Compact lithium battery pack 10 years long life

Compact lithium battery pack 10 years of ultra-long life



In terms of battery pack, Pennzoil selects to use the higher technology lithium battery technology. In the lithium battery and nickel metal battery two, the lithium battery energy density is large, more efficient. In order to ensure that the Benz S-Class sedan space and comfort on the requirements of the Benzene, Benzene used a compact design of the lithium battery pack. It is understood that this set of battery pack consists of 35 cells, can supply 19KW of power, capacity of 6.5Ah. This set of battery pack by the German Continental (ConTInental) and JCS Saft together with the development of compact lithium battery structure is very compact, directly it can be installed in the engine compartment.

 

On the other hand, the long design life is another major feature of this battery pack. Since the hybrid system only uses about 10% of the total lithium-ion battery pack in daily conditions, this ensures that the Benelux can supply 10 years of battery life protection. Compared to Japanese cars (such as the Lexus LS600hl as representative) that pick strong hybrid skills with beautiful data, the Penske S400 HYBRID picks hybrid skills that pay attention to longevity, which shows a very different direction of development.



Make the power output more reasonable

 

The performance of this hybrid system in terms of power can be grasped by this "S400 HYBRID power characteristics chart".

The vertical axis is the torque and the horizontal axis is the engine speed. The red dotted line shows the torque output of the engine, the gray part is the torque supplied by the electric motor, and the green line shows the total output torque of the electric motor + engine. As can be seen from the graph, the total output torque is approximately smooth at different engine speeds; at low speeds, the electric motor intervenes significantly to supply more extra torque for city driving conditions.

It is understood that the S400 HYBRID will actively shut down the gasoline engine when the speed is below 15 km/h, but the active air tuning and directional assist will still be on, because these two systems are controlled by electronic system in this model. If you need to accelerate, the six-cylinder engine will be quickly awakened, steep and steady to raise the speed of the car, together with the instrument panel will clearly show the hybrid system work status, and remind the driver of the energy in the battery.
