Seemingly simple, complicated, talking about how hybrid systems work

At this stage, many automobile brands are vigorously promoting their electric vehicles and hybrid products. It can be seen that the way of using electric energy as a source of kinetic energy does have an irreplaceable advantage, except for reducing the economic pressure in the process of using the vehicle, regardless of Emissions or power also have inherent advantages.

However, many car owners may not have understood. In fact, electric vehicles and hybrid vehicles are not as imaginary. They convert electric energy into kinetic energy, but they need to go through a series of processes, but they are ignored.

Whether it's an electric car or a hybrid car, batteries are an indispensable part of the battery, but don't forget that both are equipped with electric motors.

First of all, we take the hybrid model as an example. The electric motor can be simply regarded as the second engine of the pure diesel engine. It is still the core of power generation.

At the same time, as an important part of generating power, lithium-ion battery packs are the second source of power, playing the role of the fuel tank of diesel locomotives.

Under normal circumstances, hybrid vehicles will be equipped with a kinetic energy recovery system. In many people's eyes, it is nothing more than a process of converting kinetic energy into electrical energy, but it is not so simple.

When the driver steps on the brake pedal, the brake caliper will bite the brake disc, and part of the brake horsepower will be converted into heat.

Since the power requirement is not high when the vehicle is braking, the kinetic energy recovery system begins to intervene during this time. Taking the flywheel structure as an example, that is, the vehicle drive shaft drives the flywheel rotation in the kinetic energy recovery system. This provides kinetic energy to the kinetic energy recovery system.

At this time, since the flywheel structure of the kinetic energy recovery system cannot store kinetic energy, if it is not used for power output, it needs to be released. For this reason, the kinetic energy recovery system converts kinetic energy into electrical energy and stores it in the battery pack.

Although the battery is the source of electrical energy, the battery itself cannot store electrical energy. The electrolyte inside the battery can only store chemical energy, and the electrical energy in the kinetic energy recovery system is further converted into chemical energy, which is stored inside the battery pack.

When the power needs to be released, the conversion method is basically the opposite of the kinetic energy recovery method, which converts chemical energy into electrical energy and then converts the electrical energy into kinetic energy.

The above process is simply a process of how kinetic energy is transformed. The kinetic energy conversion of a hybrid vehicle is not as simple as imagined. There are still many ways to convert it. For example, when the engine is running, part of the kinetic energy is also converted into electric energy and stored in Among the lithium-ion battery packs.

Since the kinetic energy recovery system and the flywheel group are in working state most of the time, when the driver needs to accelerate, the part of the flywheel and kinetic energy recovery system that has not been converted into chemical energy will be converted back to kinetic energy by the electric motor for vehicle acceleration.

In fact, when designing and developing a hybrid car, it is not just as simple as adding a system to the engine of an internal combustion engine. It needs to add a whole system in a limited space. The center of gravity and dynamic characteristics of the vehicle need to be redesigned and test.

Strictly speaking, the introduction of a hybrid car based on a pure internal combustion engine power model is not much different from the re-development of a new model. It needs to be subject to many space constraints, and in the design and test process, the internal combustion engine needs to be considered. Part of the compatibility with the electric drive part, not only the power structure is more complicated, but also the electronic program is extremely cumbersome.
