Fleet electrification management

Abstract

Techniques are described herein for fleet electrification management. A method includes determining a composition of electric vehicles (EVs) to replace at least a portion of non-electric vehicles in a vehicle fleet while satisfying travel requirements of the vehicle fleet. The method includes estimating an energy demand of the composition of EVs. The method includes determining an electric vehicle supply equipment (EVSE) charging infrastructure to meet the estimated energy demand. The method includes providing one or more recommendations including at least one of: a fleet electrification recommendation for transitioning the vehicle fleet into the composition of EVs, or a charging infrastructure recommendation for implementing the EVSE charging infrastructure.

         2 . The method of  claim 1 , wherein determining the composition of EVs is based on at least one of:
 a current composition of the vehicle fleet;   minimizing a total cost of ownership for the vehicle fleet;   minimizing a total cost of charging for the vehicle fleet; or   an electrification planning time horizon.   
     
     
         3 . The method of  claim 1 , wherein the travel requirements of the vehicle fleet are based on at least one of:
 an average distance traveled for a defined period;   a maximum distance travel for a defined period;   vehicle operation times;   vehicle shift information; or   vehicle dwell times.   
     
     
         4 . The method of  claim 1 , wherein estimating the energy demand of the composition of EVs is based on a peak period of energy demand, which is estimated based on a quantity of EVs in the composition of EVs and their charging demand during a practical charging window in which the quantity of EVs are available to be charged. 
     
     
         5 . The method of  claim 1 , wherein the EVSE charging infrastructure is for multiple locations, and wherein the one or more recommendations are based on at least one of: vehicle routes, power availability, and fleet strategies. 
     
     
         6 . The method of  claim 1 , wherein the one or more recommendations are based on at least one of:
 energy storage systems (ESSs);   renewable energy resources (RERs);   energy price changes; or   energy load balancing.   
     
     
         7 . The method of  claim 1 , wherein the charging infrastructure recommendation includes a plurality of alternative charging configurations to meet the estimated energy demand. 
     
     
         8 . The method of  claim 1 , wherein the charging infrastructure recommendation includes a number and configuration of EVSE to be installed over a time horizon. 
     
     
         9 . The method of  claim 1 , wherein the one or more recommendations further include a recommended schedule for charging the vehicle fleet. 
     
     
         10 . The method of  claim 1 , wherein the one or more recommendations further include social or economic cost savings and benefits. 
     
     
         11 . A system comprising:
 one or more processors;   one or more storage devices operatively coupled to the processor;   instructions, stored on the one or more storage devices, which, when executed by the one or more processors, cause:
 determining a composition of electric vehicles (EVs) to replace at least a portion of non-electric vehicles in a vehicle fleet while satisfying travel requirements of the vehicle fleet; 
 estimating an energy demand of the composition of EVs; 
 determining an electric vehicle supply equipment (EVSE) charging infrastructure to meet the estimated energy demand; and 
 providing one or more recommendations including at least one of: a fleet electrification recommendation for transitioning the vehicle fleet into the composition of EVs, or a charging infrastructure recommendation for implementing the EVSE charging infrastructure. 
   
     
     
         12 . The system of  claim 11 , wherein determining the composition of EVs is based on at least one of:
 a current composition of the vehicle fleet;   minimizing a total cost of ownership for the vehicle fleet;   minimizing a total cost of charging for the vehicle fleet; or   an electrification planning time horizon.   
     
     
         13 . The system of  claim 11 , wherein the travel requirements of the vehicle fleet are based on at least one of:
 an average distance traveled for a defined period;   a maximum distance travel for a defined period;   vehicle operation times;   vehicle shift information; or   vehicle dwell times.   
     
     
         14 . The system of  claim 11 , wherein estimating the energy demand of the composition of EVs is based on a peak period of energy demand, which is estimated based on a quantity of EVs in the composition of EVs and their charging demand during a practical charging window in which the quantity of EVs are available to be charged. 
     
     
         15 . The system of  claim 11 , wherein the EVSE charging infrastructure is for multiple locations, and wherein the one or more recommendations are based on at least one of: vehicle routes, power availability, and fleet strategies. 
     
     
         16 . The system of  claim 11 , wherein the one or more recommendations are based on at least one of:
