In electric cars, two electrical systems are used – high -voltage and low -voltage. The first (at the atom of it is 400-voltovaya) is responsible for the engine that controls electronics and the traction battery. Low -voltage, working 12 volts, includes all the on -board electronics: screens, telematics, driver assistance systems and so on. The latter is made for the atom from scratch, since none of the ready -made solutions to the domestic electric car came up.
The fact is that the atom has its own platform and a lot of “chips”. This is a screen in the steering wheel, automatic swing doors, a projection display with augmented reality (AR-HUD) and much more. The development of low -voltage architecture requires time and resources, but there are obvious advantages: it is easy to optimize, adding new functions for the current project and changing for the following.
Low -voltage and high -voltage atom systems

At the first stage, the developers determine what kind of functions the electronics should perform, and prescribe the relevant requirements for blocks and software. The architecture of the system is decentralized – it does not have a domain or central controller: there is no dependence on one block, which increases reliability. In addition, you can separately “awaken” the necessary blocks, not launching the entire system as a whole. It protects electricity – and therefore a margin of move.
The second stage is the design of the network topology. The systems of the system communicate with each other and with other components of the car through wired connections selected for different tasks. Both common types like CAN and designed specifically for an atom are used. By the way, there are few ready -made solutions: about 80 percent of the components for electronics have to be adjusted for the project one way or another.
The third and last stage is a validation that allows you to evaluate the performance and “maturity” of architecture. First, individual components are checked, then the systems and, finally, tests are carried out on prototypes. Electronics are tested in the atom of the atom in the Chinese city of Nankin, in St. Petersburg and in Moscow.

For tests, the so-called Labcar was built in the metropolitan laboratory-a metal layout. On it, working electronic components are located in the same way as on a car, but more clearly – not hidden in upholstery and under body panels. You can, for example, check the operation of the steering wheel and seats, headlights and backlight, immediately receiving data from sensors.

The atom is also promised its digital marketplace and a unique ID atom identifier, under which it will be possible to log in by taking the car in car sharing. A mobile application is also being prepared, and it will be possible to control from a smartphone almost all the functions of an electric car. They plan to launch mass production in Moscow in 2025.
