What problems do you need to pay attention to when driving a hybrid car in winter?

New energy hybrid electric vehicles.

The power of ** is the battery, the battery capacity in a low temperature environment.

The capacitance is much lower than that at room temperature, and many electric vehicles will not catch fire in the cold season. This is mainly due to the low capacity of the battery and the lack of power supply, in the winter season, it is recommended that the majority of car owners check whether the battery has enough electrolyte, if it is insufficient, the electrolyte of the battery should be replenished in time to adjust the specific gravity of the electrolyte of the battery; At the same time, it is necessary to check whether there is leakage of electrolyte or deformation, if there is leakage or deformation, it is best to go to the maintenance station to solve it. And hybrid cars.

It is often necessary to warm up the car when starting in winter. Otherwise, it is easy to damage the engine. At the same time, try to avoid behaviors that consume more power such as rapid acceleration and high-speed driving, and use more kinetic energy systems of the vehicle to reduce the number of times you step on the brakes.

There are many kinds of modern hybrid vehicles, generally referring to gasoline hybrid vehicles, which combine batteries and electric motors on the basis of conventional gasoline engines, do not need to be charged, and the role is mainly to replace the gasoline engine when necessary, so that the gasoline engine can always be kept near the most economical speed, as well as the first kinetic energy. One of the most successful is Toyota's hybrid power system, which has sold more than 10 million units worldwide, and the representative model Prius, planetary gears instead of gearboxes, is ahead of the world. I drive the third generation, and the fuel consumption in the city is about 5 liters.

The advantage is that it has a long endurance, 40 liters of oil runs more than 900 kilometers, fuel saving, comfortable driving, and as for power, the economy mode is equivalent to the logo 307, and the power mode is equivalent to the flag 307. The disadvantages are mainly in the battery, the first ten years are certainly fine, after ten years it began to have problems, in 2001 the Prius now 5% of users have changed the battery, the rest are still in normal use. This is approximately the battery failure rate.

The relatively popular BYD hybrid in China takes a different path, which is completely different from Toyota, with the battery increasing dozens of times, the electric motor being replaced with high power, and the gearbox being retained. So the weight of the body is huge. The advantage is that the acceleration performance is very good, better than ordinary vehicles, and better than electric vehicles, and can and must be charged every day, short-distance use, can achieve pure electric (some models), the cruising range is more than 50 kilometers, relatively long.

The disadvantages are also obvious, once the charged power is used up, the fuel consumption is huge, about 3 times that of the Prius, so the comprehensive fuel consumption will not be lower than the Prius in the case of daily charging, and then it is not suitable for running long distances, the performance is poor after the battery is exhausted, the fuel consumption is large, and the body is too heavy, and the control is not good. BYD and Prius are controversial, there are too many forums, and it is easy to find real car owners to understand, so there will be a more objective answer.

Summary. Dear, I'm glad to answer for you, hybrid does not need a hot car, and there is no need for a hot car whether it is a hybrid or a traditional fuel vehicle, unless a few models that have to be heated by the gearbox. Before the temperature is reached, poor oil injection atomization, unreasonable air-fuel ratio will lead to high and low idle speed and even stalling, and it is necessary to heat up the car in this era.

Dear, I'm glad to answer for you, hybrid doesn't need a hot car, and there is no need for a hot car, whether it is a hybrid or a traditional fuel vehicle, unless it is limited by a variable speedbox to a few models that have to be hot. Before the temperature is reached, the poor atomization of fuel injection and the unreasonable air-fuel ratio will lead to high and low idle speed and even stalling.

Hybrid refers to a technology that uses two different power sources in the vehicle power system, and currently focuses more on the hybrid of oil and electricity. It is a new energy vehicle technology that is different from traditional vehicles, and it is a widely used hybrid power system, and a number of small automotive products have been put on the market, which can be divided into series, parallel and hybrid three kinds according to the connection mode.

When buying a hybrid car, the first thing you need to pay attention to is the type of motor used in the hybrid car, because the biggest difference between a hybrid car and a fuel vehicle is that there will be an electric motor intervention, and you should understand the motor warranty policy of the rolling vehicle.

I think we need to pay attention to how the hybrid of this car is, whether the configuration is high, and how the accessories of the car are. Then it depends on whether this model is suitable for driving by yourself, and how large the size and spaciousness of the body are.

When buying a hybrid car, we need to pay attention to the fact that not all hybrid models can obtain the Beijing New Energy Index, and do not confuse gasoline-electric hybrid vehicles with plug-in hybrid models.

It is necessary to understand the type of motor used in hybrid vehicles, and the motor warranty policy; It is best to choose a wide range of battery operating temperature to ensure that the hybrid vehicle can run well in cold weather.

First of all, it is best to consider a hybrid model with a PT C heater, and secondly, it is better to choose a hybrid model with a wider operating temperature range of the battery pack. In this way, when the hybrid model encounters a cold winter, the activity of the power battery pack will not be so reduced, which can also ensure that the very dynamic model can have better performance in the cold winter.

We should pay attention to the quality and safety of the measurement, but also whether there is a certificate or not, and we should pay attention to the system configuration of the vehicle, these are very reasonable things.

Hybrids do not need to be hot in winter.

Hybrid cars do not need to be hot in winter, they start and go, the engine will start charging if the power is not enough, and the battery will not have any loss, and the battery basically has the same life as the engine.

As the price of hybrid vehicles has continued to rise in recent years, environmentally friendly models have attracted more attention. There has been a lot of discussion about the technical route of new energy vehicles, and the industry generally believes that the development of hybrid vehicles is more suitable for China's actual situation than the development of electric vehicles. Hybrid technology is a current market-oriented development trend due to the combination of the advantages of internal combustion engines and electric vehicles, which can significantly reduce emissions and reduce energy consumption.

Causes of hot cars

After the car has been parked for a long time, the oil in the engine flows back into the oil pan in the lower part of the engine. Therefore, when the engine is started after a long time without use, the upper part of the engine is in a state of lack of oil and lubrication. It takes about 10 seconds after the start of the oil pump to deliver the oil to the pistons, connecting rods and crankshafts of the engine, which need to be lubricated the most.

But even if you start the engine and hit the road immediately, as long as you don't slam on the accelerator and keep running at a low speed, the effect is the same as idling.

When the gear oil is cold, the gear oil flows to the lower half of the gearbox, and only when the car is driven will the gear oil at the bottom be lifted up due to the operation of the gear to lubricate the upper half. This is also the reason why most cars change gears jerkily when they are cold. The solution is not something that can be solved by in-situ hot cars.

Because the gearbox is hidden and there is no gear oil pump, only the engine is moving, and the rest of the car is not moving.

The top 10 tips for buying a hybrid car are as follows:

1. The handling is average

This can be regarded as a disadvantage or not, but owners of Honda CRV need to pay attention to the fact that because its product strength mainly pursues comfort and large space, the handling is almost not taken into account, and it is important to pay attention to controlling the speed of the vehicle when driving in corners or rainy days.

2. Backward appearance

Backwardness here does not refer to the design language, after all, whether it looks good or not is a matter of opinion. The lag I want to say is the functional backwardness in terms of appearance, for example, the large impact area leads to excessive wind resistance, which makes the sound of wind noise heard in the car more obvious.

3. The steering wheel has an obvious electronic taste

We all know that the current vehicle steering system without exception adopts electric power steering, and the rotational damping and re-centering force of the steering wheel can be adjusted, and there is a positive relationship with the vehicle's driving speed and steering angle. The Honda CRV steers slightly lightly and unevenly.

4. Both pedals are lighter

The Honda CRV does not have a tight operating feedback regardless of the accelerator pedal or brake pedal, and there is a sense of emptiness about the pedal control, and even the judgment of the pedal depth and pedal position when the sole of the driver's shoe is too thick.

5. The emulsion of engine oil is intensified

This incident may be Honda's biggest quality problem in the Chinese market in the past decade, and the quality problem covers a super wide area, and its reputation has seriously declined.

6. The steering wheel adaptation range is small

If you prefer a low, rear-back driving position, it can be difficult to adjust to the right steering wheel position. If you are a tall driver, you will feel like driving with the steering wheel on your shoulder, just like driving a bus.

7. The quietness of the carriage is low

In fact, the models under the Honleak Sedan seem to be noisier than the models of the same class, and of course the CRV is no exception. Wind noise and road noise are particularly noticeable, and the engine sound can be suppressed in the case of hybrid models, and the engine sound is particularly noticeable in the case of a car equipped with a turbocharged engine.

8. The rapid acceleration effect of hybrid models is slow

After stepping on the accelerator, the power battery reduces the output of electric energy to the drive motor, and gives part of the electric energy to the starter-generator motor to start the engine, and then the engine charges the power battery through the start-generation integrated motor on the one hand, and drives the vehicle to accelerate on the other hand. In this case, the response is a little slow and not timely enough, and it should continue to be optimized better.

9. There is still room for improvement in the suspension system

Driving a Honda CRV over a fine road surface or a relatively small speed bump, the suspension system seems to be transmitted into the cabin without much filtering, which is not particularly comfortable.

10. The field of view of the rearview mirror is narrow

The rearview mirror of the Honda CRV is relatively high and relatively forward, which not only has a small range of vision in the rearview mirror, but also blocks the left front driving vision to a certain extent.

There are the following reasons why the car cannot start: a. No oil. Two. Power. Three. No air intake.

Let's analyze these four items approximately:

One. No oil.

The reasons for the failure are:1The oil pump relay is not working well. 2.The oil pump is not working well. 3.Out of gas.

Fault Detection: 1Detection of oil pump relays:

Turn on the key switch and don't hit the motor, you will hear a click, which means that the relay is working properly! If there is a continuous clicking sound, check whether the tie wire is loose. If the relay is judged to be damaged, the light relay can be interchanged with the oil pump relay.

Drive to the repair shop and buy a new relay.

2.Detection of oil pump: Generally, it is checked with an oil pressure gauge, because it is self-excluded.

There is no oil pressure gauge! The easiest way to do this is to remove the tubing and turn on the key switch on the position. Do not start the motor.

If the oil pipe is injected, it means that the oil pump is normal. On the contrary, it is not normal.

Two. Power. Cause of failure:

1.The head of the battery pile is loose. 2.

The high-voltage ignition coil is damaged. 3.The cylinder line is damaged.

4.Whether the starting relay is plugged in properly or not, it is damaged. 5.

Whether the insurance is burned out. 6.Whether the motor is working properly.

7.Whether the main output cable of the computer case is loose.

Fault Detection: 1Detection of loose battery pile head: observe whether the instrument is displayed, if the whole car has no electricity, open the hood, and observe whether the battery pile head connection is loose and oxidized. Loosen it with a wrench, and pour boiling water on the pile head for oxidation.

2.Detection of ignition coil: You can use a multimeter to check the resistance value of its primary and secondary coils, which should be within the conforming range, and the secondary resistance should be larger than the primary resistance!

But that's not sure if it's in good condition! Unplug the cylinder wire, observe it for flashover, and see if there is any leakage in the insulation! The jumping fire should be blue, and the sparks are thick and long!

3.Detection and grinding of steel wire: check the resistance value with a multimeter, which should be within the load range. Unplug the cylinder cord and observe it for a flashover. Or skip the fire and replace.

4.Detection of starting relay: There is a problem with the general relay, and there is no response when hitting the motor. Plug and unplug the relay again to see if it starts normally! Replace the relay or short-circuit.

5.Detection of the fuse: Open the fuse and observe whether the fuse indicator is normal and whether the fuse is burned. Replace the fuse.

6.Motor detection: mainly listen to whether the sound of the motor is normal. If the carbon brush of the motor is severely worn, it can be temporarily activated by hitting the motor with a hammer. Go back to the repair shop for replacement.

7.Whether the main output line of the computer box is loose: check whether the plug-in of the computer box and its wiring and each sensor is loose. Fastening is recommended.

Three, no air intake.

Cause of failure: Damage to the eccentric wheel and wear of the eccentric shaft, resulting in the intake and exhaust valves cannot be opened and closed.

Plug-in hybrid vehicles can be used in non-pure electric mode in winter.

For example, the principle of "charging as you go" is adopted for the vehicle, and the vehicle is charged immediately after use, because the battery temperature is relatively high at this time, which can improve the charging efficiency. In addition, we will also make some plans for travel in advance to avoid insufficient mileage, and even dare not turn on the air conditioner to heat up when traveling.

Because of the design of pure electric vehicles, the use of air conditioning for heating in winter is quite power-consuming, and on the other hand, the slow use of air conditioning to produce hot air is also an aspect, which will mainly affect the battery life, but if it is said that plug-in hybrid vehicles will not appear this situation.

Plug-in hybrid vehicles:

In the case of plug-in hybrid models, the engine and electric motor are two sets of relatively independent operating branches, and there is no need to worry about the cruising range in winter, and the engine can be used to drive the vehicle through the engine to drive the gearbox in winter.

During the driving process, the water temperature of the engine can be used for heating, so there is no need to worry about travel like a pure electric car. Whether you use a plug-in hybrid or a pure electric vehicle in winter, regular maintenance is the most important thing when winter comes.
