My wife has a Chevy Bolt. Chevy installed an L2 charger in our garage. She has an L2 charging cable. Okay to use that to charge the 2024 Prius Prime I’m supposed to get in a month?
L2 charge cords are standardized and should work with any level 2 equipped plugin. Some of the charge cords have a real snug fit while others slide into the port without a hint of binding. The Prime comes with a cord also. So if there is already a charger it should be easy and inexpensive enough to add and outlet for the Primes cord on your bolt charger circuit. And if the bolt charger install has a 40 Amp breaker and the right gauge wire you might be able to charge the bolt and the prime at the same time.
Since you seem to be all in on ev’s, it is a good time to learn about charging. Chevy paid for a 50 amp breaker, wiring and outlet. If they mounted an evse, that’s a separate deal. If that is plugged in, be careful, the outlets are often sub standard and can overheat and catch fire. If it is hard wired, you’re good. If it is just the outlet, and you’re plugging the Chevy evse into it, that pulls 40 amp’s, so use caution again and feel the plug and outlet for heat. The prime evse may or may not fit the outlet type, idk. The prime pulls fewer amps than the bolt, so it’s not a problem
We got 2 level-2 (Juicebox Pro, back in 2017 when the company was still eMotorWerks) and have been using them ever since. Mine started with the Prius Prime and is now used with my bZ4X. My wife is still using the other with her Prius Prime.
@john1701a are both of your juiceboxs' on one circuit or each box have it's own circuit? And are the juiceboxs' rated at 40 amps? lower - higher? @bisco My bad and thanks for the correction about the bolt charging system. I'll do my best to remember the bolt charging stats so I don't make that mistake again. Prime needs at least a 15amp breaker circuit, 20 amps is better and a lot cooler especially in summer sun or inside a non air conditioned garage. see also: @bisco post above about outlets and the plugs that fit into them.
This sounds like a very bad idea. Two L2 EVSEs on a single breaker is likely a code violation and a safety hazard. Give them separate circuits. Two L1 EVSEs used off-label at 240V on a 30 or 40 amp breaker might not draw many complaints. If a Toyota L1 is combined with the Chevy L2 on a 40 amp breaker, then the Chevy unit must be throttled down to 20 amps / 4.8 kW in order to avoid a prima facie violation of allowed current. I believe I'm seeing Bolts rated for L2 charging in the 7 to 8 kW range, and able to use the full long-term current (32 amps) allowed on a 40 amp-rated circuit.
I I plan on charging my prime mostly on a level 1 charger that’s on a separate circuit from my wife’s level 2 charger. But I want to use her charger on occasion when she’s not using it.
That ought to be no problem at all. Use her EVSE as is, when it is open. It and the car will communicate and select a rate that is acceptable for both. Just DON'T add any other outlet to that EVSE's circuit. That is a recipe for trouble. EVSEs should always have their own circuit, never sharing the same breaker and circuit wiring with another EVSE. It will be common for L1 EVSEs to be sharing circuits with lights and other garage and household appliances. If so, do watch to make sure you don't have too much load active at any one time. If there is some overloading problem, note that you can change a charging setting on your Prime to pull only 8 amps, instead of the usual 12 amps. L2 EVSEs shouldn't be sharing circuits with any other devices at all. Unless they 'share' just a single outlet, where one must be unplugged before the other can be plugged in.
If I were to install an EVSE right now, I would install one that has J1772 and NACS plug(s) built-in. With many 2025 EV cars changing to the NACS format, it's the most future proof way to go without having to deal with adapters.
