Charging hardware will normally reach high temperatures during prolonged use
• High ambient temperature may cause stopped, slowed, or derated charging sessions
•The optional Charging Dock (7PP.915.706.A) traps multiple heat sources (receptacle, plug, supply cable, charge control unit, and part of the vehicle cable) and may exacerbate charger derating or stopped charging sessions
•The optional 7.5m vehicle cable is often wrapped around the charging dock. This further heats the charging dock during/after prolonged use, especially if the vehicle is parked close to the charging dock where less vehicle cable is needed.
•The 10 AWG supply cables are tested and certified for use in US and Canada, and may differ from other cord-and-plug EVSEs readily available in the market
•It is recommended to install or relocate installed charging hardware away from vehicle heat sources or heat exchanger exhaust air (for example, away from the Taycan front wheel opening)

my take aways

• yeah we know our EVSE's run really hot - we're good with this
• the charging dock is being rebranded as a home micro-sauna
• again our cables run so hot don't aggravate the problem
• our power supply cable is a super good design honestly it is - why won't anyone listen to us??? It's perfectly safe and appropriate - we know other vendors do it differently - it's just fine!!
• you shouldn't install our EVSE right next to the charging port -you know the best place to install it given the vehicle port location and the short EVSE cord we provide to reach the charging port - yeah that location - it's the worst!!!
  • it should be installed far enough away that the cord won't reach or get the $1120 25 ft cord so you can install the EVSE far enough away from the vehicle that it won't super heat…
  • please do not consider any other vendor's less than $700 EVSE's that come with 25 ft cords and run cooler - ours is great - honestly it is.

@daveo4EV and other forum members omitted this 'tip' from all their posts about planning and installing home charging equipment.
