    Battery Degradation / Extended Charge

    No recording. Seems I would have to put the car on a lift and get some recording equipment. Or I would hang out the door and hold the cell phone under while moving (sounds scary). Any info on how to get a recording of the motor noise would be appreciated. Mark

    Battery Degradation / Extended Charge

    Thanks all for the info on battery degradation. This my understanding of the several responses: I shouldn't complain that my 7 year old 60K mile EV still gets 65-75 GOM (& actual) range. I rarely drive more than 25 miles a day, so who cares what the GOM says. Like taking my blood pressure, I...

    Battery Degradation / Extended Charge

    Thanks for your reply Al. Great reply to my last post. One of the frustrating things about this board is that you can ask a specific question, and you get lots of answers that don't address or answer the question. My original post ask this question: "It seems odd that the battery would degrade...

    Battery Degradation / Extended Charge

    Alflash - Great info. 2013 Year Vin 2T3YL4DV5DW001654 I've learned the GOM is just that...80+ mph doesn't get me a lot of range. Thanks again for your help. Mark

    Battery Degradation / Extended Charge

    Didn't see a reply button, so.. Unhooked the battery, got 123 mile range. Thanks Alflash - I'll do the battery disconnect as you described in the next day or two and get back to you with the results. Both times when the car came back from the dealer, the range was 127 & 129 miles. Same when...

    Battery Degradation / Extended Charge

    Alflash - Thanks for your reply. It appears your file shows information from the Toyota Techstream diagnostics. Early on, the car was taken to Oxnard Toyota twice. Both times a "health check" was done. I was told there was no other diagnostic available for the car, there was no way to measure...

    Battery Degradation / Extended Charge

    Shortly after I purchased my RAV4 2/17, I discovered that my GOM range was 70 miles, with regular or extended charge. Members here said that that was normal, as the battery had degraded that much in three years & extended range would no add any range. Now, almost four years later, my average GOM...

    Is the "Tony test" the only way to measure battery?

    Thanks for the info. Any ideas how to deal with a dealer (Toyota Oxnard) who claims there is no Techstream software, and only provides Toyota "health check" diagnostics? Thanks, Mark

    Is the "Tony test" the only way to measure battery?

    Wow...so if I do the "Tony test" and my battery only has 35% of original capacity, the dealer will replace the battery (under California state warranty) on my say so, lol. Come on now, are you really saying the dealer has no way to test the capacity of the traction battery to see if it should...

    Is the "Tony test" the only way to measure battery?

    Can someone verify that there is no way for a Toyota dealer to test the capacity/degradation of the traction battery. I have been told this by two Toyota EV service departments/techs. Sounds crazy. Thanks, Mark

    Confused about Battery Degradation

    When I got my RAV4 EV two years ago it would charge to the same range (~85 miles) using both regular and extended mode. On this forum it was explained to me that was proper operation: once the battery has degraded to 85% capacity it will be charged to full capacity with both charge modes , and...

    Extended Charge not working

    Thanks for the clarification. I'm surprised that with 15% or more degradation the battery is being charge to 100% capacity, or essentially an Extended charge. My owners manual says this can/will shorten the life of the battery, as opposed to an 85% capacity charge. Any way to keep from cooking...

    Extended Charge not working

    I'm still confused. Using the tgreene's numbers of 41.8 and 35 kWh for normal and extended charge. If the battery is 50% degraded, then an normal charge would be 17.5 kWh, an extended charge 20.6 kWh. And it would take 30min-hour to add those 4 kWh. Other responses imply that Only the...

    Extended Charge not working

    Thanks for the info...the next step seems to do the "Tony Test" for some numbers. I don't understand the "battery degradation" explanation. My understanding is that a "regular" 70% charge is used to help reduce battery degradation. Meaning that if the battery has degraded from 42 to 21 kWh, 70%...

    Extended Charge not working

    Hello all. My 2013 Rav4 EV does not do an Extended charge. I get the same range (~65 miles) whether I use Extended or Regular charging. If I do a Regular charge, then select Extended charge, the charger clicks off after a few minutes with a additional mile of range. It seems the charger is...
