Leviton Charger - 30A

[pwdrescher]

Hey guys. Getting a new Taycan soon but live in an apartment building that has (4-5) Leviton 30A chargers. I want to confirm that these chargers work with the Porsche Taycan and if anyone has used any tips or things to know. Can't wait for the car!

They'll work. They are likely J-1772, and if not you can always get an adapter.

+1 for @Miwa

but what if its quality is like their $10 14-50 NEMA outlets...

Attached are some photos. Let me know if I will need any adaptor. Are these considered 'ok' chargers? Can I use their plug? Also, the plug image is the plug I have at work, does that work?

it’s standard it will work fine

based on pics no adapter required

How long does a charger like this typically take for full charge?

How long does a charger like this typically take for full charge?

it depends - the 30 amp rating is vague

if it’s a 30 breaker - then it’s 24 amps charge rate - which is 5.76 kW
if it’s a 30 amp charger - then it’s 7.2 kW

the Taycan has a 93.7 kWh battery - 83.4 kWh ”usable” - so we’ll use 84 kWh for a “full” zero % charge estimate…

84 kWh / 5.76 kW = 14.53 hours - let’s say 16 to 17 hours for a “full” zero % to 100% charge
84 kwh / 7.2 kW = 11.67 hours - let’s say 13-14 hours for a ”full” zero % to 100% charge

NOTE: charging from zero to 100% is very very rare - I’ve only gotten down to 3% once in owning eV’s over 7 years - most of the time you’re charging from like 40% to 85% for normal daily use - or about a 45% spread - and you rarely charge to 100% (85% max daily charge is common to preserve battery health)

45% of 84 kWh is 37.8 - let’s say 40 kWh - or about 80 - 120 miles of daily driving

40 kWh / 5.76 kWh = 6.94 hour - round it up to 8
40 kwh / 7.2 kwh = 5.55 hours - round it up to 6 1/2 or 7 hours

it all depends on if it’s a 30 amp leviton charger on a 30 amp breaker which then means you actually only get 24 amps - or if it’s 30 amp Leviton charger (on a 40 amp breaker) which means you actually get 7.2 kW.

we round “up” charging estimates because charging is not 100% efficient and there is overhead - but once you own an EV you will find charging times are very very consistent for a given start % to a given ending % for the same charger - over the years for the same “delta” of battery percentage across all my EV’s (taycan included) the charging time only varies 5-10 minutes in total time take - and the car will tell you when the charge will be done and it’s also very accurate.

you might find this thread useful - becuase it goes over different EV charging speeds and total charging time taken - over the life of your Taycan you’ll mostly charge it at home, but you will also charge in from other chargers “in the wild” during your travels - in North america you’ll find charging rates vary from 12 amps (low end) to 48 amps (high end) - and really really fast DC chargers 400V/800V 25 kw - 270 kW affairs…

How long does a charger like this typically take for full charge?

the snarky answer is “it depends” - but you need to know two facts to estimate charging time:

1. kWh required (kilo-watt hours) - this is the amount/capacity of power you are trying to add to the battery
2. kW (kilowatts) - this is the rate at which you are adding power

kilowatts is simply ’Volts (V)’ multiplied by ’Amps (A)’ - V * A = watts (W) - then divide by 1000 to get kiloWatts

240 volts * 30 amps = 7,200 watts or 7.2 kW
240 volts * 40 amps = 9,600 watts or 9.6 kW

if you charge an EV (any EV or PHEV) from a charger providing 7.2 kW for one hour you will have “added” 7.2 kWh to the battery after one full hour of charging…but that assumes 100% efficient charging - which does NOT happen - so after our “pure” calculation we add a fudge factor and run up the estimate a little bit to account for charging losses

the are 3 main voltages you will encounter in North America

120 volts (household outlets)
240 volts (residential “appliance outlets)
208 volts (commerical properties)

voltages actually vary from 110-130 volt and 210-250 volts - changing the calculations slightly - but in practice the “ideal” 120 & 240 volt numbers work for estimating charging time

so you need to know if your EV charger is 120V (L1) charger or a 240V (L2) charger - and it’s amps - once you have an EV chargers volts & amps - you can do the math to get the KW - and then you can use the EV charger KW number to estimate how long it will take to charge your EV battery by figuring out roughly how many kWh you need to “add” to the battery based on battery % you are attempting to add…

MOST non-fast DC chargers will will encounter in North America will be between 6 kW and 9.6 kW (30 amp to 40/50 amp chargers) - there are other chargers (bigger and smaller) but they are less common than the 30/40/50 amp variety…

clear as mud?

if this plug is available to you from your pictures

this could be good for you

that is a NEMA 14-50 plug - which if wired correctly means is on a 50 amp breaker which can offer a 40 amp charge rate or 9.6 kw - that plug should charge your taycan much faster than the 30 amp levition chargers - but you will need the porsche PMCC or some other J-1772 40 amp EV charger - verify with building management it’s a 50 amp breaker and you are good to go with any 40/50 amp J-1772 EV charger (EVSE) - porsche or otherwise
