Discussing the Development Prospects of Integrated Electric Vehicle Charging Stations with "Light Storage Charging"
With the gradual development of the new energy vehicle industry, private purchases of new energy vehicles began to emerge in China in 2014, marking the beginning of the first year of new energy vehicles in China. In 2015, the country entered a year of rapid growth in the new energy vehicle industry, and China also became a new energy vehicle market in this year. In terms of sales, the sales of new energy vehicles in China reached 3.521 million units in 2021, a year-on-year increase of 157.6%. For seven consecutive years, it has ranked first in global sales.
Therefore, in the context of uneven development between electric vehicles and charging stations, the integration of "photovoltaic+energy storage+charging" is gradually expanding towards environmental protection, convenience, safety, and other aspects, becoming an innovative attempt in the construction of electric vehicle charging stations. The integrated photovoltaic storage and charging power station can use the energy storage system to store energy at night. During peak charging periods, the energy storage power station and the power grid work together to supply power to the charging station, which not only achieves peak shaving and valley filling, but also saves distribution capacity expansion costs. At the same time, it can effectively solve the problems of intermittency and instability in new energy generation.
At the same time, the integration of light storage and charging can not only solve the problem of distribution networks in limited land resources, but also flexibly interact with the public power grid as needed and operate relatively independently, using new energy as much as possible, alleviating the impact of charging piles on the power grid. In terms of energy consumption, directly using energy storage batteries to charge power batteries improves energy conversion efficiency.
The main features of the integrated light storage and charging system are:
1. Photovoltaic power generation for self use
2. Peak shaving and valley filling in the power grid to reduce electricity costs
3. Intelligent charging and improvement of charging guarantee capability for new energy vehicles
4. Emergency backup power is used as a backup power source during power outages in the power grid
5. Continuous profitability
