Tesla Model Y Performance Introduces Bidirectional Charging with V2L and V2H Support

Tesla Model Y Performance has officially confirmed its support for V2L (Vehicle to Load) and V2H (Vehicle to Home) bidirectional charging capabilities. This announcement was made by Tesla in response to inquiries on social media. The new Model Y Performance will allow users to power external devices, making it ideal for camping or temporary setups.

Overview of V2L and V2H Capabilities

The V2L functionality allows for an output of up to 2.4 kW using a dedicated adapter, which is capable of powering small devices. This setup is suitable for various applications, including camping and outdoor events. The Model Y can also support V2H functionality when paired with a Tesla Gateway or Powerwall 3, providing a home electricity supply during outages.

Specifications and Performance

The V2L feature primarily serves to power external devices such as tools, camping gear, or household appliances. It requires a Tesla-specific adapter or third-party accessories to connect to 120V and 240V outlets, with a maximum output power of 11.5 kW and a sustained output of about 3–5 kW.

Using the Tesla Powershare Outlet Adapter, the charging port can be converted to a 120V 20A outlet with a maximum output of 2.4 kW. This design supports various appliances such as refrigerators, fans, electric cookers, sound systems, and laptops, making it perfect for outdoor usage.

Cost and Installation

The installation costs for V2H, particularly in North America, range from $1,000 to $2,500 (approximately NT$30,400 to NT$76,100), enabling a typical American household to meet its electricity needs for 2 to 3 days during a blackout. Both V2L and V2H functionalities can be activated through the Tesla App, but users must upgrade to the 2025.20 OTA software version for proper operation.

Battery Life and Efficiency

With a battery capacity of approximately 75–82 kWh, the Model Y Performance can theoretically run for over 30 hours on a continuous output of 2.4 kW while retaining 20% of the battery for driving. This is especially adequate for camping or temporary setups. In contrast, the Cybertruck, equipped with a 123 kWh battery, can output up to 9.6 kW, running for about 12 hours under full load or over 3 days with basic appliances.

Ease of Use and Safety Features

The bidirectional discharge operation is straightforward, with owners able to switch to Powershare mode via the Tesla App while parked. The output efficiency for V2L is around 90%–95%, which is more efficient than traditional UPS systems. Tesla has also designed comprehensive safety mechanisms for V2L, including overload, overheating, and ground protection, which have received UL and FCC certifications.

Comparison with Cybertruck

The Cybertruck’s V2L configuration is more comprehensive, featuring 4 x 120V and 1 x 240V outlets, with a maximum output of 9.6 kW, allowing it to support multiple high-power devices simultaneously. While the Model Y requires an adapter costing approximately $80 (around NT$2,436), the Cybertruck’s built-in outlets eliminate additional accessory costs, making it more convenient for users.

Final Thoughts

For those considering long-term backup and power management, Tesla’s home energy storage product, Powerwall, is worth exploring. Unlike traditional generators, Powerwall operates quietly without fuel and can automatically detect power outages, providing immediate backup power to homes.

Market Observations

In the Chinese market, there were instances of unofficial V2L discharge kits being offered by third-party manufacturers. These kits exploited loopholes in the GB/T DC charging protocol, allowing the Tesla to mistakenly think it was charging while actually discharging power to external devices. However, these offerings lack safety mechanisms and stability, posing risks to the vehicle’s warranty and components. In contrast, the V2L and V2H capabilities of the 2025 Model Y Performance are officially supported by Tesla and come with safety certifications, providing a more reliable energy solution.
