General
What are the basic types of EV charging?
Types of Charging:
- Level 1(AC) 7~9.6kW: Standard home outlet charging, ideal for overnight charging. Most economical but slowest option.
- Level 2(AC) 11-22kW: Workplace and public charging, balanced speed and cost. Commonly used for daily commuting.
- DC Fast Charging (50-350kW): Highway and commercial deployment, rapid refueling, essential for long-distance travel.
- Ultra-Rapid Charging (350kW+): Latest generation technology, fastest available.
What are different charging standards and vehicle compatibility?
- Global Standards:
- CCS (Combined Charging System): Primary North American and European standard. Supports both AC and DC charging, compatible with most modern vehicles.
- CHAdeMO: Developed for Japanese vehicles, still present in many regions. Some Tesla models in Japan also support this standard.
- GB/T: Chinese national standard used exclusively in mainland China. International vehicles may need adapters in Chinese markets.
- Tesla Supercharger: Historically proprietary to Tesla vehicles. Now gradually opening to other manufacturers in select regions.
- Type 1 / 2: An AC charging standard used in the Americas, Asia, and Europe. It offers slower charging speeds and is extremely common in public charging networks.
How long does it take to fully charge an EV battery?
What are the specific steps for charging at a public station?
- Locate and park: Drive to available charging spot clearly marked for EV charging at the station.
- Select charger: Via touchscreen or mobile app, identify an available charging unit matching your vehicle type.
- Insert connector: Firmly plug charging connector into vehicles.
- Begin charging: Automatic initiation occurs within seconds; charger display or app confirms active charging.
- Monitor progress: Track charging status through app or charger display throughout session.
- Automatic completion: Charging stops automatically when target charge level reached; notification sent to phone.
- Verify payment: Authenticate using app, RFID card, or contactless payment method at charger interface.
- Disconnect and depart: Unplug connector, wind cable neatly, and move vehicle to free space for other users.

Benefits
How do I effectively reduce my EV charging costs?
- Membership Savings: Analyzing monthly charging costs shows subscriptions typically save 10-30%..
- Time-of-Use Optimization: Shifting charging to off-peak hours qualifies you for 20-40% discounted electricity rates.
- AC/DC Charging Strategy: Prioritize AC slow charging for daily needs; reserve fast charging for essential trips to avoid premium rates.
- AC versus DC: Prioritize AC slow charging for daily charging; reserve fast charging for necessary situations reducing premium charges.
- Home Charger Installation: Installing a personal Level 2 charger is often the most economical long-term solution; government subsidies can offset part of the cost.
- Preventive maintenance: Regular vehicle and charging system checks prevent expensive emergency repairs disrupting charging patterns.
Will EV charging dramatically increase my electricity bills?
- Monthly addition: Average EV charging increases electricity costs $15-40 monthly for typical usage patterns.
- Calculation basis: Typical EVs consume 15-20 kWh per 100km equivalent to $2-4 per 100km electricity costs.
- Off-peak advantage: Strategic off-peak charging reduces electricity cost increases to $15-25 monthly range.
- Gasoline comparison: Despite electricity increase, eliminated gasoline expenses typically exceed additional electricity costs 2-3x.
- Total savings: Overall transportation costs typically decrease 40-60% despite higher electricity bills.
Charger & Battery
Will charger failure damage my vehicle?
Why does charging slow down after reaching 80% charge?
- Technical Reasons for Deceleration:
- Battery protection protocol: Manufacturers deliberately reduce charging power at high state-of-charge to prevent stress on battery cells and extend overall lifespan.
- Thermal management: High-power charging generates significant heat, particularly at high charge levels. System reduces current to maintain safe temperature ranges.
- Battery management system logic: BMS automatically optimizes charging parameters based on real-time battery state and environmental conditions.
- Best practice recommendation: For daily charging, stop at 80% for optimal battery health; only charge to 100% when planning long trips requiring maximum range.
Does fast charging damage the EV battery?
What should new EV owners know about charging?
- Initial charging: Begin with familiar, lower-risk charging locations (home or trusted public chargers) rather than rushing to fast charging.
- Optimal range: Maintain daily charge between 20-80% for maximum battery lifespan; only charge to 100% for long-distance trips.
- Route planning: Use aggregation apps to preview charging stops before long trips; identify backup stations for redundancy.
- Time budgeting: Factor 30-60 minutes per long charging stop into trip estimates; modern trips involve planned charging pauses.
Can charging equipment damage or ruin my EV battery?
Usage Guide
How do I find nearby charging stations?
- TDC Official App: The TDC Charging App offers comprehensive coverage and real-time information on available charging stations.
- Aggregator Platforms: Use charging station maps such as PlugShare, ChargeHub, and OpenChargeMap.
- In-Car Navigation: Utilize your Hyundai electric vehicle's built-in navigation system.
- General Map Services: Access universal mapping software like Google Maps, Apple Maps, and Waze.
Can I reserve or book charging spots in advance?
- Reservation Details:
- Booking Window: Advance reservations are typically available 24–72 hours before your desired charging time slot.
- Cancellation Policy: Cancellations made at least 30 minutes prior to the start time incur no penalties or fees.
- Reservation Holding Period: The station holds your reservation for 15–30 minutes after the scheduled start time; exceeding this grace period may result in the spot being released.

Why does charging fail or show 'communication error'?
- Troubleshooting Steps:
- App connectivity: Check WiFi signal strength or switch between WiFi and mobile data; restart app if necessary.
- Alternative charger: Move to different charger at same location; confirms whether issue is network-wide or single unit.
- Payment methods: Verify account balance sufficiency; update payment method in settings if charge declined.
- Signal quality: Walk to better signal area away from physical obstructions or metal structures; retry transaction.
- Adapter compatibility: Confirm connector type matches vehicle requirements; use correct adapter if needed.
