The key components of electric vehicle
Electric vehicles comprise the electric motor powered by the battery. The outstanding advantage is that they produce zero emissions and are environmentally friendly. They don't rely on fossil fuels and use sustainable energy to run. The main EV components AEAUTO manufactures are:
EV Motor
EV motor is a very important in EV Components. The motor is the power source of electric vehicles, and its performance directly affects the power performance and driving efficiency of electric vehicles. There are two main types of motors basically: DC motors and AC motors. DC motors have fast starting speed and a wide speed range, but they require frequent maintenance; AC motors are highly efficient, quiet, and have a long life.
Motor Controller
MCU plays a vital role in EV components. It is responsible for receiving instructions from VCU and accurately controlling the torque and speed output of the motor to drive the vehicle. The MCU's efficient conversion function converts the DC power of the power battery into the high-voltage AC power required to drive the motor. It also has fault diagnosis and storage capabilities to ensure the stable operation of the motor system.
Electric Battery
As an energy storage device for electric vehicles, the capacity and performance of batteries directly determine the range and safety of electric vehicles. Currently, there are two main types of batteries : lead-acid batteries and lithium batteries. Lead-acid batteries are cheap and stable, but they are heavy and have low energy density. Lithium batteries have the advantages of high energy density, light weight, and long life, but they are more expensive and less stable than lead-acid batteries.
VCU
As the "brain" of electric vehicles, VCU is responsible for the core control tasks of the entire vehicle. It accurately calculates the torque and other parameters required by the motor based on the driver's operations, such as the accelerator pedal position, gear shift instructions and brake pedal force, combined with the battery status, to ensure that the electric vehicle runs smoothly. At the same time, VCU also has energy management functions, which achieves efficient energy utilization by optimizing driving charging and braking energy recovery, and works in conjunction with the intelligent body system to ensure instant response and safety of driving.
Power Inverter
It converts the DC power from the battery into AC power. It also converts the AC current generated during regenerative braking into DC current. This is further used to charge the battery. The inverter can change the speed.
EV Charging system
It includes charging interface, charging controller, charger and other equipment, supporting slow and fast charging. AEAUTO EV chargers consist of DC ev charger and AC ev charger together.
Braking system
It includes brake pads, brake discs, etc., responsible for deceleration or stopping. It adopts electric braking to ensure safety performance.
High-voltage system
It includes high-voltage cables, connectors and protective devices to ensure the safety of power transmission. High-voltage wiring harnesses are very critical and must meet the requirements of electromagnetic compatibility regulations. Therefore, methods such as glue injection and shielding wire wrapping are used on the surface of high-voltage wiring harnesses to reduce electromagnetic interference. Fuses are divided into two types: AC and DC. The fuses used in electric vehicles are related to the current type. DC systems use DC fuses, and AC systems use AC fuses.
Thermal management system
The thermal management system of electric vehicles can be divided into battery system thermal management, air-conditioning system thermal management and motor and electronic control system thermal management; the battery system thermal management and air-conditioning system thermal management have two major functions: cooling and heating, while the motor and electronic control system thermal management is mainly cooling. It controls environmental parameters such as temperature and humidity of the vehicle to ensure the normal operation and service life of components.
These AEAUTO EV components work together to enable electric vehicles to operate efficiently and safely while also meeting environmental protection and energy-saving requirements.
