Mercedes-Benz EQE and EQS Upgrading EVA2 to 800V Platform for EV Charging Over 200kW

2023-2024 Mercedes-Benz EQE SUV EV

According to reports from German automotive media, Mercedes-Benz is planning to upgrade its modular EVA2 electric vehicle platform to an 800V high-voltage architecture. This will enable much faster charging capabilities for Mercedes EVs.

The new 800V system will allow for charging speeds over 200kW, a major upgrade from the current 400V platform’s limit of 170kW. Mercedes-Benz EQE SUV and EQS models are expected to be the first to benefit from the high-power charging performance.

Making the jump to 800V is becoming an industry trend as automakers aim to minimize EV charging times. Porsche’s Taycan electric sports car also uses an 800V system to achieve incredibly fast charging.

Mercedes’ next-gen EVA2 platform, reportedly called EVA2M internally, incorporates several other improvements beyond 800V. An all-new in-house developed electric drive unit (eATS 2.0) will provide more power and efficiency.


The new eATS 2.0 also enables a transition from single-speed to multi-speed transmissions. The addition of a two-speed gearbox gives Mercedes more flexibility in optimizing power delivery.

Existing EVA2 models like the EQS and EQE SUV have already implemented upgrades for practical range too. Those include a heat pump for climate control efficiency, optional 22 kW AC charging, and disconnecting front axle motors when not needed.

But doubling the voltage to 800V is the most impactful change, future-proofing Mercedes EVs for evolving ultra-fast charging infrastructure.

The EVA2 upgrade demonstrates Mercedes-Benz’s continuing push to enhance electric driving experiences as it rapidly expands its EV portfolio. Combining 800V charging with larger batteries and more advanced motors will keep driving ranges and performance competitive.

Within a few years, most Mercedes shoppers browsing EV model lines like the EQE, EQS or EQA may find 800V and 200kW+ charging speeds simply become the new norm.
