My 2024 RX450h+ is on order and should be in my driveway around the end of the month. I've read through the manual and searched this 5th-Gen Hybrid tech forum, but can't find a clear answer as to what the "MAX" charging current actually is. There are multiple mentions in the manual of setting it to MAX, 16A, or 8A, but I find no definition of what "Max" actually is. The manual's occasionally random use of commas makes it hard to tell whether "MAX" and "16A" are the same value.

Or am I simply misreading this, and one can set the maximum charging current to 16A, 8A, or "the maximum that the source can supply but not more than 16A"?

Thanks in advance for any insights.

 

Max is definitely greater than 16 A - I know that from charging in public L2 chargers, which at Max, takes ~60 % of time necessary at 16 Amps. While its not measurable by the output data from the L2 public chargers - considering that the L2 chargers output 6 kW, and if their voltage output is 240 V or thereabouts - then the current works out to be 6000/240 = 25 Amps. However, the L2 chargers are also spec'ed/capable of 208 V outputs, I believe - so I am not certain that 25 Amps is the actual current, but it's at least 25 Amps at 200+ V is the way I would state it. Setting the Max implies the car decides the maximum it will draw, and be limited only by the external charger's maximum capability - while 16 Amps or 8 Amps means that the car will limit its draw to these values. The L1 charger supplied with the car draws 12 Amps.

 

Great! Thanks, Wrinkle!

I'm currently stuck with a JuiceBox 40 Pro in my garage, and EnelX is dropping all US support... but it sounds like I can trust the RX to draw as much as or as little as it wants. If so, then I can just let the JuiceBox be a dumb device after it goes brain-dead this Friday.

Thanks again.
