For example, the Lynk & Co 08 EM-P has a maximum torque of 905N·m and a maximum acceleration of 4.6 seconds, and the Lynk & Co 09 EM-P has a maximum torque of 844N·m and a maximum acceleration of 4.9 seconds.
This outstanding performance is inseparable from the four-wheel drive system of Lynk & Co EM-P, which significantly improves the stability, handling and passability of the vehicle, making trekking through mountains and rivers easier. Taking the Lynk & Co 08 EM-P as an example, we will introduce in depth the important support of the four-wheel drive system - the P4 motor.
What is a P4 motor?A P4 motor is a motor that does not have the same output shaft as the engine and can directly drive the vehicle, usually located on the rear axle.
The advantages of the P4 motor are significant: powerful power, lower energy consumption and more comfortable driving
High integration and lightweight: OBC/DCDC/PDU is integrated in one piece. The motor adopts a multi-layer concentric winding flat wire hair-pin design, and the system power density is as high as 2.2kW/kg, exceeding the 2.0kW/kg planned by the industry in 2025. The self-sealing welded differential is coaxial design with parallel shaft, which is more compact.
High efficiency and more energy saving: The P4 motor is a flat wire oil-cooled motor, and the system WLTC efficiency ≥ 89.04%, which is higher than the industry average (85%-87%).
High reliability, peace of mind: based on European luxury brand development verification standards, global joint development. The total test mileage in the development test is 5 million kilometers. The design life is 350,000 kilometers, far exceeding the industry average of 150,000-250,000 kilometers.
Excellent NVH performance, more comfortable driving: The stator of the P4 motor adopts a low cogging torque design, the rotor adopts a unique inclined pole design, which can effectively suppress torque ripple, and adopts random switching frequency and harmonic injection to suppress high-frequency noise. Under all working conditions, the NVH is reduced by 5dB compared to competing products, which is quieter.
What is OBC, DCDC, PDU? What is a flat wire oil-cooled motor?
- OBC: On-board charger for connecting to an AC charging pile to convert AC power into DC power.
- DCDC: A DC converter that converts the high-voltage output of the power battery into the low-voltage required by each consumer.
- PDU: Power distribution unit used to distribute direct current to the battery output and monitor overcurrent and overvoltage.
- Flat wire oil-cooled motor: A motor that uses a flat copper-clad wire winding stator and oil-cooled technology. Flat wire windings can improve the power density and efficiency of motors, while oil cooling technology can effectively reduce the temperature rise of motors, improve their reliability and life.
Paired with DHT Evo, it forms an electric four-wheel drive system: no softness at high speed, no panic at off-road, and worry-free in all scenes
The P4 motor of the Lynk & Co 08 EM-P has a peak power of 156kW and a peak torque of 290Nm. Together with the dual-motor electric drive system (including the 3 DHT Evo electric transmission, P1 motor and P3 motor), the powerful electronic all-wheel drive system greatly improves the vehicle's acceleration and off-road driving ability.
First, the acceleration is rapid
In the case of ejection start or rapid acceleration at medium and high speeds, the vehicle adopts full power output mode. The three motors of P1, P3 and P4 work together with the electric hybrid engine to output power, with strong power output and 000 acceleration in 4.6s.
Second, the control is more stable and prevents skidding
When accelerating into corners, front-wheel drive vehicles are prone to understeer, and pure rear-wheel drive vehicles are prone to loss of traction of rear wheels. Not only does it lose power, but it also tends to skidding when accelerating.
The Lynk & Co EM-P four-wheel drive model flexibly adjusts the torque distribution between the front and rear axles through the front and rear motors, which can effectively adjust the vehicle's cornering attitude and improve the stability of the vehicle's handling. Especially on ice and snow roads, it can effectively prevent side slippage and improve safety.
3. Strong off-road ability
When climbing, the electric hybrid engine is driven by the P3/P4 motor at the same time, achieving a super comprehensive power of 436kw and a peak torque of 905N·m, with sufficient power. The Lynk & Co 08 EM-P achieves a maximum gradient of 60% on dry asphalt roads, making it easier to climb hills.
In the face of muddy roads, the advanced electronic four-wheel drive system of the Lynk & Co 08 EM-P flexibly adjusts the power distribution to effectively suppress wheel slippage and make it easier to get out of trouble.
The P4 motor is paired with a dual-motor electric drive system, giving the Lynk & Co EM-P powerful four-wheel drive performance, faster acceleration, more stable control, and stronger off-roading. Lynk & Co EM-P super extended range electric solution, leading in an all-round way, is super!
