Electric Vehicle Rebates ΒΆ
One of the policies that SANDAG planners would like to test for the 2025 Regional Plan is providing rebates for low- and middle-income households to purchase electric vehicles. One of the variables in the vehicle type choice model is the new purchase price for a vehicle of a given age, body type, and fuel type. The way the EV rebate is implemented in ABM3 is by deducting the appropriate rebate value for plugin and battery vehicles if a household meets the criteria (based on percentage of the federal poverty level). To configure the rebate values and poverty level thresholds, new constants were added to the common/constants.yaml configuration file. Two describe income group cutoffs and need to be updated in src\asim\configs\common\constants.yaml and four specify rebate values for various income groups and need to be edited for the scenario’s given year in input\parametersByYears.csv.
| Constant | parametersByYears field | Description |
|---|---|---|
| LowIncomeEVRebateCutoff | N/A | % of poverty limit below which a household is considered low-income for the purposes of EV rebates |
| MedIncomeEVRebateCutoff | N/A | % of poverty limit below which a non low-income household is considered medium-income for the purposes of EV rebates |
| LowIncomeBEVRebate | ev.rebate.lowinc.bev | Rebate value for low-income households buying battery electric vehicles |
| LowIncomePEVRebate | ev.rebate.lowinc.pev | Rebate value for low-income households buying plugin electric vehicles |
| MedIncomeBEVRebate | ev.rebate.medinc.bev | Rebate value for medium-income households buying battery electric vehicles |
| MedIncomePEVRebate | ev.rebate.medinc.pev | Rebate value for medium-income households buying plugin electric vehicles |
The constants fit into the policy as follows:
| Fuel Type | LowIncomeEVRebateCutoff < Household Poverty Level <= MedIncomeEVRebateCutoff |
Household Poverty Level <= LowIncomeEVRebateCutoff |
|---|---|---|
| BEV | MedIncomeBEVRebate |
LowIncomeBEVRebate |
| PEV | MedIncomePEVRebate |
LowIncomePEVRebate |
For example, if the following policy were to be tested…
| Fuel Type | Rebate amount for households within 300-400% of Federal Poverty Limit | Rebate amount for households at 300% Federal Poverty Limit or lower |
|---|---|---|
| BEV | $2,000 | $6,750 |
| PEV | $1,000 | $3,375 |
…then the constants would need to be set as follows:
LowIncomeEVRebateCutoff: 3
MedIncomeEVRebateCutoff: 4
LowIncomeBEVRebate: 6750
LowIncomePEVRebate: 3375
MedIncomeBEVRebate: 2000
MedIncomePEVRebate: 1000
