Tesla takes about 10 hours to charge once. Here is an introduction to Tesla: 1. Introduction: Tesla is an American electric vehicle and energy company founded in 2003 in Silicon Valley, USA by Martin Eberhard and Marc Tarpenning. 2. Content: It mainly produces and sells electric vehicles, solar panels, and energy storage equipment. The founders named the company "Tesla" in honor of physicist Nikola Tesla. 3. Development: In June 2021, Kantar released the "2021 Kantar BrandZ Most Valuable Global Brands Ranking," where Tesla ranked 47th.

I've been driving a Tesla Model 3 for three years, and charging time really depends on the situation. Using a standard 220V household outlet, it can only add up to 100 km overnight, which is extremely slow. A 7kW home charging station is better—my Long Range version takes about 10 hours to go from empty to full. The fastest option is still the Supercharger stations: a V3 Supercharger can charge to 80% in 40 minutes, while a V2 takes about an hour. Charging is noticeably faster in summer than in winter, and battery preheating helps stabilize the power output. I usually start charging when the battery drops to 20% for optimal speed. If using third-party fast chargers, the power output might be lower, depending on the operator's equipment.

The last test data was quite interesting: the Model Y can add 300 km of range in 20 minutes using Tesla's V3 Supercharger, but the last 20% of charging slows down to protect the battery. For LFP battery models, charging from 0 to 100% with a 7kW home charger takes about 11 hours, while NMC batteries are about 2 hours faster. If you suddenly find your battery low before heading out, don't panic—just navigate to a Supercharger, and the battery will automatically preheat on the way, allowing full-power charging as soon as you plug in. Charging time nearly doubles at -10°C in winter, but parking in an underground garage can help.

My friend just got the new Model 3, here are some real-world test data for reference: Using a 3rd-gen home charger (11kW) takes 6 hours for a full charge, saving 8 hours compared to the mobile connector. At Supercharger stations when in a hurry, you can add 400 km of range during a meal break. The trickle charging after 80% battery takes about 40 minutes. The new model now supports 800V architecture - just 5 minutes of charging provides 150 km range. It's recommended not to wait until battery drops below 20% to charge, as it's less efficient and harms battery health.
