Wherever possible, I tried to credit the initial author/posters in _credits.txt files which display inline on the directory listings. If you see a file that is not credited and know who to credit, or you would like a file taken down, please let me know.
As long as possible! I have pre-funded the domain and hosting for at least the next 10 years. However, none of the links currently on the site should be considered permalinks. I intend to host the content indefinitely, but cannot (at this time) guarantee the URL structure will remain the same.

There are two semi-active communities
Alexandra Paul (aep at alexandrapaul.com) and Alex Girniak (oleksii.girniak at gmail.com) maintain a list of known owners and their contact information.
There are several independent skunkworks projects in various stages of converting the car to lithium. As you might imagine, this car tends to attract nerds, and nerds like to tinker.
If you are comfortable with the fundamentals of EV/battery technology and/or have done EV conversions in the past, this car makes a great project. If you're thinking you'll just get a pack from a wrecked modern EV and drop it in, it's unfortunately not that easy.
I don't know of any "off-the-shelf" kits or services available at this time, but I will update if any become available.
A shop in Salinas called Trajectory EV developed a drop-in lithium conversion in 2023. They both sold DIY kits and performed the conversions themselves. They went out of business in late 2024 and briefly sold DIY kits under another brand. Despite the significant cost ($25+ K) several members of the community had the conversion done and report amazing results.
Lanny Thomason (southtownelanes at msn.com) has done conversions in
the past, I am not sure if he is still offering them [todo: verify]
It's complicated and extremely subjective. Obviously the rarity plays strongly in its favor, but the state of the battery packs (universally toast by now) swing it strongly the other direction.
The reality is that a non-op 90s Rav4 has almost no book value, so there is real risk that they are crushed for scrap or dismantled for parts.
If you are looking to sell your Rav, I recommend posting on the Facebook Group and Mailing List as well as traditional listing sites like eBay, Craigslist, FB marketplace, etc.
You can also reach out to webmaster at rav4ev.org and I will try to
connect you with anyone I know is looking.
All Gen1 RAV4 EVs were built at Toyota's Motomachi Plant in Aichi, Japan. It's website lists the cumulative production as 1,932 vehicles globally.
Toyota's website at one point said "1,484 vehicles were sold or leased in the U.S."
It is widely believed that 328 units were sold at the end of their leases, but I cannot find a definitive source for this.
The Gen1 RAV4 EV's traction motor and inverter produce coarse torque steps at very low RPM. When creeping or feathering the pedal, especially in reverse, those torque pulses transmit through the drivetrain and feel like cogging or a brief shudder. This is generally normal if it is mild, limited to very low speeds, consistent over time, and not accompanied by noises, vibration at higher speeds, or any fault codes.
You can reduce it by avoiding ultra-slow creeping. Let the car roll to about walking speed with a light, steady pedal, then increase throttle smoothly instead of hovering right at the edge of movement.
The Gen1 RAV4 EV traction battery uses 24 sealed NiMH modules, each ~12 V nominal, for a total pack voltage of ~288 V (24 × 12 V).
Each module contains 10 NiMH cells (~1.2 V each) in series, which is how Toyota/Panasonic achieve the 12 V-class rating. The system is specified entirely at the module level, not loose cells. The production modules are ~95 Ah, giving a nominal pack energy of ~27.4 kWh when new.
For service or replacement, treat every unit strictly as a 12 V NiMH module of matching construction and capacity—mixing different module types or voltage-classes will cause imbalance and charging faults.
To maximize longevity of the Gen1 RAV4 EV's NiMH traction pack, prioritize temperature control, avoiding deep discharge, and minimizing time spent at low SOC.
Keep it cool — High pack temperature is the dominant NiMH aging driver. Favor charging and parking in cooler conditions and avoid repeated full charges when the pack is already warm.
Avoid deep discharge — Don't routinely run to warning lights or "turtle." Recharge earlier to reduce stress on the lowest modules and prevent imbalance.
Don't let it sit empty — If you finish a trip at low SOC, recharge soon rather than leaving the pack near empty for extended periods.
100% is fine in moderate weather — Full charges are safe for this chemistry under normal temperatures.
Limit to ~90-95% in hot weather — In heat, stopping slightly short of full reduces thermal load and is gentler on the front modules, which run warmer and have less effective cooling.
Shallow, frequent charging is beneficial — Topping up at any SOC (including above 50%) supports balance and does not harm this pack design.
With these habits, real-world vehicles maintain strong capacity and low module resistance well past 70,000 miles. You can safely top up from partial SOC at any time; the key risks to avoid are high temperature and severe over-discharge, not charging above ~60%.
The Gen1 RAV4 EV's electric heater draws about 1.5 kW from the traction pack, so continuous use adds a large fixed load that can significantly cut driving range.
The most efficient steady-state cruising speed for a stock Gen1 RAV4 EV is ~30-35 mph on flat roads. Aero drag stays low in that range, giving the lowest Wh/mi.
Above ~40-45 mph, drag rises sharply and range drops. For maximum range or health checks, hold a steady 30-35 mph, keep HVAC minimal, and ensure proper tire pressure/alignment.
Occasional yellow-zone use is acceptable, but repeatedly driving deep into red or very low power before recharging can accelerate NiMH pack degradation and should be minimized.
"Snow Mode" on the Gen1 RAV4 EV is a simple driver-controlled power-limit switch that tells the inverter to cap output to ~30 kW instead of the normal ~50 kW. Reducing peak power lowers pack current, cuts voltage sag, and delays turtle mode—especially helpful on aging NiMH packs—while preserving normal drivability at moderate acceleration.
It's a low-voltage control-line modification (no HV pack access, no reprogramming). The switch feeds the inverter/ECU a reduced-power request.
