This blog post will discuss the digital and software technologies involved in the wireless charging systems in EVs.

Wireless charging systems comprise a set of transmitters and receivers, In these systems, typically AC supply is converted into high frequency alternating current and this high frequency AC is supplied to transmitter coil. This creates an alternating magnetic field across the receiver coil and causes the production of AC power output in receiver coil.

The AC current at the receiver end is then rectified to DC and fed to the battery through Battery Management System (BMS).

Digital Opportunities in Electric Vehicles – EVIT



  • Charging software that can enable wireless inter-vehicle charging and detect other vehicles that are going to run dry.
  • Charging robots that can provide charging without human intervention at parking lots, malls, and public places.
  • Software stacks and solutions for V2G technology that can improve efficiency while reducing the digital footprint. 
  • Software to monitor, maintain, predict and alert the personnel about load and grid balancing and also to let customers know about different power tariffs at different times of the day. 
  • Softwares to maintain, monitor, and control the amount/quality of power flow into the battery.

Let us look at some of the software and digital solutions that can be used in wireless charging systems for more efficient performance:

  • Apple’s new wireless charging ecosystem- A drawing accompanying the patent, titled “Inductive charging between electronic devices,” shows a MacBook charging an iPhone and Apple Watch at the same time. The MacBook achieves this by embedding charging coils underneath the trackpad and inside the lid so devices can be charged while the MacBook is either open or closed. The patent indicates that reversible charging will, for instance, allow an iPhone to either charge or be charged by a MacBook. The software could be utilized to determine which device is closer to battery exhaustion and automatically select that device for charging. This can be adopted and tailored according to the EV echo system where an ideal EV can sense the vehicle in dry out condition nearby and can transfer some power to it. This adoption can reduce the range anxiety and can be a bigger positive if there is no charging station nearby.
  • VW autonomous charging robot – VW has unveiled an actual working prototype of an autonomous charging robot for electric cars. The charging robot—started via an app or Car-to-X communication—operates totally autonomously. It independently steers to the vehicle to be charged and communicates with it: from opening the charging socket flap to connecting the plug and decoupling it. The entire charging process takes place without any human involvement whatsoever. To charge several vehicles at the same time, the mobile robot moves a mobile energy storage unit to the vehicle, connects it, and then uses this energy storage unit to charge the vehicle and repeats the process to charge other vehicles. Once the vehicle is fully charged, the robot independently collects the mobile energy storage unit and takes it back to the central charging station. they are equipped with 25 kWh battery packs each and they can charge a vehicle at 50 kW through DC fast-charging. The charging robot can move several battery wagons at the same time.
  • Awesense Digital Energy Platform for V2G – Awesense has been selected as a partner in a project involving the integration of Electric Vehicle charging stations (EVSE), Energy Storage Systems (ESS), and a microgrid controller, to analyze, manage and optimize the use of these technologies in a pilot program focused on building resiliency and reducing costs. The goal of the project is to provide a next-generation DERMS solution with unparalleled situational awareness and the ability to make decisions and control DER based on real-time grid conditions. The joint solution, developed between Awesense and Doosan GridTech will integrate Awesense’s Digital Energy platform, and Doosan’s DERMS software, DERO. The microgrid will include Vehicle-to-Grid-enabled EVSE, capable of discharging stored energy from connected EVs back into the grid and provide support during an outage or other events. Located within and outside the microgrid, are utility-owned large scale ESS devices, controllable by the DERMS solution. These devices will also be leveraged to optimize for a set of pre-defined use-case scenarios, from congestion management to peak load reduction and voltage support.
