How to Determine Battery Performance?
Advances in battery technology have contributed greatly to the changing technological environment around us. Today, competition between different power battery technologies is at the forefront of various applications.
But at the same time, the safety of the battery has also spurred everyone’s sensitive nerves. In the first half of this year, many new energy vehicles such as Tesla, Weilai, and BYD have had many spontaneous combustion incidents.
The above shows that the performance evaluation of the battery is a comprehensive indicator system, and the most important factor in this indicator system is not the energy density, but the safety.
DENSITY or SAFETY?
According to some relevant research data, there are two main reasons for the fire alarm of the power battery.
The proportion of the internal short circuit causing the fire accident is about 35%.
The proportion of the battery fire caused by the mechanical external force such as collision is about 18 %; 16% of fire accidents are related to the charging process, especially at the end of charging and overcharging, which is more likely to cause safety problems.
With the increase of system energy density, the focus on the safety of power batteries is no longer limited to the level of the unit. “In the test phase, the safety issues that everyone cares about have transitioned from the single level to the multi-level system evaluation stage. The security at the physical level is not an absolute security concept, but a relatively safe concept.”

The 2019 Hyperloop Super High Speed Rail Race officially began in April. For Super High Iron Powder, this is a passionate summer!
Super High Speed Rail The Hyperloop is a pipeline-based sub-supersonic transport system super-loop train, initiated by Tesla’s founder Elon Musk. The Hyperloop train is mainly used in a vacuum-like pipeline. The high-rate battery is used to project the train like a bullet, and then the battery is gradually accelerated to a fixed speed, which is estimated to reach 1120kg/h in the future. The battery configuration is also like Tesla, where many small battery packs are placed to form part of the power system (theoretically solar powered).
Super high-speed rail Hyperloop
The entire train project is still in development, and every year there is the Hyperloop Pod Competition organized by Space X to find better train solutions. Every year, many universities are investigating, looking for suitable batteries, testing and participating in competitions.
Swissloop (Switzerland) college student team
In the past year, the team from the Netherlands used the high-rate battery provided by GREPOW as the special battery for the competition, and achieved the second place. Now that Hyperloop is launching in the new season, the Dutch team also said that the new season will continue to cooperate fully with GREPOW. With the GREPOW high-powered battery, we still provide them with upgraded batteries, and look forward to this time.
The GREPOW high-rate batteries reappeared in the eyes of the major teams, and the SwissSwiss University team from Switzerland also selected our high rate battery. This means that the GREPOW cell is moving towards internationalization and specialization.
You may not know that the Hyperloop event specifies the requirements of the dedicated machine. The endurance, equipment stability, frame rate fluctuation control, temperature control, network stability, precision operation, etc. all need to reach extremely high standards.
And our GREPOW battery can become the special battery for the Hyperloop team, and more of it is based on its powerful hardware configuration and special optimization for power.
This time, GREPOW teamed up with the Hyperloop team to rely on excellent product quality and a more appropriate brand philosophy. These reasons made our cooperation come true. Nowadays, the overall better GREPOW high-rate battery is in the world. I wonder if it will become the “new weapon” of Hyperloop professional players again? Let us wait and see!

In addition to traditional shoe enterprises, companies in the field of smart shoes, such as Nike, Adi, Li Ning. There are also startups and Internet giants such as Tencent, Baidu, and Xiaomi. It’s an eye-opening market for companies to compete in, and
Children's smart shoes, to build an all-round protection network that protects children's safety and health. Dynamically push the child’s real-time location to jointly monitor the child’s safety and health.
Baidu, 361 — children positioning shoes
In 2015, 361 and Baidu launched four smart children’s shoe products, with the main function of anti-loss. Intelligent children’s shoes introduced Baidu Hawkeye technology, with Baidu map LBS platform open service, with positioning monitoring function, Baidu Hawkeye’s WIFI positioning function fundamentally solves the problem that other children’s anti-lost products cannot be located indoors, sweeping away blind spots. When the child inadvertently leaves the scope of supervision, the first time will be reminded.
This wearable battery uses wireless charging technology. The wearable battery can be charged simply by placing the shoe on a specific charging pad.
In addition, 361 smart children’s shoes will also combine Baidu trajectory monitoring with Baidu’s big data, which can monitor the child's physical condition at any time, and upload the data to Baidu Health Cloud daily, according to the scientific plan of the Million Children's Health Database in Health Cloud. The child is tailored to the most professional health guidance.
Li Ning, Tencent – QQ
In 2016, Li Ning teamed up with Tencent QQ IOT to launch a children's smart running shoe. The built-in Bluetooth and chip are sealed inside the sole and can be bound to the parent’s mobile QQ before use. By locating the location of the mobile phone QQ user and indirectly obtaining the approximate location of the lost child, the child is found lost and the child is retrieved.
The biggest highlight of this product is that its wearable battery does not need to be charged for half a year, and it can maintain the duration of more than half a year under the premise of achieving the positioning function.
Its built-in has a large number of QQ user bases, using low-power Bluetooth so that the shoes will broadcast a unique Bluetooth signal to the surrounding. In the mobile phone QQ, users who have opened the “Join the search for lost children project” and turned on the Bluetooth option have felt these signals when approaching these smart shoes.
Looking forward to the future
In view of the fact that the traditional footwear industry is already saturated, “transformation and
Other wearable battery requirements, including battery life, capacity, etc., can be met. The wearable battery produced by Grepow
It is believed that with the continuous accumulation of market technology and the completion of the ecological layout, more smart products with innovative and technological charm will emerge in the near future, which will become the fuse of the next round of enterprise transformation.
