On Voyah Technology Day on November 4th, Voyah released its ESSA + SOA centralized electronic architecture for electric vehicles.
This release conference was “extremely hardcore” and focused on the achievements and hardcore parameter information that Voyah has gained in electric vehicle architecture. Unfortunately, Voyah’s new sedan – Zhui Guang – did not receive any announcements. Voyah stated that Zhui Meng will be released again in December of this year.
Let’s talk about the ESSA electric architecture
ESSA can be understood as Voyah’s new platform. Voyah’s Dreamer is based on the ESSA architecture.
According to Voyah CEO Lu Fang, the ESSA architecture has complete independent intellectual property rights. Its main advantages are expressed in three aspects: the three electric systems, the chassis, the safety, and the expandability.
In terms of the three electric systems, its battery discharge peak power can reach 500 kW, the battery life can reach a driving distance of 300,000 kilometers, the performance attenuation is less than 5%, and the energy density is 212 Wh/kg. For comparison, the battery energy density of the Alpha T from Jihoo is 194.12Wh/kg.
In terms of the motor, Voyah uses an 8-layer flat wire drive motor. The maximum power of the dual motor is 360 kW and the torque is 740 Nm.### Charging Power
The home charging of this vehicle can support 11 kW three-phase power, with a maximum output power of 3.3 kW.
Chassis
The chassis adopts front double wishbone + rear five-link configuration, of which aluminum alloy accounts for more than 90%. The suspension configuration is air suspension + CDC adaptive damping suspension.
Torque Control
ESSA is also equipped with a torque control system that is similar to BYD’s iTAC intelligent torque control. It can distribute the torque of the four wheels in real time according to the road conditions to maximize the tire grip.
Safety
In terms of safety, there are mainly high-strength body structure, overall safety measures from the core to the BMS to the battery pack, and active safety.
Lastly, let’s talk about its extensibility. ESSA supports vehicle models with a wheelbase of 2,800 to 3,200 mm and covers from B-segment to E-segment vehicles.
In the future, ESSA will also support 800 V high-voltage platform, installation of laser radar, and hydrogen energy power.
Intelligent and Networked SOA Electronic and Electrical Architecture
The SOA architecture is somewhat similar to the internal network structure of LanTu. To truly understand its internal structure, we will highlight several key points.
Firstly, the central controller OIB integrates the four controllers of vehicle control, power, intelligent driving, and intelligent cockpit, making future upgrades easier.
# Domain Controller VIU
The Domain Controller VIU integrates various standardized parts, which can reduce the cost of maintenance and repair. In the future, it will also be able to connect to higher-level auxiliary driving hardware devices.
Car Networking T-BOX
Car Networking T-BOX, which is a networked system that should be familiar to everyone. SOA can support 5G network OTA, cloud data computing, etc., which enhances the overall intelligence level of vehicles.
Finally, SOA reserves more than 300 interfaces and calls on developers to develop various apps or ecosystems independently on Landtu vehicles.
Interestingly, in a video explaining the Landtu SOA architecture, there is an interior image of a new Landtu car. In addition, the Landtu Zhui Guang is expected to be Landtu’s first sedan model equipped with the ESSA platform + SOA electronic and electrical architecture.
We have reasons to suspect that the interior image of the car that appeared in the demo video may be the interior style of Landtu’s new sedan, Zhui Guang.
Well, what do you think of this triple-screen? Do you think Landtu’s architecture is “new” enough? Leave your thoughts in the comments below!markdown
