3. Extended warranties – especially battery warranties (5-8 or up to 10 years)
Longer warranties would add comfort.
One fleet suggested a warranty period of 8 years for Light Duty and 10 years for Heavy Duty.
It would also be nice to have a secondary market for the battery so the fleet doesn’t pay for the full cost of the battery upfront. But since the cost of the warranty is built into the price of the vehicle, will extended warranties increase price?
OR: battery leasing (not swapping) options to reduce capital cost, liability
4. Wiring harnesses/wiring integrity, Need better battery management systems with better than pack level management
The repair and module replacement for one utility’s fleet of light duty EV’s is less than 1% over 13 years of operation.
But the heavy duty vehicles have experienced many issues, including problems with wiring integrity/ wiring harnesses, lack of secure weatherproof wiring, the BMS is not where it should be, and the pack level battery control is not sufficient.
Many fleets have discovered that there are limits to where they can park their trucks due to infrastructure costs and location. It takes planning and becomes especially expensive when it is necessary to run out conduits to new parking places that are not near existing buildings.
It can cost $6-8 thousand dollars to install EVSE without even breaking concrete.
Transparency in Purchasing Decisions
Vendors need to be more “up front” when selling trucks about what the options and costs are for recharging.
The cost of installation and associated infrastructure needs to be explained better with cost estimates and power requirements.
This is a big issue that determines the total cost of ownership. Fleets need to know all costs at the time of purchase so they can include this in the capital cost. Otherwise, it hits fleet expenses.
