Electric vehicles (EVs) have gained popularity in recent years as a cleaner and more sustainable alternative to traditional internal combustion engine (ICE) vehicles. With advancements in battery technology and charging infrastructure, EVs are becoming more accessible to consumers. While they offer numerous benefits, such as reduced greenhouse gas emissions and lower operational costs, it’s essential to recognize that EVs also have unique maintenance requirements. One aspect that often gets overlooked is the need for increased suspension and chassis maintenance in electric vehicles.

EVS SUSPENSION AND CHASSIS

In our previous blog “Increasing weight of EVs and their consequences?” we menioned increasing strain on chassis components. In this blog we will go into more depth about the reasons why more maintenance for suspension and chassis is needed.

  1. Heavy Battery Packs: The most significant factor leading to increased suspension and chassis maintenance in EVs is the weight of the battery pack. These packs are massive and, in many cases, distributed throughout the vehicle’s undercarriage. Over time, this extra weight can lead to the sagging of suspension components, such as springs and shocks, affecting ride comfort and handling. Regular inspection and maintenance are crucial to ensure that the suspension system can handle this additional load.
  2. Torque-Induced Stress: As mentioned earlier, electric vehicles generate instant torque, which can lead to a higher level of stress on the suspension and chassis components. This can cause components like control arms, bushings, and ball joints to wear out faster than in traditional vehicles. Regular inspections are necessary to identify and address issues promptly.
  3. Regenerative Braking Wear: While regenerative braking is an efficient way to recharge the battery, it also results in increased stress on the brake system, suspension, and chassis components. The constant shifting between regenerative and friction braking can lead to faster wear on suspension and chassis components. Regular brake and suspension inspections can help mitigate these issues

Electric vehicles represent a promising future for cleaner, more sustainable transportation. However, it’s important to recognize that they have unique maintenance requirements, particularly when it comes to their suspension and chassis systems. The extra weight from the battery pack, the effects of instant torque, and the wear from regenerative braking all contribute to the need for more frequent suspension and chassis maintenance in EVs.
