Electric vehicle energy saving mode

Why do electric vehicles need energy management?

An electric vehicle relies solely on stored electric energy to propel the vehicle and maintain comfortable driving conditions. This dependence signifies the need for good energy management predicated on optimization of the design and operation of the vehicle's energy system, namely energy storage and consumption systems.

Is energy-saving control strategy a hotspot in electric vehicle research?

As can be seen, energy-saving control strategy is one of the research hotspots in the field of electric vehicle. Despite the previous efforts, the dynamic time-varying information of traffic environment, such as the motion of the preceding vehicle, are not fully considered in these energy-saving control strategies.

Why is driving energy management important for EVs?

In the current situation, where the increase in the battery energy density has reached a bottleneck, driving energy management will be an effective means to further improve the driving range of EVs, and it will also be a valuable and crucial direction for further energy conservation in EVs.

What is the energy storage system in an electric vehicle?

The energy storage system is the most important component of the electric vehicle and has been so since its early pioneering days. This system can have various designs depending on the selected technology (battery packs, ultracapacitors, etc.).

Why do EVs need a motor?

For EVs, the application of the motor provides them with better control performance, more responsive and flexible torque response, and better dynamic performance, for example, than traditional vehicles with internal combustion engines.

How can decentralized drive EVs save energy?

Therefore, an effective energy-saving means for decentralized drive EVs is to use the additional yaw moment generated through traction torque distribution to reduce the power of cornering resistance, which can be achieved by torque vectoring.
