Thinking about how this magic happens? Let’s get a closer look at V2L’s inner workings.

How does V2L Work? 

V2L technology-embedded automobiles have an onboard Converter that changes the battery from Direct Current (DC) to Alternating Current (AC). 

To actively use V2L technology, you require a V2L adaptor, which plugs into the car's charging port and provides a socket.

Upon activating the car's V2L mode, the battery's energy is transformed and supplied to the linked device via the adapter and cable. 

Power management and DC to AC conversion occur inside the car. However, the adapter manages the load and facilitates power flow to the cable.

But how much power are we talking about? Let's crunch some numbers.

V2L Power Output Ratings and Capability

Understanding V2L power output ratings and capabilities is essential for maximizing the utility of electric vehicles beyond transportation. This overview explores key considerations.

Power Output Ratings Explained:

  • Maximum Output: Using V2L technology, power output ratings show the most electricity an EV can provide to external devices.
  • Put into Watts: These ratings, which are usually expressed in watts (W), specify the speed at which devices can be powered or charged.
  • EV Battery Capacity Impacts Power Output Capacity: The size and capacity of the EV's battery impact its power output capacity.
  • Compatibility considerations: Devices must comply with the EV's power output specifications for effective and secure charging or operation.

Implications for Device Charging:

  • Charging Speed: Faster device charging is possible with higher power output ratings.
  • Compatibility: EVs with lower power output ratings might not be able to charge devices with greater power requirements effectively.
  • Device Safety: Safe and efficient charging prevents possible damage to devices or EV systems by matching device power requirements with EV power output ratings.
