Abstract
The article offers innovative circuit engineering solutions in the field of electric vehicles. The existing electrical and functional circuits of electric cars imply the presence of expensive electronic components, both in the control unit and in the wireless charging unit. An analysis of existing low- and medium-weight electric cars suggests that existing electronic circuits can be upgraded by replacing expensive elements with more affordable electronic components. In particular, it is proposed to introduce the STM32 microcontroller into the control and charging system of electric cars, which is actively used in technical projects of small and medium complexity. It is also acceptable to control a low-mass electric car using KYL-300L radio modules operating in the megahertz range. The electrical structural schemes proposed in the study will make it possible to implement simplified circuit design solutions for small and medium-weight electric cars. In the future, the authors plan to create a mock-up of a small electric car based on the proposed schemes.
