Electric vehicles are becoming faster, more powerful and more convenient. One of the main technological trends is the transition from 400V to 800V platforms, which allows you to charge faster and improves efficiency. Let's look at the difference between these architectures and which brands use them.

What's it?The 400-volt system is the traditional standard used by 80% of all electric vehicles.

Positive:

✅ Availability – Most charging stations support 400V.

✅ Simple and proven technology.

✅ Cheaper to manufacture – reduces the cost of electric vehicles.

Minuses:

❌ Limited charging speed – usually 80-160 kW/h.

❌ Lower efficiency at high power.

Which electric vehicles use 400V?  🚘 Tesla Model 3/Y, Volkswagen ID.4/ID.6, BYD Seal, Zeekr 001, Hyundai Kona EV, Kia Niro EV, BMW i4, Mercedes EQA/EQB, Nissan Ariya.

What's it?800V is a new architecture that allows electric vehicles to charge faster and more efficiently.

Positive:

Super–fast charging - from 10 to 80% in 15-20 minutes.

✅ Higher power – supports charging up to 350 kW.

✅ Better energy efficiency – less energy loss during movement.

✅ Lower battery weight – lower current load = thinner cables.

Minuses:

❌ More expensive technology.

Limited infrastructure – not all charging stations support 800V.

Which electric vehicles use 800V?  🚘 Hyundai Ioniq 5/6, Kia EV6/EV9, Porsche Taycan, Audi e-tron GT, Zeekr 009, Lotus Eletre, Lucid Air, BYD Yangwang U8.

• A 400V EV with a 250 kW charge gets ~200 km of mileage in 20-30 minutes.
• The 800V EV, when charged at 350 kW, gets 300 km in 10-15 minutes.

Example:

Hyundai Ioniq 5 (800V) charges from 10% to 80% in just 18 minutes at 350 kW.

A Tesla Model Y (400V) at the same station will spend 30-40 minutes on a similar charge.

800V will soon become the standard – companies are massively switching to this architecture.

The emergence of 1000V+ platforms – new Chinese EVs are developing 1000V systems (for example, Nio ET9).

🔹 Development of the charging infrastructure – the growth of 350 kW stations will accelerate the transition to 800V.

Which platform do you prefer? Is charging speed more important to you than the availability of charging stations? Let's discuss it! ⚡🔋
