As I detailed in a previous article on the challenges of migrating to an electric vehicle fleet, many companies are now migrating to electrically powered vehicle fleets for their operations. Whilst many may concentrate on having sufficient vehicles and respective achievable range based on the calculated amount of deliveries and suchlike there remains a far more important factor to consider:
“How can I make sure all of my new vehicles are charged ready for the next day’s operations?” After all, it’s no use having all the vehicles and capacity if you can’t charge them up on time!
A Range of Calculations
Number of Charging Points
Capacity of Charging Points
- The connected vehicle cannot operate at that charge level due to temperature constraints, battery charge level, or simply because its maximum capacity is below that of the charger.
- The charging point itself may not be able to pull enough power from the local grid to supply its maximum output - particularly if it’s sharing a local connection with a number of other chargers that are also demanding a large amount of power.
- Charging points can develop faults that affect their operation or take them out of service completely - this needs to be considered in any charging plan.
Electrical Capacity Restrictions
- Increased capacity provision
May be expensive to construct and require planning permission
- Dependent on electricity supplier and their own local grid capacity (they simply may not be able to provide that level of power).
- Staggered charging profiles
- Implemented via a provision that not all vehicles are charged at the same time and an algorithmic way is found of charging to the required minimum range levels, whilst simultaneously, not exceeding a set maximum power demand from the aggregated charging point demand.
