Introduction With the rapid development of the electric vehicle industry, the electric drive system sector has also made significant progress. Product technology continues to improve, the scale of industrial development is expanding, and new materials and processes are emerging. The trend of integration is becoming more evident. Due to the complexity of electric vehicle driving […]
1. Electric Vehicle Drive Motors 1.1 DC Motors Early electric vehicles (EV's) often used DC motors due to their simple control mechanisms and low cost. The most common types include separately excited DC motors and series-wound DC motors. Egter, the presence of a commutator and brushes leads to mechanical wear, requiring regular maintenance. These components […]
Preface In recent years, new energy vehicles have been booming under the guidance of national policies. Currently, most electric commercial vehicles, such as pure electric buses, pure electric logistics vehicles, and pure electric road sweepers, adopt pneumatic braking systems and pneumatic door control systems. The electric air compressor system (hereinafter referred to as the electric […]
Over the past few years, the growing popularity of electric vehicles (EV's) has brought attention to some of their unique features and design choices. One topic that often sparks curiosity is why EVs generally do not include spare tires. This article explores the reasoning behind this design decision, examines alternative solutions provided by manufacturers, and […]
The emergence and development of electric vehicles (EV's) represent a significant technological leap, positioning them as a cornerstone of future transportation. EVs are not just an alternative to traditional internal combustion engine (ICE) vehicles; they embody a transformative approach to mobility. But why are EVs so widely praised and increasingly popular? Below, we address key […]
Elektriese voertuie (EV's) possess unique technologies and advantages that enable them to actively contribute to grid frequency regulation. Their energy storage systems, typically based on high-energy-density lithium-ion batteries, can efficiently store and release energy over extended periods. Equipped with advanced electric drive systems, EVs convert stored electrical energy into mechanical energy with exceptional efficiency to […]
Elektriese voertuie (EV's) have become one of the most promising innovations in the transportation industry in recent years. Increasing numbers of traditional automakers, as well as companies from outside the automotive sector, are venturing into EV production. But why is there such a strong desire to produce EVs? This article delves into the key reasons […]
Elektriese voertuie (EV's) require less maintenance primarily due to their simpler construction, fewer components, ease of maintenance, and reduced likelihood of common mechanical issues. Unlike traditional internal combustion engine (ICE) vehicles, EVs eliminate many complex components such as crankshafts, connecting rods, pistons, and fuel injection systems. This significantly reduces the chance of engine-related failures. Die […]
There are numerous reasons why electric vehicles experience “false battery” in the second half of their range, with insufficient battery capacity being the most prominent one. The battery capacity of an electric vehicle determines its driving range. When the battery capacity is inadequate, the electric vehicle may encounter energy shortages during driving. Vraag 1: Why […]
The slow charging speed of battery – electric vehicles (BEVs) is primarily attributed to the charging characteristics of the batteries and the limitations of charging equipment. Constraints in battery technology result in relatively sluggish charging rates. Batteries are the key components for storing energy in BEVs, and most of the batteries currently used on the […]
