Yes, Supercharge decrease your battery health a little each time you charge it, but don't worry. If you stay your charge always less than 80% then your battery will have long battery life. The faster you charge the battery the higher power is delivered to it.
Charging at a non-Tesla DC fast-charging station leads to damage to battery cells, that is why Tesla will throttle your supercharging rate. When using a Tesla Supercharger, the Tesla network has a built-in battery charging protection algorithm to work together with the Tesla battery.
Superchargers are designed for fast charging and therefore, should only be used for as long as it takes to charge a vehicle. If a vehicle parks at a Supercharger past a full charge being reached, idle fees start being charged.
For vehicles with Lithium Iron Phosphate (LFP) high voltage Batteries, Tesla recommends you keep your charge limit to 100%, even for daily use, and that you also fully charge your vehicle to 100% at least once per week.
While fast charging can increase the rate at which your battery loses capacity, its actual impact is only about 0.1 percent more capacity lost than without using fast charging.
No. But it does degrades it slightly faster. So you want to avoid it when possible. There is a Tesla that has been supercharged to 100% multiple times a day, and it made it to almost 200,000 miles before it was replaced (under warranty).
In simple terms, charging an EV battery to 100% will lead to a reduction in the total usable capacity of the battery. It might not be noticeable at first, but your battery will gradually lose its range as it degrades over time.
Until then, we ask that vehicles be moved from the Supercharger once fully charged. A customer would never leave a car parked by the pump at a gas station and the same thinking applies with Superchargers.
Supercharging is best reserved for long-distance travel. One should not consider Supercharging for their daily charging needs since daily Supercharging will reduce the life of the battery. Additionally, it's both cheaper and more convenient to charge up at home.
Your Tesla vehicle is designed to maintain its battery over time, and will not overcharge when plugged in for an extended period. For that reason, when you're away from home, we always recommend leaving your vehicle plugged in.
Less efficient: the biggest disadvantage of superchargers is that they suck engine power simply to produce engine power. They're run off an engine belt connected to the crankshaft, so you're essentially powering an air pump with another air pump.
A supercharger puts a huge amount of stress on an engine through kinetic energy and heat production, therefore many engine components have to be over-engineered to cope with the additional strains put upon them. In most cases, this then leads to added weight and diminishing returns in terms of performance.
Tesla's position on Superchargers
In both cases there are no limitations or restrictions on how often or for what purpose you use the Supercharging network.
As the world's economy struggled, Tesla's sales and production rates also dropped, and as a result, Tesla was forced to reduce the starting price of several models as well as remove the unlimited supercharging perk indefinitely.
A supercharger belt has a life expectancy of 80,000-110,000 km, and should be replaced before reaching this point.
If you really need the range, go up to 90-95%. Electric car batteries should not, generally, be charged to 100%. Long-term, this reduces(opens in a new tab) the battery's longevity, and Tesla cars actually charge up to 90% by default.
Why is Supercharging so much faster than charging at home? Superchargers skip the onboard charger of the vehicle, providing up to 120kW of direct current (DC) power to the battery. This level of power requires dedicated transformers and utility connections which are not available in residential situations.
You can supercharge the car as often as you need to. On road trips I've charged 3–4 times a day for a week.
Most of the cost difference depends on daytime versus overnight charging, so you'll usually pay less to charge from 9 pm to 11 am.
Slower charging means that the lithium-ion battery pack heats up much less, and that helps the battery to retain capacity and chemical balance better. The faster you charge, the more heat is generated and over time this heat can degrade the Li-ion battery.
If the Battery's charge level falls to 0%, you must plug it in. If you leave it unplugged for an extended period, it may not be possible to charge or use Model Y without jump starting or replacing the low voltage battery. Leaving Model Y unplugged for an extended period can also result in permanent Battery damage.
Most of the time you should only charge an EV to 80% because charging rates slow down dramatically past the 80% mark. And two, the long-term health of your vehicle's battery pack is improved when kept below 100%.
Steady driving at highway speed drains the battery much faster than driving in stop-and-go traffic – but anywhere you are driving, freeway or side road, driving faster consumes more of your battery than driving slower.
CHARGING TOO OFTEN
Charging too often. Generally speaking, don't charge every day unless you need to. Natural degradation may occur in the battery based on the number of charging cycles that are used over its lifespan. EV Battery performance and durability can deteriorate if the charger is used constantly.
