NTK reveals 5 curiosities about the electrical components of vehicles

Marca ainda compartilha os principais avanços tecnológicos que têm acontecido nesse sistema

São Paulo, maio de 2024 – The NKT, Niterra brand Japanese multinational specialist in components for ignition systems and automotive products, shares five curiosities about vehicle electrical systems that most people are unaware of. These notes offer a broader picture for vehicle owners about their operation and their importance in the maintenance and operation of the engine.

1. Battery diagnostics as a priority: currently, The first diagnostic item in a vehicle electronics system is the battery status. Many failures in electronic systems can be attributed to a battery in poor condition.
2. Complex battery configurations: Some high-end vehicles have more than one battery, one being the main one and the other the auxiliary for electronic systems. This configuration reflects the increasing demand for energy in modern vehicles.
3. Battery parameters beyond voltage and capacity: in the past, A battery was defined only by its voltage and ability to accumulate charge. currently, It is essential to consider the cold starting current (CCA) and the type of material to ensure proper functioning, The most modern materials will impact the discharge capacity (Cycles), types of technology the vehicle has and recharge time.
4. Risks of Using Auxiliary Battery for Starting: Starting a car with the auxiliary battery, in cases where he gets a dead battery, may result in significant damage to electronic modules, if the procedure is performed incorrectly.
5. Impact of low battery charge on electronic modules: Vehicles with low battery charge can generate various errors in different electronic systems (Modules) because of the voltage drop. After the cargo is regularized, It is important to check the entire electronic system to assess its correct functioning and erase the failures generated. In this way, Avoids diagnostic errors generated by defect codes stored in system memory.

A vehicle's electrical system is made up of different systems: The Powertrain (Propulsion engine, streaming, and so on.), The chassis (structure, suspension, Brakes), The Body –body (Climate, audio, airbag) it's the Network – Data Network (Communication between systems). This division allows the electrical part to act as a means of contact between the systems, providing power and transmitting commands and information (data). The generation of DTC defect codes (Diagnostic Trouble Codes), that mechanics are used to checking with automotive scanner equipment, are based on this systems division.

The aforementioned systems have experienced significant technological advancements recently. "This evolution aims to prioritize safety, energy efficiency and simplify diagnostics and maintenance. Notable changes in the power supply, in which The battery takes center stage and the alternator provides power only when needed, represent a new paradigm in the automotive industry", afirma Hiromori Mori, Technical Assistance Consultant at Niterra do Brasil.

Sensors are usually integrated into the vehicle's electrical system. These crucial elements are connected to vehicle systems via electrical cable assemblies, known as wiring harnesses. Any failure of this equipment can result in substantial interference with the electrical operation of the vehicle. Many sensors have a power supply (Reference voltage) and send the information through the wiring harness. Failures in the electrical systems and battery directly interfere with the correct operation of the vehicle, sendo a sua avaliação um item fundamental em um reparo automotivo. A NTK se destaca como fornecedora de nove diferentes sensores como sensores de oxigênio, Fuel level, Coolant temperature, ABS, rotation, speed, butterfly position (TPS), MAP (absolute pressure) and oil pressure switch.
