1. V4 Cabinet Technology

The V4 cabinet is the core hardware advancement in Tesla's latest charging system. According to Tesla charging director Max de Zegher, the new design represents significant improvements over previous generations.

Key technological advancements:

3X power density increase over previous models
2X stalls per cabinet capacity expansion
500kW total power support per cabinet
Up to 8 charging stalls from a single cabinet

Comparison with previous generation:

V4 Cabinet: 500kW power supporting 8 stalls
V3 Cabinet: 250kW power supporting 4 stalls

This enhanced design enables higher charging capacity in limited space. It facilitates charging station construction in dense urban areas.

2. Charging Performance

V4 Superchargers offer improved charging capabilities across multiple vehicle types. Technology supports a wide range of electrical architectures.

Technical specifications:

400V to 1000V vehicle architecture support
Cross-brand compatibility for non-Tesla EVs
Tesla Semi 1.2MW charging capability
Unified hardware for passenger and commercial vehicles

Actual charging performance:

Cybertruck: 44% charge in 15 minutes (13% faster than V3)
500kW peak power maintained briefly at very low battery levels
10%-80% charging: 4 minutes faster than V3
400V Tesla models: Limited to 250kW charging speed

Currently only Cybertruck with 800V architecture can utilize the full 500kW power. Other Tesla models maintain their existing charging limitations.

Charging time comparisons:

V4 Supercharger: Fastest overall performance
325kW V3.5: 3 minutes slower than V4
Standard V3: 4 minutes slower than V4

Charger Type	Max Power	Stalls per Cabinet	Key Advantage
V4 Supercharger	500kW	8 stalls	Highest density
V3 Supercharger	250kW	4 stalls	Previous standard
V3.5 Supercharger	325kW	4 stalls	Intermediate upgrade

3. Network Deployment

The V4 cabinet's design advantages extend beyond individual charging performance. It offers significant benefits for network expansion and operation.

Deployment benefits:

Reduced hardware costs per charging stall
Shorter construction time for new stations
Higher capacity in limited urban spaces
Simplified layout and installation

The V4 cabinet supports 400V to 1000V vehicle architectures, making it compatible with future EV designs. This forward-thinking approach ensures long-term relevance.

Future development plans:

Current availability: Tesla owners only
Q4 2025 target: Open to non-Tesla EVs
Continued network expansion with V4 technology
Industry-wide charging infrastructure advancement

The V4 Supercharger represents a fundamental shift in charging network design. It combines higher power delivery with improved deployment efficiency for sustainable growth.
