Shulou(Shulou.com)11/24 Report--

CTOnews.com, April 17, Huawei held the launch of new intelligent electric products and released the charging network solutions of "DriveONE new generation super integrated gold power platform" and "new generation all liquid cooled overcharge architecture".

In the field of power domain, Huawei Digital Energy is positioned as a component supplier dedicated to helping car companies build good cars; in the field of charging network, Huawei Digital Energy is positioned as a solution provider to bring better return on investment for charging operators.

"DriveONE New Generation Super Fusion Gold Power platform" is mainly for B / B + class pure electric, B / B + class extended range hybrid, and A class pure electric vehicle powertrain.

For B / B + class BEV powertrain:

High-efficiency SiC high-voltage synchronous assembly: based on the efficient SiC module and Huawei motor simulation optimization platform, Huawei has built a 92% CLTC powertrain, which is 1.5% more efficient than similar solutions in the industry; this platform supports both 750V and 900kV dual voltage adaptation, which can achieve extremely fast 4C charging on 250A fast charging piles, increase battery SOC from 30% to 80% in 7.5 minutes, and increase battery life by 250km.

The highest density and best auxiliary drive asynchronous assembly in the industry: the total success rate density of power reaches 2.4kW / kg, leading the industry by 30%. Equipped with Huawei intelligent auxiliary drive technology asynchronous assembly, with 92% efficient synchronous rear drive assembly, the overall all-wheel drive mileage can improve 27km.

For B / B + class REV powertrain:

Optimal solution for high-end hybrid four-wheel drive: Huawei brings the industry's first asynchronous five-in-one, with system efficiency optimization and low drag torque design better than 26% of the industry, with efficient rear drive to form the same architecture, four-wheel drive WLTC efficiency up to 88.2%, leading the industry by more than 5%, and 44km mileage is improved when full of fuel. The scheme realizes the optimal design in the Y direction, which can support the upgrading of the suspension of the whole vehicle and makes the arrangement of the double-arm suspension easier.

For A-class BEV powertrain:

Ten-in-one super fusion power domain module: through the first chip fusion, power fusion, function fusion and domain control fusion, the number of BOM is reduced by 40% and the number of chips is reduced by 60%. It can make the automobile enterprises realize the integration of power domain is simple, the verification is simple, the development is simple, and the development efficiency is improved by 30%.

CTOnews.com learned from the official that Huawei's "new generation of liquid-cooled overcharge architecture" has achieved an IRR increase of 66.7 per cent in 10 years through "one architecture, two synergies, and three extremes".

One architecture: full liquid cooling, full modularization, ultra-fast integration, integrated optical storage

Full liquid cooling: through liquid cooling, the life of the product can reach ten years.

Full modularization: create the maximum 720kW of a single cabinet, support 12-way gun line output, and power flexible evolution.

Converged optical storage: by intelligently cutting the wrong edge, the DC stacking efficiency is increased by 2.5% without power expansion.

Ultra-fast all-in-one: to achieve full overcharge coverage full power segment models.

Two Synergy: the Integrated Development of vehicle, pile and Network

Vehicle-pile collaboration: long-term cooperation among authoritative automobile institutions, wide compatibility algorithm; extreme start-up: 50% reduction in charging start-up time compared with the industry; intelligent linkage: strategic cooperation between car companies, differentiated charging experience.

Pile-grid coordination: power grid coordination, demand-side response, VPP, V2G; optical storage coordination, optical storage and charging intelligent scheduling algorithm, the benefit is the best.

Three extremes: extreme experience, extremely high quality, and excellent returns

Ultimate experience: plug and play charging with a success rate of more than 99% +; high-power "5min 200km" charging experience, that is, charging and leaving; lower than the mute charging experience of 60dB.

Extremely high quality: the use of full liquid-cooled overcharge architecture, from a large number of early data simulation to innovative design to strict testing and verification, to ensure the 10-year service life of the equipment.

Excellent benefits: compared with the traditional integrated pile equipment, through power sharing, the utilization rate of municipal electricity is increased by 30%, and the charge can be increased by 30%. Through self-developed topology + liquid cooling + intelligent optimization, the system efficiency is improved by 1%. The intelligent operation and maintenance system is adopted to achieve visual management, and the number of manual visits tends to zero. Finally, the life cycle TCO is reduced by 40%.
