## Smart Strategy: Ideal Intelligent Driving Enters the 3.0 Era

Ideal intelligent driving has entered the 3.0 era, from highway scenarios to city scenarios.

**Prediction and Planning: Real-time output of future action trajectories of traffic participants, providing accurate information for decision-making and planning.**


In the upcoming city NOA navigation assisted driving algorithm, Ideal Motors uses three neural network large-scale models: static BEV network algorithm, dynamic BEV network algorithm, and Occupancy network algorithm for reduction, and uses NeRF technology to enhance the Occupancy network algorithm to achieve higher accuracy and details.

Static BEV can supplement the road structure even when part of the camera is blocked and lane lines are blurry, solving the problem of real-time high-precision map data; The dynamic BEV neural network has a certain "mind-reading" ability and is highly similar to the way humans think. For example, when vehicles appear in the field of view of multiple cameras at the same time, the dynamic BEV can stably track and perceive the distance and speed of the object; The Occupancy network algorithm can Data modeling of the physical world, and can restore the real scene of the physical world through pure vision, such as "universal obstacles" such as trash cans and temporary construction signs on the road. Based on the perception results of the above three neural network large-scale models, the system will output real-time trajectory prediction results of all surrounding traffic participants, which can provide accurate information for decision-making and planning of Ideal Motors' intelligent driving system in complex urban scenarios.```
**Training and Perception: Having the Largest Autonomous Driving Training Mileage in China**

Through the continuous accumulation of the past five years, Ideal has owned the most intelligent driving training mileage in China. The training mileage exceeds 400 million kilometers, with a total duration of more than 10.74 million hours, equivalent to a car driving non-stop for 1226 years. And these data are still increasing exponentially. It is expected that Ideal's training mileage will double again next year.

**The City NOA Navigation Assisted Driving System of Ideal AD Max 3.0 Will Start to Be Pushed to Internal Test Users in the Second Quarter of This Year**

**The City NOA navigation assisted driving system of Ideal AD Max 3.0 will begin to be pushed to internal test users from the second quarter of this year. By the end of 2023, the pushed domestic cities will exceed 100**, using one set of technology to fully connect the city and high speed. Part of the intelligent driving capabilities based on large-scale model training will also be released to users who adopt the Ideal AD Pro hardware model. At the same time, Ideal AD Max 3.0 will be perfectly integrated with Ideal 4C Super Charging Station, making it more convenient to go to the super charging station than to go to the gas station.

**Ideal insists on equipping intelligent driving, and the software and services of the NOA navigation assisted driving system of Ideal AD Max 3.0 are provided free of charge for lifetime**.  Intelligent driving will become the real high-value asset of users, rather than a long-term cost burden, and such assets will also be fully reflected in the second-hand car trading.

## Power Strategy: A New Stage of Range Extender and Pure Electric Driving Together

On the pure electric platform, Ideal hopes to enable the family's travel range not only limited to the city, and the complement experience of pure electric users will be the same as refueling.

**800V Super Charging Pure Electric Solution: Make Users Say Goodbye to Range Anxiety and Have a Refueling-Like Replenishment Experience**

In response to the range anxiety problem of new energy vehicle users, Ideal has deeply cultivated core technology and proposed an 800V Super Charging Pure Electric Solution. This set of solutions includes an 800V high-voltage electric drive system based on third-generation power semiconductor silicon carbide technology, batteries with 4C charging capacity, and a self-developed full-stack thermal management system. It increases the charging speed while improving energy efficiency, allowing users to achieve higher charging efficiency and a longer range in various environments. 


Self-developed high-voltage electric drive system assists in improving vehicle energy efficiency in all scenarios.

Ideal automobile’s next-generation self-developed electric drive system will adopt the 800V silicon carbide power module with overall optimized design and advanced resource integration, achieving breakthrough efficiency indicators. The application of the third-generation power semiconductor SiC technology is the key to improving efficiency, and the ability of SiC chips also determines the upper limit of drive performance.

Ideal automobile will adopt a combination of self-developed outsourcing and external procurement strategy, which not only guarantees the supply better but also makes the ideal automobile’s silicon carbide power chips 6\% current ability improvement compared to industry-leading products in the same area by autonomous system-level design optimization, providing stronger power.

At the same time, Ideal automobile’s self-developed 800V silicon carbide power module can support up to 480A of current output, and the module area can be reduced by 50\% compared to mainstream products of the industry with comparable performance at the same current ability. The volume advantage of self-developed power module combined with the integrated design of the motor controller compresses the motor controller to within 4L, and the power density is as high as 62kW/L, thereby reducing the volume and weight of the electric drive system, further optimizing the space and energy consumption of the vehicle.

In addition, in order to solve the problem of charging high-voltage electric vehicles on low-voltage charging piles, Ideal automobile innovatively provides a deeply integrated boost charging solution. By using the inductance characteristics of the motor winding, the electric drive system can be transformed into a boost power supply, allowing users to obtain a fast charging experience of up to 150kW on charging piles with voltages of 750V and below, and the highest charging efficiency can reach 98\%.

Ideal automobile’s self-developed high-voltage electric drive system adopts the third-generation silicon carbide power module and deeply integrated boost charging function, which not only improves the energy efficiency but also covers the fast-charging and energy supplement functions of all scenarios, allowing users to obtain longer range and more convenient fast charging experience in various environments.

Partnering with CATL for dual safety protection in fast charging.

“`To achieve the best fast charging experience for all temperature ranges, Ideal Automotive has collaborated closely with CATL to create the leading fast charging capabilities of the 4C Kirin battery by starting from the design of cell overcharge and battery heat exchange performance.

As for the cell design, the 4C Kirin battery adopts advanced technologies such as high-capacity graphite anode, the cathode with low impedance surface coating, high-conductivity electrolyte, and high-current density top cover design, which enabling the cell to achieve 4C fast charging, and even up to a maximum of 5C. Meanwhile, Ideal Automotive defines the cell design requirements through building a high-precision, multi-field electric-thermal-power model, achieving an ultra-low internal resistance design of 0.3mΩ from multiple dimensions, and significantly reducing the heat generated during the cell overcharge process.

To address the cell heating and cooling issue, the 4C Kirin battery utilizes a dual-side large-area cooling technology which can increase the cell heat exchange area by 5 times compared to the traditional liquid cool base, reduce the thermal resistance by 75\%, and achieve a maximum heat transfer power of 16kW under high-temperature refrigeration. While under low-temperature heating, it can also achieve a 1.6°C increase in cell temperature within one minute. With advantages in various leading technologies, the 4C Kirin battery can achieve an industry-leading and improved charging path at all temperature ranges, with a maximum charging power of 480kW at room temperature and 220kW at low temperatures.

Moreover, with the innovative battery pack integrated design, the number of components in the 4C Kirin battery is reduced by 40\%, and the space utilization is increased by 15\%, maximally providing space for family members in a car.

Ideal Automotive employs a self-developed battery safety cloud early warning system and machine learning battery feature model to fully cover the potential failure modes of the battery, guarding the users’ car safety throughout their entire life cycle. Meanwhile, the Kirin battery’s structure has excellent safety performance. Even in extreme experimental conditions where the battery temperature is heated to 50℃ and the liquid cooling system is turned off, causing a thermal runaway of the cell, the battery has not yet had thermal propagation, and there is no visible fire. This performance is far higher than the industry standard, escorting the safety of every Ideal Automotive user.

The self-developed full-stack thermal management system by Ideal Automotive safeguards broad-temperature-range fast charging. The super heat pump system with ultra-strong cooling and heating capabilities can achieve a balanced wide-temperature range and energy efficiency. In the summer, the system can provide more than 12kW of battery cooling capacity. Facing a cold environment of 0°C in winter, the heating efficiency can still reach over COP3.5. By efficiently utilizing the excess heat of the vehicle, even under the ultra-low temperature driving scene of -25°C, the COP of the heating pump can still be over 1.6, reducing winter heating energy consumption by 35\% compared to PTC scheme.“`markdown
