Disadvantages of Energy Management in Electric Fleets
While energy management in electric fleets has many benefits, there are also drawbacks and difficulties that fleet managers may run across. To successfully handle and eliminate these potential downsides, it is crucial to be aware of them. The following are some drawbacks:
1. Upfront Costs:
Investing in an energy management system and switching to electric vehicles might be expensive upfront because you have to buy the cars, set up the charging stations, and integrate the software. Some fleet operators may find these expenditures prohibitive, however, they are frequently made up for in the long run by savings.
2. Limited range and inadequate infrastructure for charging
- Range Anxiety: Drivers of electric vehicles may experience anxiety because they worry about running out of battery power while driving because their range is often less than that of conventional automobiles.
- Charging Infrastructure Gaps: It may be difficult to provide fleet vehicles with convenient and timely charging in some areas due to a limited or uneven distribution of charging infrastructure
3. Charging Time:
Refueling a conventional vehicle with gasoline or diesel can take much less time than charging an electric vehicle. The productivity of the fleet may be impacted by this downtime, particularly if cars must be charged throughout the working day.
4. Battery Degradation:
EV batteries can suffer from battery degradation over time, which lowers their capacity and range. To minimize this problem, effective battery management is crucial, but it could also be more expensive and involve more maintenance.
5. Variability in Energy Costs:
Energy costs might vary based on location and time of use, despite the fact that electricity is often less expensive than gasoline or fuel. To save energy expenditures, fleet managers must carefully control where and when to charge their vehicles.
6. Limited Vehicle Options:
The types of activities that can be electrified may be limited due to the lack of electric vehicle models that are suitable for particular fleet needs (such as heavy-duty trucks or specialty vehicles).
