Most auto manufacturers warranty the battery for 8 years and there are even extended warranties available too.

Because the battery pack is under warranty for 8 years you aren’t likely going to be buying a new battery pack any time soon. Let’s pick a number though, say $15,000 to buy a new battery at current prices, and let’s say in the 9th year, you have to replace the battery. We know 3 things about lithium-ion and other evolving batteries types. Eight years down the road they will be;

i) lighter weight,

ii) have much greater power density,

iii) less expensive.

With the way battery technology is evolving, chances are very good that you will be able to get a battery for 1/3 the present cost and quite likely it will provide triple or greater range and your vehicle will be lighter weight, all providing further opportunities for savings.

Battery Acceptance / Receptivity Rates

Note to EV owners and soon-to-be owners:  Your Vehicle Acceptance Rate will determine what type of EV charging station you will choose to install at your home or business.  Depending on your vehicle’s needs, some stations will be ‘overkill’ and make no difference in the time it takes to charge your vehicle (note the yellow highlights in the chart below).  Other charging stations won’t be enough to charge overnight. SRP Electric will be pleased to assist you in this regard!

Battery Acceptance Examples

 A)    A Toyota Rav4 EV charging with an LCS-25 charging station with 240V:

Check the Vehicle Acceptance Rate versus the Charging Station Delivery Rate for the LCS-25.  Which is lower?  That will be your limiting factor.  Vehicle Acceptance Rate of the Toyota Rav4 EV is 9.6 kW.  The LCS-25 Delivery Rate is 4.8 kW.  Use 4.8 kW because it is the lower of the two numbers (this is the maximum power the charging station can deliver to the vehicle).
Divide the battery capacity by the lower number from above.  Divide 41.8 kWh by 4.8 kW from above.  The result is 8.71 hours to recharge the battery pack from empty to full.

B)     A Toyota Rav4 EV and a CS-50 charging station with 240V:
Check the Vehicle Acceptance Rate versus the Charging Station Delivery Rate for the CS-50.  Which is lower?  That will be your limiting factor.  Vehicle Acceptance Rate of the Toyota Rav4 is 9.6 kW.  The CS-50 Delivery Rate is 9.6 kW.  Use 9.6 kW because both are the same (it is both the maximum the vehicle will draw and the maximum power the charging station is capable of delivering).
Divide the battery capacity by the lowest number from above.  Divide 41.8 kWh by 9.6 kW from above.  The result is 4.35 hours from empty to full.
