Our Services

We build the architecture of wireless charging solutions, ensuring optimal energy efficiency. Our team designs circuits and PCB layouts to minimise energy loss, considering factors like resonant frequency tuning and magnetic field optimisation.

We build electric vehicle charging software to establish communication between the charging station and the receiving device. Our team uses protocols that enable adaptive charging and help adjust charging parameters.

We integrate Open Charge Point Protocol (OCPP) into our wireless charging solutions to enable data exchange and real-time status monitoring. This ensures interoperability with charging networks and EV charging station software.

Our mechanical engineers design charging pads with precision alignment mechanisms and electromagnetic shielding to minimise interference. Our durable enclosures protect sensitive components from environmental factors.

We design inductive charging stations, creating proper alignment features for user-friendly device placement and enabling intuitive usage.

Our Case Studies on Inductive Charging

OCPP implementation

Working with our client, an American EV technology company, we integrated the OCPP into the charging stations software. This enabled the device's compatibility with a range of CSMS. Through refactoring and bug fixing in the existing firmware, we enhanced performance and ease of maintenance.

Our client reduced costs, achieved a competitive edge and expanded their customer base by managing charging stations from different manufacturers.

Switch box control software

We engineered switch box control software that redistributes electricity for induction charging stations of a European developer.

In this project, we developed switching detector driver for relay status signals, and PP signal monitoring drivers, as well as implemented the following features:

  • processing of CAN messages,
  • sending a status message,
  • switching of power and alarm relays,
  • sleep mode activation and exit.

What advantages does wireless charging bring, and which companies already operate in this market segment?


We address this subject in our article about inductive chargers for EVs. Let's delve deeper into the technology with new engineering solutions from Promwad and other international companies.


Can EV wireless charging work with different power levels and battery capacities?


EV wireless charging technology is designed to serve various power levels and battery capacities. The power electronics dynamically adjust the energy transfer rate, ensuring compatibility with various battery specifications. This adaptability provides efficient and safe charging without compromising or overloading the battery's health.


How is inductive charging contributing to the widespread adoption of EVs?


Inductive charging simplifies the charging process, making it more user-friendly and convenient for electric vehicle owners. By eliminating the need for physical connections, drivers can effortlessly park over a charging pad, encouraging a broader demographic to consider electric vehicles. This ease of use, combined with a streamlined charging experience, helps accelerate the adoption of EVs.


What role does EV charging station software play in optimising power distribution and dynamic load management?


EV charging station software plays a critical role in monitoring real-time energy demand, usage patterns, and dynamic load management. Its goal is to distribute power among connected vehicles, prevent grid overloads and ensure efficient energy allocation. By dynamically adjusting power delivery based on demand, the software optimises performance while maintaining grid stability.


How does EV charging management software enhance the overall experience for electric vehicle owners?


EV charging management software provides real-time visibility into available charging stations, so users can locate and reserve them conveniently. Integrated payment systems simplify transactions, while remote monitoring offers flexibility. Additionally, smart algorithms consider energy rates and battery health, optimising charging times and ensuring a cost-effective experience.
