2. Charging Requirements of the Tesla Model 3
2.1 Diverse Charging Scenarios
Home Garage: Overnight slow charging dominates, but occasional urgent top-ups are needed.
Outdoor Trips: Queues at highway rest-area chargers and compatibility issues frustrate drivers.
Emergency Replenishment: During long-distance drives, sudden low state-of-charge requires rapid recovery.
2.2 Advantages of DC Fast Charging
| Charging Method | Power Range | Typical Range Added (30 min) | Application Scenario |
|---|---|---|---|
| AC Slow Charge | 3–7 kW | 30–50 km | Home/Office overnight |
| DC Fast Charge | 30–60 kW | 150–300 km | Highways/Emergency |
| Portable DC Charger | 20–30 kW | 100–200 km | Flexible/Emergency Use |
Table 1: Comparison of Charging Methods
While the Tesla Model 3 comes with an onboard AC charger, DC fast charging currently relies on public stations. Portable DC chargers fill the gap between home AC charging and public DC stations—combining high speed with portability.
