What is the composition of the BYD Qin hybrid electric vehicle high voltage system?

18 years hybridBYD QinThe low-voltage battery is located on the left side of the front hood of the vehicle. The low-voltage battery of BYD Auto is generally located on the left side of the front hood of the vehicle, and it is very firmly fixed with fixing bolts. Its main role is when the engine is starting or running at low speed, due to the car generator.

If there is no electricity generation or the voltage is very low, the electric energy required by the starter, ignition system and electrical equipment in the car is all supplied by the battery.

Features of the 18-year hybrid BYD Qin

The 18-year-old hybrid BYD Qin car is first of all fuel-efficient, using electric drive at low speeds, and using fuel when high-speed driving requires high power output, which reduces fuel consumption, is suitable for urban driving, and has explosive power.

Strong, fast acceleration without delay when using electric drive, low noise, no motor noise when electric drive, quiet and comfortable. In terms of power consumption, its performance is one of the few in the industry, and this car solves the problem of new energy vehicles.

Spontaneous combustion of batteries.

BYD Qin's hybrid car is OK.

The BYD Qin is the only DM II autonomous car in China that has European safety standards. Acceleration seconds, fuel consumption per 100 kilometers measured. The noise control adopts space capsule technology, the overall mold is Japan's Dihara, and the vehicle technology is provided by Daimler-Benz and BYD Auto after the joint venture.

It is also a personal opinion that the most cost-effective car at this stage (after subsidies).

In terms of appearance, Qin's production car maintains a high degree of similarity with the previously released concept version of the model, and many design elements with a high recognition rate have been retained one by one.

In terms of conventional power, Qin is equipped with a direct injection turbocharged engine in the cylinder consistent with Surui, with a maximum power of 154 horsepower 5200prm and a maximum torque of 240 Nm 1750-3500rpm In terms of electric engine, Qin is equipped with a high-voltage, high-speed and high-power "three high" motor, which can drive 50 kilometers with 10 kWh of electricity.

The Qin uses DMIL dual-mode technology, which allows owners to switch between EV (pure electric) and HEV (hybrid) modes.

BYD Qin

BYD Qin, a high-performance sedan independently developed by BYD Co., Ltd. (switching between pure electric and hybrid modes). Since its joint venture with Daimler of Germany, BYD's car-making process has been greatly improved.

As long as the power supply is shared, the three power supplies must be turned on at the same time to be able to supply power.

BYD Qin is BYD shares.

It is a high-performance sedan developed in-house dM II (which switches between pure electric and hybrid modes). Since with the German Daimler.

After the joint venture, BYD's car-making process has been greatly improved. Its acceleration of 100 kilometers per second made many riders amazed.

Principle. Generators can turn mechanical energy.

Converted into electrical energy, dry batteries can convert chemical energy into electrical energy. Dynamo. The battery itself is not charged, its poles have positive and negative charges, and the voltage is generated by the positive and negative charges (the electric vertical spike flow is formed by the directional movement of the charge under the action of voltage), and the charge conductor is inherently there, and the voltage is only needed to generate the current.

When the two poles of the battery are connected to the conductor, the positive and negative charges are released in order to generate current, and when the charge is dissipated, the load flow (voltage) is eliminated. Dry batteries, etc., are called power supplies. through transformers and rectifiers.

Put the alternating current. It becomes direct current.

The device is called the power supply rectifier power supply. The electronic device that can provide a signal is called a signal source.

The transistor can amplify the signal sent from the front, and then transmit the amplified signal to the circuit behind. The transistor can also be regarded as a signal source for the rest of the circuit behind it. Rectifier power supply and signal source are sometimes called power supply sources.

I'm just a porter, Qin's low-voltage system is provided by three clerks, namely: 12V iron battery, DC-DC, generator. In fact, it is of little significance for us to pay attention to this problem when we buy a car, as long as we tell Zen to start the car and attack the quality of the nai, it is easy to drive, and it is enough to worry about socks.

Use the three internal power supplies for power, and then you can look at its voltage transformer, you can know.

They are 12vLead-acid batteries, DC DC, generator.

BYD Qin is BYD shares.

Self-developed DM II (in pure electric and hybrid.

Switching between the two modes) is a high-performance sedan. Since punching the German Daimler with a pin stool.

After the joint venture, BYD's car-making process has been greatly improved. Its acceleration of 100 kilometers per second made many riders amazed.

Although there are many types of vehicles, the structure is similar. This should be said to be the credit of standardization, but also the need for large-scale production lines. With the development of society, the progress of science and technology and the change of demand, the shape of railway vehicles has begun to change, especially the passenger car is no longer the same old face.

However, their basic structure has not changed significantly, but the specific parts have been more scientifically advanced structural design.

Generally speaking, the basic structure of the vehicle is composed of five parts: the car body, the undercarriage, the running part, the coupler buffer device and the braking device.

The body is the part of the vehicle that is used to carry goods or passengers, and is the foundation on which it is installed and connected to other components of the vehicle. The body of the early vehicles was mainly made of wood, supplemented by steel plates, bow rods, etc. In modern times, the car body is mainly steel structure or light metal structure.

New energy (abbreviation: NE), also known as non-leased conventional energy, refers to various forms of energy sources other than traditional energy, and generally leads are renewable energy sources that are developed and utilized on the basis of new technologies, such as solar energy, geothermal energy, wind energy, marine energy, biomass energy and nuclear fusion energy.

The differences between the four modes of BYD Qin are as follows.

1. EV+ECO mode is a pure electric energy-saving mode, in this mode, the car uses electric energy to drive, and the driving computer adjusts the engine parameters, so that the engine efficiency is reduced, so as to save energy, and the vehicle is the most energy-saving in this mode.

2. EV+SPORT mode is a pure electric sports mode. In this mode, electrical energy is used to provide energy, and the trip computer adjusts the engine parameters to improve engine efficiency, thereby improving the vehicle's performance.

3. HEV+ECO mode is the energy-saving mode of hybrid mode, the vehicle uses two hybrid types of electric energy and fuel, and the driving computer adjusts the engine parameters to reduce the engine efficiency and save energy.

4. HEV+SPORT is the operation mode of the vehicle hybrid mode, the vehicle uses two hybrid types of electric energy and fuel, and the driving computer adjusts the engine parameters to increase the energy consumption of the vehicle and enhance the horsepower, and the energy consumption in this mode is the largest.
