Understand electrical systems and batteries
Electrical systems are fundamental to the operation of modern vehicles. Batteries, control units, electric motors and other components supply and manage the energy needed for different vehicle functions.
12-volt battery
The 12-volt battery supplies energy for starting and for numerous vehicle electrical systems. Its capacity and condition directly affect the operation of the components that depend on it.
Charging systems
The charging system keeps the battery at the energy level needed while the vehicle operates. The alternator and other electrical components work together to supply energy and keep the battery charged.
Electrical systems in hybrid and electric vehicles
Hybrid and electric vehicles incorporate high-voltage systems that store and use energy for propulsion. These systems require specific components and safety measures different from those of conventional electrical systems.
Electronic energy management
Control units monitor and manage different vehicle electrical functions. Sensors and electronic modules allow energy supply to be controlled and numerous systems to be coordinated.
High-voltage batteries
High-voltage batteries store the energy used by electric motors in hybrid and electric vehicles. Their capacity, technology and management system affect vehicle performance and range.
Energy recovery systems
Some vehicles can recover part of the energy during deceleration and use it to recharge the battery. This technology helps improve powertrain energy efficiency.
How to choose according to your needs
When evaluating an electrical system, consider the vehicle type, battery technology, energy capacity, charging systems and maintenance needs.
Understand your vehicle’s electrical system
Knowing the main electrical components makes it easier to interpret vehicle specifications, understand their functions and assess the differences between energy systems.
