Charging EV from SOLAR PANELS – Bridging the gap!

Introduction:

Solar Energy is one of the inexhaustible sources of energy that comes with a plethora of benefits. Since India is blessed with a copious amount of sunlight,  that could be converted into electrical power by using the latest solar power conversion techniques like using different Solar power panels that enthrall solar energy and transform it into electricity by the photovoltaic (PV) effect. Such energy is also used in electric vehicles. The photovoltaic cells available in the solar panels alters the energy of the sun which is directly used by the electric vehicle.

Solar Panels in Electric Vehicles:

EV Charging Systems and Solar Panels

EV vehicles can be charged by the charge stations powerd by solar panels. There are a lot of advantages of connecting an EV charging system with the solar system, including gas savings, reduction of harmful CO2 emissions, and charging the EV for less.

Installation of a solar panel system for charging electric cars requires to combine the set up with the solar inverters. In order to operate the devices, the energy generated by the solar panels has to be converted from DC (direct current) to AC (alternating current). Similarly fuelling of the EV with solar power also follow the same conversion pattern, wherein the PV cells and silicon semiconductors in the cells absorb it and then transform it into electric energy by the PV effect. This DC power stored in the battery is then transferred to the inverter, which changes it into AC power.  This AC power can now be transferred to homes (V2H) to operate the electrical home appliances as well

.

Cost of installing a Solar Panel:

There are two types of Solar panel systems whose value is directly correlated to its size and kind.  Both of which are mentioned below along with their respective prices:

  1. Off-Grid panel System:

A 1 kW off-grid system generating 4-5 units of electric power costs between Rs 1 lakh to 1.25 lakh

  • Grid-Connected Panel System:

A Grid-connected panel System ranges between Rs 75,000 and Rs 90,000.

Tesla Plans to Create Cars That Run on Lithium-ion Batteries

The launch of electric cars and lithium-ion batteries have transformed the world of convenience and technology. Tesla is not only working for building convenient technology, but also trying to save the environment by designing highbred cars that are faster than the usual. Tesla is targeting to craft a lithium-ion battery that is capable of running a car or an electric truck for around 16 lakh km. Engineers of Tesla are infatuated with designing the world’s most competent and resourceful electric vehicles for more than a decade.

While other nations across the world are climbing to attain a seamless EV environment, Elon Musk has ensured a perfect deal of effectiveness in the field of an electric vehicle with his famous brand Tesla Motors. Consequently, Tesla cars at present travel beyond the usual on a single charge as compared to any other design of EV in the market.

  • Model S, as well as Model X vehicles, are able to travel nearly 600 km or 525 km on a single charge with a 100 kWh pack of battery.
  • Model S and Model X are now able to run with 200 kW on V3 Superchargers as well as 145 kW with V2 Superchargers. Collectively, these developments allow users to recharge the batteries faster by 50 percent as compared to the earlier models.

Why is Tesla Unique?

  • The choice of Tesla for the cylindrical cells is what differentiates the brand’s designs with other manufacturers.
  • The use of a liquid-cool thermal management system is another key feature used to make sure that the cells are operating in their efficiency as well as optimal ways. It further ensures battery life and performance.
  • The lithium-ion batteries use NMC or lithium nickel, manganese, cobalt, and oxide for ensuring positive electrode or cathode of the battery along with the artificial graphite for the battery’s negative electrode or anode.
  • Existing Tesla cars are capable of achieving around 8 lakh km from their batteries before they confront with any major issues.

As per the international market research organization, i.e., IHS Markit (China), 20 percent of the entire vehicles’ sales are to secure some type of electrification till the year 2025. On the other hand, France, as well as the UK, has made a proposition to finish the sale of the cars producing greenhouse gases by the year 2040. The key cost element of an Electric Vehicle is the battery pack. Tesla has kept its battery technology as a carefully guarded top-secret, which has surmounted the technology to a great level.

What’s new in Autodesk Revit 2020

Introduction:

Autodesk Revit is a BIM Software used to create reliable, synchronized and comprehensive Building designs and documentations. This software comes with the advanced features of 3D Visualization, enabling a person to visualize a building before it is constructed.

What is new in Autodesk Revit 2020

The New version of Revit consists of more than 25 new features and enhancements that could link, produce and optimize its users to create more accurate detailed documentation. It could more closely characterize the design extending to detailing and construction.

Features of Autodesk Revit 2020

The new competences of Revit 2020 aims at assisting its users in linking, generating, and boosting their architectural creativities. Other additional features are detailed below:

  1. Convert PDF to Revit:

The new Autodesk Revit allows its users to insert a PDF Document that is placed as a 2D object that could be modified like any other image. Also, if the PDF has a vector Data then it could be snapped to the PDF for quick tracing or drawing the line work or walls of the building.

  • Publish Cloud Models on Revit home:

This feature allows the users to easily navigate and contact different cloud models. SO whenever Revit starts, the new screen emerges simplifying the access to various cloud models, which in turn boosts the workflow efficiency, enabling the users who don’t have access to Revit to watch and refer the respective model in BIM360

  • Create Elliptical and Curtain Walls:

The 2020 version of Revit allows its users to curate Elliptical and curtain walls through the ellipse tool present in the draw panel for walls.

  • New structural Rebar tools:

It also includes a set of new fundamental rebar tools, including rebar copy and move logic, multi-rebar explanation to actual faces, and rebar in model-in-place stairs.

  • Additional Path to travel Tool:

The additional path to travel tool enables the user to determine the shortest distance between two points in ground planning

  • Improved and advanced filters:

The new Autodesk Revit 2020 is a perfect assimilation of a new and improved version of the OR filter functionality, enabling the users to choose a specific OR Filter type and accordingly select a particular parameter.
