Climate change is a global problemfacing mankind. With the emission of carbon dioxide and the sharp increase ofgreenhouse gases, it poses a threat to the life system and the whole blueplanet. In this context, countries all over the world reduce greenhouse gasesin the form of global agreement, and countries have set their own carbon peakcarbon neutralization goals. The new energy and electric vehicle industry hasbecome an effective means to achieve this goal. Countries all over the worldhave also formulated their own guidelines and policies for new energy, electricvehicles and energy storage, and vigorously develop clean energy, electricvehicles and energy storage projects. In recent years, electric vehicles havemade rapid development, and the impact of electric vehicles on power grid willbe more and more obvious. If the electric vehicle is used as a mobile energystorage device to effectively guide the charging and energy storage of electricvehicles, it will be able to effectively guide the improvement of the overallenergy structure.

If the number of electric vehicles in acountry is 5 million, the corresponding battery capacity of new energy vehicleswill be about 300 GWH. If the global number of new energy vehicles exceeds 80million and the power storage capacity is about 4800 GWH, new energy vehicleswill be one of the huge mobile energy storage markets in the future. Due to theexisting power generation structure, the environmental protection of electricvehicles in the whole life cycle is controversial. Vehicle electrification mustachieve low-carbon energy, that is, close coordination with renewable energypower generation. If the electric vehicle energy storage is connected to thegrid with renewable energy such as wind power and photovoltaic, the flexiblecharging and discharging of electric vehicles will be realized, the grid loadwill be greatly reduced, and the effective management of electric vehiclecharging will also reduce the investment cost of transmission and distributionto a certain extent. In the next 5-10 years, a large number of electric vehiclebatteries will exit. After retirement, electric vehicle batteries can also beused as energy storage batteries for secondary utilization, which will form ahuge energy storage market.

In short, the coordinated development ofnew energy vehicles and energy storage is an inevitable trend. Renewable energypower generation will be conducive to the coordinated development of new energyvehicles and electric energy storage; At present, the electricity pricestrategy needs to be flexible, gradually liberalize the distributed power salesmarket and create a market environment; Reasonably plan the charging anddischarging behavior of new energy vehicles and improve the flexibility andadjustment space of electric vehicles; Fully explore the system development ofelectric vehicle battery life cycle and power market, which will be conduciveto the optimization and improvement of the overall energy structure.

Vigorouslypromote the energy interaction between new energy vehicles and power grid(V2G), and vigorously develop new energy and energy storage. Charging newenergy vehicles will become one of the main ways of energy utilization in thefuture. In order to promote the sustainable development of mankind, our companyis committed to providing efficient and reliable power energy solutions. Forthe V2G market, our company has launched the two-way conversion module ofAC-DC, which can be applied to the grid connection of solar energy, windenergy, energy storage batteries and power grid, so as to realize the functionof power peak and valley regulation or reduce power grid load, It can also beapplied to various occasions requiring two-way power conversion. The AC-DCbidirectional conversion module of VAPEL will assist in the power conversionbetween the power grid and the energy storage of the battery pack. It is thecharging mode when working in the forward direction. It uses AC (mains power)to charge the battery pack or provide DC voltage for the load, and the singleoutput is adjustable 200-1000Vdc. When working in the reverse direction, it isthe inverter mode, which connects the voltage inverter output of the batterypack or DC voltage source to the grid. Today, let's briefly talk about someapplication schemes of new energy, energy storage and electric vehiclecharging.

1. Chargingsolution for residential area

Mostresidential areas have no surplus transformer load, and cannot access chargingfacilities based on the original power facilities. In the short term, theexpansion cost is high and difficult. According to the current situation of thecommunity, combined with distributed photovoltaic and energy storage, anintegrated optical storage and solar-energystorage-charging station can be built to release electricenergy during peak power consumption and store electric energy during low powerconsumption, so as to provide safe and stable charging services for residentsof the community.

Features

A.Using energy storage system to cut peak and fill valley can not only reduce thepressure of power grid, but also save operation cost;

B.Make rational use of clean energy and reduce the cost of power gridtransformation.

2. Dedicatedhub charging solution

The special hub charging solution is applicableto bus, taxi, sanitation, logistics and other operating or municipal vehicles.Such vehicles have high requirements for rapid power supplement and safecharging. A large number of electric vehicles will be parked and charged in thespecial hub station, and a large number of DC fast charging piles need to beinstalled. According to the current situation of the site, combined withdistributed photovoltaic and energy storage, an integrated optical storage and solar-energystorage-charging station can be built to release electric energy during peakpower consumption and store electric energy during low power consumption.

Features

A. The energy storage system is used to cutpeak and fill valley, reduce the pressure of power grid and save operationcost.

B. The standardized and modular configurationof the system makes the construction of the charging station system moreconvenient and economical.
