reviews, as well as charging pile reviews, crawling a total of 10,000 pieces of data, and then LDA visualisation of the data, in the analysis of electric car data, when λ = 1, the highest weight theme five, accounting for 40.7%, which appeared the highest frequency of the word in order of "charging ‘ (frequency of occurrence is about 250 times), ’range" (frequency of occurrence is more than 200 times). In the analysis of the charging pile comment area crawling data, when λ = 1, the highest weight theme one, accounting for 31.5%, of which the highest frequency of occurrence of the word in order of ‘convenience’ (frequency of occurrence of about 500 times), ‘speed’ (frequency of occurrence of close to 400 times). (frequency close to 400 times). Therefore, we conclude that EV users are more concerned about range and charging, and more concerned about charging speed at charging stations. In the field research, research location one is the Beidaihe service area, and there are a total of four charging methods on site. Universal equipment a total of eight charging piles are in use.
How it is different
Optical storage and charging integrated intelligent charging system design, integration of photovoltaic power generation, energy storage equipment, mobile charging piles and trams, the use of ‘optical storage network’ multi-source complementary power supply, ‘low valley energy storage, peak energy release’ to reduce the cost of electricity and grid dependence; portable charging pile can be The mobile charging pile can be flexibly deployed to meet the needs of different scenarios; the high-speed emergency tram fills the blank of high-speed emergency charging and can dynamically deploy resources; the intelligent management of the whole equipment realises the dynamic and optimal scheduling of energy and digital service;
Future plans
1. Pilot in phases to verify scenario suitability In the short term, verify mobile charging pile scheduling and emergency response capability of tram exchange in highway service areas. After that, we will try to expand to the weak areas of the power grid (such as communities and scenic spots), and fill in the gaps by using off-grid power supply with optical storage. Eventually, we will build a ‘city+highway+countryside’ charging network to achieve dynamic optimisation of resources. 2. Technology optimisation and standardisation Intelligent scheduling platform
