Huawei published new smart car charging technology patent to improve charging efficiency

Published

on


On June 29, Huawei has released a new patent entitled “a charging control device, method, and electric vehicle” with publication number CN113056387A in China. According to the Chinese intellectual property database, this patent was applied on April 23, 2020.

Moving with time, Huawei is continuously innovating new methods and devices and securing them in the form of patents in order to become the top smart vehicle technology supplier in the automobile industry.

Previously, the Chinese tech giant has patented several new ideas in the field of electric vehicles such as wireless charging parking space recommendations, charge one electric car from another, and more.

The patent documents disclose a charging control device, method, and electric vehicle including a signal processing module and management module.

Signal processing module:

A signal processing module used to receive the first signal sent by the power supply device, the control guide. According to the first control signal, it sends a high-level signal of the target duration to the management module.

Management module:

The management module is configured to wake up the battery management system after the duration of the received electrical signal reaches the target duration.

Furthermore, with this charging control device, even if the power is turned on again after a power failure during the charging process, there is no need to re-plug the charging gun or restart the electric vehicle charging pile at the charging port.

The charging control device can pass the high level of the target duration as long as it receives any CP signal, first, we need the battery management system to continue charging.

Huawei Battery Charging Technology

Recently, a Huawei patent entitled “Solar Cells and Their Preparation Methods, Smart Glasses, and Electronic Equipment” got the approval of the Chinese Intelectual Property Patent Database. On 21st September, Huawei has publishes this solar battery patent with the publication number CN113421977A in China. Meanwhile, it was applied back on 26th May this year.

The patent embodies an arrangement that includes a solar cell, smart glasses, and the main housing electronic device. Furthermore, the method works to reduce the resistance impact caused by the thin film when the battery size expands.

This solar battery patent designed by Huawei will be appropriate for large-area solar cell applications. The method will be more efficient and the cells will provide long-time backup giving a convenient operation.

  1. The first conductive layer and the second conductive layer are laminated and arranged on both sides of a functional layer.
  2. The functional layer is used to consume light and generate a photocurrent and gradually transmit the current in the first and second conductive layers.
  3. One surface of the first conductive grid is in contact with one surface of the first conductive layer maintaining a distance with the functional layer
  4. Furthermore, the first conductive grid provides the photocurrent to the electronic device.
  5. The second conductive grid is fixed in the functional layer in sidewise contact with the second conductive layer.
  6. At last, the second conductive grid also transmits the photocurrent to the electronic device giving it double efficiency.

Previous Battery Patent:

Last month, Huawei shared the vehicle-breaking patent that is able to control power recovery after analyzing battery state. The patent entitled “Vehicle Braking Method, Device and Electronic Equipment” has been published with the declaration number CN113302078A in China on August 24th. (Read More Here)

Huawei to bring new VR head mounted technology: Patent

Published

on

Huawei VR Glasses

Huawei is working on new a new VR technology, it’ll add more advanced devices to the company’s collection. In this line, the company has released a new patent, which recently gets the approval of the Chinese Intellectual Property Database. It’ll be a lightweight VR head unit and will release the pressure while wearing the device.

As per the information, Huawei applied for a patent entitled “a head-mounted display and virtual reality system” back in March 2019. Now, it has passed the examination phase and the company has published it with the publication number CN111694152B in China on  14 September 2021.

The patent abstract shows, the described head-mounted display will make the users interact with virtual reality. Furthermore, during the time wearing the head unit users won’t feel much pressure and can enjoy the work with more comfort.

Huawei VR Technology Patent Description:

The application describes that the device will have a main head unit module, two magnetic arrangements, and integrated technologies. Furthermore, the first magnet won’t be dependent on the head unit body. Meanwhile, the second magnet structure will be used for opposite forces.

Thus, this magnetic arrangement will provide the head modules a skyward magnetic force. The technology will be in the virtual reality applications that will provide less pressure.

In June 2021 Huawei Headheld and HeadPositioner (VR) have passed Bluetooth SIG certification with model numbers Par-CG013 and Par-CG012 respectively. Both models will work on Bluetooth 5.0. However, the company hasn’t revealed any further information yet.

Huawei Rollable Phone

In the past, we’ve seen a number of new Huawei patents and designs about rollable phones. Compared to the foldable design, the rollable phone extends outwards from within a regular phone size.

However, new patents continue to appear. In the latest edition, LetsGoDigital has found a new rollable phone design that was filed in February 2020 at World Intellectual Property Organization (WIPO). The patent is titled ‘An apparatus and a method for a controllable foldable display with haptic and sound effect’. The 38-page documentation was approved and released on September 2, 2021.

Huawei Rollable Phone with Gestures:

Aside from its design, the new patent has new hand gestures called Freehand Gesture Control. To conduct such controls, a virtual slider is shown on the screen.

The extended display will be accompanied by haptic feedback (screen vibration) and a sound effect. The advantage of this display extension sound compensates for the noise generated during the rolling process.

Not only that, there are plenty of hand movements that users can make to enjoy a seamless gestures movement across this futuristic device. These includes:

  • Swipe above to roll in or out
  • A movement to the right to unroll or left to retract

Manage Roll Speed:

The gestures are so advanced, they could even allow users to manage the speed of the rollout and roll back-in process detected by the use of the finger count and is detected by a motion sensor or a camera module. This is quite interesting and is surely futuristic to see that happen.

Realistic Concept Video:

Huawei Mate Rollable appears to be a normal smartphone at first sight. But it has the ability to expand into tablet-like big screen size. Unlike the foldable, the rollable smartphone can increase or decrease the area of its display by rolling in and out.

The phone’s front design looks identical to any regular smartphone, yet it can expand to a large tablet at an instance. Unlike a foldable device, the Rollable phone can expand outwards by taking a limited space. Through this mechanism, a 6.5-inch panel can expand to an 11-inch screen.
