The use of ladders, the demand for cheap household energy storage systems can provide new ideas for the recycling of electric vehicles.
First, the use of power battery ladder
Countries around the world are actively conducting experimental research and engineering applications in the use of power battery ladders. Many countries have successfully applied engineering and commercial projects.
Typical case of power battery ladder utilization
The overseas energy storage market has started, and the policy is still the driving force.
United States
New York State, load reduction plan. The required project must be completed by June 1, 2016, and each project will be reduced by at least 50kW. Among them, the battery energy storage project subsidies 2,100 US dollars / kW.
Japan
Based on the energy storage system of lithium-ion batteries, a total of 10 billion yen (about 98.3 million US dollars) is allocated, which gives the purchaser 2/3 of the price of the system. The household user limit is 1 million yen ($9846); the commercial user limit is 100 million yen ($982,000).
Germany
Since May 2013, the German Federal Ministry of Economic Affairs has implemented a KfW-energy storage subsidy program to stimulate distributed battery storage. For the photovoltaic facilities of less than 30 kW, the policy stipulates that the energy storage facilities for the simultaneous installation of newly installed photovoltaic power generation should not exceed 600 euros, and the photovoltaic power generation and energy storage facilities should not exceed 660 euros per kilowatt.
Australia
Adelaide's commercial, residential, school, and community users are subsidized to install a “photovoltaic + energy storage†system of up to 5,000 Australian dollars; electric vehicle users are given charging piles, each with a maximum subsidy of AU$500.
Second, overseas energy storage products cut into users through distributed photovoltaic channels
The typical Powerwall “photovoltaic + energy storage†system consists of three core components: PV modules, batteries, and inverters, supplemented by other electrical equipment such as distribution boxes and measuring instruments. SolarCity will offer a 10 degree version of Powerwall to users who have purchased their rooftop solar system. Users will have to pay $5,000 in advance to get a 9-year battery lease. If you want to completely buy out the battery, you need to pay $7,140.
Tungsten carbide welding rope is a type of welding filler material that is used for hardfacing applications. It is made by combining tungsten carbide particles with a binding material, such as nickel or cobalt, to create a rope-like form.
Tungsten carbide is known for its exceptional hardness and wear resistance, making it ideal for applications where the welded surface needs to withstand extreme abrasion and impact. The welding rope is typically used in industries such as mining, oil and gas, construction, and agriculture.
When the tungsten carbide welding rope is heated during the welding process, the binding material melts and fuses the tungsten carbide particles to the base metal, creating a hard and durable surface. This helps to extend the lifespan of equipment and machinery by protecting it from wear and tear.
Tungsten carbide welding rope can be applied using various welding processes, including manual metal arc welding (MMA), gas tungsten arc welding (GTAW), and flux-cored arc welding (FCAW). The choice of welding process depends on the specific application and the equipment available.
Overall, tungsten carbide welding rope offers a cost-effective solution for protecting and repairing high-wear surfaces, making it a popular choice in industries where durability and longevity are essential.
