18650 battery 3500mah lithium

Hydrogen refueling stations become a stumbling block. Introducing Hyundai's fourth-generation 18650 battery 3500mah lithium technology

Hydrogen 18650 battery 3500mah lithium technology is not a problem. The biggest obstacle is the construction of hydrogen refueling stations. The region with the most hydrogen refueling stations in the world is California, USA. Looking at the domestic market, there is no commercial hydrogen refueling station. The development of hydrogen 18650 battery 3500mah lithium lithium batteries in the field of domestic passenger cars is almost stagnant. Only SAIC Roewe has launched hydrogen 18650 battery 3500mah lithium lithium battery vehicles.

A while ago, CLARITY 18650 battery 3500mah lithium lithium battery vehicles were very popular in Japan and even the United States. Its maximum range can reach 750km, which is really surprising (there should be a finger-eating expression here). However, Hyundai's hydrogen 18650 battery 3500mah lithium lithium battery, which was announced as early as 2013, is not so interesting. The overall design of the current ix35FCV 18650 battery 3500mah lithium lithium battery vehicle cannot keep up with the pace of the times, and the huge hydrogen storage tank placed in the trunk is often complained.

At this Shanghai Auto Show, Hyundai displayed the fourth-generation hydrogen 18650 battery 3500mah lithium technology. Is this hydrogen 18650 battery 3500mah lithium technology improved compared to the previous system?

Overview of the fourth-generation hydrogen 18650 battery 3500mah lithium lithium battery

Hyundai announced the next-generation 18650 battery 3500mah lithium lithium battery plan at the 2017 Geneva Motor Show, and it is expected that the models equipped with the fourth-generation 18650 battery 3500mah lithium lithium battery technology will be launched in 2018. Seeing that Honda and Toyota have designed a car specifically for 18650 battery 3500mah lithium lithium batteries, Hyundai believes that it is also necessary to create a 18650 battery 3500mah lithium lithium battery-specific model. This Shanghai Auto Show brought the FEFuelCell concept car that has been unveiled globally at the Geneva Auto Show.

The fourth-generation hydrogen 18650 battery 3500mah lithium lithium battery technology is based on the ix35FCV technology and improves it, increasing the power efficiency by 10%, the power density of the 18650 battery 3500mah lithium lithium battery by 30%, and the weight of the vehicle by 20%, thereby further improving the cruising range. In the future, the cruising range will exceed the 750 kilometers of Honda CLARITY and reach 800 kilometers.

Hydrogen storage system improves storage efficiency

The storage space of the ix35FCV has always been criticized by users. As a compact SUV, its storage space is as small as that of a small car, because its rear trunk is equipped with two large hydrogen tanks. This time, Hyundai has carried out a large-scale upgrade and transformation of the hydrogen storage system, changing the size and location of the hydrogen storage tanks.

The hydrogen storage tanks have been reduced from two large and one small to three tanks of the same size and shape. In the future, there will be dedicated models equipped with this system, and there is no need to consider the body space layout. At the same time, the size of Hyundai's hydrogen fuel-powered lithium battery car in the future will be larger than the current ix35FCV, so the three hydrogen storage tanks will be installed at the bottom of the car body, that is, under the seat. This ensures that the luggage space is as large as that of a fuel vehicle.

The hydrogen storage tank will be reinforced with a new high-strength carbon fiber layer inside and reinforced with a tempered fiber layer on the outer surface. As a result, the overall hydrogen storage tank is 10% lighter than the ix35FCV, and the storage efficiency of hydrogen fuel is increased by 25% compared to the ix35FCV, resulting in a significant increase in cruising range.

The hydrogen storage system will use a two-stage valve to release hydrogen. The high-pressure hydrogen valve controls the switch of hydrogen supply, and the pressure reducing valve reduces the high-pressure hydrogen to a low-pressure state to meet the expected pressure of the fuel reactor. The overall hydrogen storage system achieves the increase in cruising range and the balance of the rear space by expanding the volume and changing the shape.

Improved safety performance

Due to the change in the position of the hydrogen storage tank, it is more likely to be dangerous when it is located at the bottom of the vehicle body. The hydrogen storage tank must be protected, and multiple detections, hydrogen circulation tests, fire tests, impact damage tests, extreme temperature and pressure circulation tests, penetration tests, chemical exposure tests, etc. must be carried out.

When a fire occurs in the vehicle, an emergency release device is used to ensure the safety of compressed hydrogen. At the same time, the gas storage tank is made of refractory materials and can withstand the test of fire for a period of time. The interior of the hydrogen storage tank uses an internal liner with a highly isolated gas, and a single injection port effectively prevents injection leakage. The valve and nozzle are enhanced to ensure the airtightness of the hydrogen storage tank.

In the face of collision, the impact protector used inside the hydrogen storage tank can interrupt the supply of hydrogen when the acceleration is too large to prevent explosion. The exterior uses a tempered fiber layer, which can effectively block impact and collision, and the interior is also reinforced with tempered fiber.

Reactor power density is improved

The electric power system adopts a highly integrated solution. The fuel-powered lithium battery reactor, operating equipment and electronic power transmission system are highly integrated together. The overall size is the same as that of an internal combustion engine, which is very suitable for placement in the engine compartment. It is very suitable for mass processing. In the future, the price of fuel-powered lithium battery vehicles will drop significantly.

Hyundai's renewed efforts in hydrogen fuel-powered lithium battery technology are clearly stimulated by Toyota and Honda. After all, the ix35FCV launched in 2013 is a bit behind the times. The overall cruising range has been greatly improved. At the same time, the power of the fuel-powered lithium battery reactor has also been improved. The overall performance of the fourth-generation hydrogen fuel-powered lithium battery has been improved a lot. The cruising range is not much different from that of internal combustion vehicles, which can fully meet daily use.

Hydrogen fuel-powered lithium battery technology is not a problem. The biggest obstacle is the construction of hydrogen refueling stations. The region with the most hydrogen refueling stations in the world is California, USA. Looking at the domestic market, there is no commercial hydrogen refueling station. The development of hydrogen fuel-powered lithium batteries in the domestic passenger car field is almost stagnant. Only SAIC Roewe has launched hydrogen fuel-powered lithium battery vehicles.

It is still unknown which energy will be dominant in the future. However, many brands have already stepped up their R&D efforts instead of just focusing on pure electric vehicles. Should domestic brands go one step further? I heard that Foton has started to take action.
