Electric vehicles are loved by consumers for their environmental friendliness and convenience. The battery and the motor are the most important parts, so here is some basic knowledge of electric vehicle batteries and motors from Xupai.

The electric vehicle battery:

The vast majority of electric vehicles today use lead-acid batteries, because lead-acid batteries are low in cost and offer great value for money. In 1859, the French scientist Planté invented a battery with lead electrodes. The unique feature of this battery is that after some time of use, when its voltage drops, a reverse current can be passed through it to bring the voltage back up. Because this kind of battery can be recharged and reused again and again, it is called a lead-acid rechargeable battery. In recent years, some electric vehicles have also adopted lithium batteries, which are not discussed in detail here.

The electric vehicle motor:

Electric vehicle motors come in different forms depending on their working environment and usage frequency, and different forms have different characteristics. Electric vehicle motors commonly use permanent magnet DC motors. A permanent magnet motor means the motor is excited by permanent magnets rather than excitation coils. This saves the energy an excitation coil would consume in operation and raises the electromechanical conversion efficiency, which for an electric vehicle running on limited onboard energy lowers the operating current and extends the driving range. By energization form, electric vehicle motors fall into two broad categories, brushed motors and brushless motors; by the mechanical structure of the assembly, they are generally divided into geared types (the motor spins fast and needs gear reduction) and gearless types (the torque output goes through no reduction at all). An electric motor is a rotating machine that converts electrical energy into mechanical energy, mainly including electromagnetic windings or distributed stator windings that produce a magnetic field, and a rotating armature or rotor.

The battery and motor of an electric vehicle are like the brain and the heart of a human being, and their importance goes without saying. After reading the above, we believe you now have a basic understanding of electric vehicle batteries and motors.
