Electric vehicles

  • Objective

    Electrical Vehicles can be connected to the grid, and used to balance the (local) power distribution network. This is a feasible solution for an energy system with a higher penetration rate of intermittent renewable energy generation. Take for example the Netherlands: 6M electric vehicles with an average capacity of 20 kWh, with 20% connected to the network at any given time, providing 50% of the charging rate yields about 6M * 20 * 50% * 30% = 18 GW of instantaneous power, allbeit for a small time-frame.

  • From the house of Hero Electric, India's Largest Electric Vehicle company comes Raahii E-Rickshaw. Raahii is built indigenously with a robust body that requires low maintenance. In addition to a sleek and refined look, attractive interiors, custom fittings and an exceptional finish, it can accommodate four passengers at a time. Its large wheel base and sturdy chassis makes it stable and run smoothly even on sub-standard roads.

  • The Circuit S e- Bus is a zero-emission vehicle, an assurance of a positive, cleaner and greener future for all of us and for the generations to come. It is built to match the country’s unique transport need that is powered by the swappable Smart Battery technology. The Circuit bus is designed keeping in mind the Indian road conditions, the prevailing usage, load conditions and landscape. The driver cockpit is designed to lower driver fatigue and ensure a comfortable drive.

  • Interoperable Smart Mobility solution offers a single energy infrastructure platform for the small electric vehicles such as electric bikes, scooters, e-Rickshaw and e-Auto. The solution comprises of Smart Battery and Quick Interchange Station all linked together through a smart network. Various applications that can be powered by this solution include intracity public transport-bike taxis, last-mile connectivity and contract carriage through e-Auto/e-rickshaw; last mile goods delivery and point-to-point transport services.  

  • Electric vehicle growth poses both challenges and opportunities for the electric grid. The charging of electrical vehicles is an additional demand for electricity and since a majority of charging happens at home end, a lot of the demand for charging can happen in the evenings when people return from work. For the electric grids, it can become expensive to meet the demand at peak periods. 

  • EV chargers are classified as per the speed of charging (slow, fast and rapid) and the whether they provide AC or DC current as an output. However, in general all these chargers are designed to take electricity from grid and not vice versa. If EVs have to also supply electricity back to the grid as is required for Vehicle-to-Grid (V2G) applications then we need bi-directional chargers.

  • A major aspect of why a buyer is deterred from opting an electric vehicle in India is the lack of charging infrastructure, which gives way to the anxiety of running out of juice. Now though, the situation is on the trend of getting better, this charging solution integrated with solar rooftop is doing its bit to add to it. Solar panels and electric vehicles are the perfect match that is certainly going to play a key role in the energy systems of the next 25 years  

  • Intelligent vehicles will revolutionize our commute experience in the future and the Ather vehicle stands at the cusp of this exciting reality. Ather 450 and Ather 340 are one of the first fully indigenous and high quality electric scooters. The vehicle is powered by a brushless DC motor (BLDC) and uses a battery pack and battery management system (BMS) designed by the company. BMS and a range prediction algorithm helps predict the range accurately.

  • Traction batteries for electric vehicles, which run on voltages of several hundred volts, must be well protected. Electrical components are packed into a thin-walled yet stable metal housing. Housings of this kind are equipped with at least one pressure compensation valve mostly in the form of microporous film. A second valve is a safety measure: It only opens if damage to one or several battery cells results from a malfunction, and the buildup of gases has to be released. A smart pressure compensation element, the "DIAvent", combines both functions into a single component.

  • Due to the growing energy density of battery systems in Electric Vehicle, the developers of lithium ion batteries must satisfy ever higher safety requirements. It is especially crucial to keep a single damaged cell from overheating the entire battery module. The goal is greater range without the battery growing in size and weight. If neighboring healthy cells also heat up due to the heat buildup, a chain reaction can result that, in the worst case, could lead the entire battery system to explode.
