BYD is the world's leading manufacturer of batteries, especially for mobile phones. In addition, a BYD subsidiary is one of the largest automobile manufacturers in China. An assembly plant was opened in California in 2014 for the BYD ebus battery bus. In 2010, the company was named the best-performing technology company in the world by the US business magazine Bloomberg Businessweek. “BYD” stands for “Build your dreams”.

The company was founded in Shenzhen in 1995 by chemist Wang Chuanfu as a small factory with 20 employees. Initially, only rechargeable batteries were produced, which competed with the imported products from Sony and Sanyo, which dominated the market at the time.

Industrial robots were only used in the production of batteries from 2011. Through a very detailed and precise description of the workflow, the process sections in production could be reduced so much that even young people with little or even no professional qualifications were hired. This allowed semi-automatic production of batteries that were of equivalent quality to the products manufactured by industrial robots: However, due to low wages, which were significantly lower than those in Japan, they could be offered at a much lower price. However, BYD is now also using industrial robots on a large scale.

The Chinese government justified its low wage policy by saying that it could create permanent jobs for millions of young people. These people were often unskilled and moved from the countryside to the cities as China urbanized. The government also saw this as an opportunity to secure exports sustainably. From a Western perspective, however, this policy was criticized primarily because of the tiring, monotonous task performance, the high workload and the lack of further training opportunities for the workers.

Cheap manufacturing costs and high import tariffs on foreign goods in China have helped make BYD the world's largest manufacturer of rechargeable batteries since 2000. In addition, the company has the largest market share in sales of nickel-cadmium accumulators as well as batteries, chargers and keyboards for mobile phones and is the main supplier to major manufacturers such as Nokia, Motorola, Samsung, Sony Ericsson, Kyocera and Huawei.

In 2003, the company bought the ailing Xian Qinhuan Automobile and entered the automobile business; Since then, the production branch and the vehicles have been operating under the name BYD Auto Co. Ltd. The company decided against the quicker route of using licensed buildings from global corporations and instead relied on its own developments. By 2010, over 500,000 vehicles had already been produced. Today BYD Auto is one of the largest automobile manufacturers in China.

At the beginning of 2010, the company continues its activities in the field of environmental technology; for example, the production of solar farms and LED lighting technology for street lighting as well as battery-based electricity storage systems, which are also marketed in Germany. In January 2012, BYD commissioned (according to its own statements) the world's largest battery storage power plant with 36 megawatt hours.

Short version:

Founded in February 1995 and listed on the Hong Kong Stock Exchange on July 31, 2002, BYD Co Ltd began as a rechargeable battery manufacturer competing in the Chinese market with Japanese imports.

In 2022, a news report claimed that BYD has overtaken Tesla for the most electric vehicles sold worldwide. This claim is based on BYD sales figures, which include more than 300,000 plug-in hybrid vehicles sold in the first six months of 2022. Plug-in hybrids with combustion engines are not fully electric vehicles.

Early growth

BYD grew rapidly and within ten years captured more than half of the global mobile phone battery market and became the largest Chinese manufacturer (and one of the top four in the world) of all types of rechargeable batteries. BYD topped the 2010 Bloomberg Businessweek Tech 100 list, a list of large, fast-growing technology companies. Replacing machine labor with cheap, local labor lowered costs, and the company began expanding beyond batteries, adding automotive and cell phone components.

Motor vehicles

A year after the acquisition of Tsinchuan Automobile Co Ltd in 2002, BYD Automobile Co Ltd was founded. One of many Chinese automobile manufacturers, it was the sixth largest company in terms of sales volume in 2010. On April 3, 2022, BYD announced its intention to stop producing internal combustion engine vehicles and focus solely on electric vehicles.

Rail transport – Skyrail Monorail

In 2016, BYD unveiled a working monorail prototype marketed under the name “Skyrail” and announced it would enter the global rail transportation market. The first public Skyrail route opened as a 9.7 km loop at the Yinchuan Flower Exhibition in 2018. Since then, BYD has begun construction on a number of systems around the world, including the Guang'an Metro and Guilin Metro in China, Line 17 in São Paulo, and SkyRail Bahia, both in Brazil. BYD is also part of a consortium that won a pre-development contract to build a monorail from the San Fernando Valley to LAX over the Sepulveda Pass in Los Angeles.

Rubber-tired tram

BYD also has a rubber-tired tram product known as the SkyShuttle. The rubber-tired Bishan tram in Chongqing is in operation.

Mobile phone components

In the early 2000s, the BYD product range was expanded to include components for mobile phones. However, this division, BYD Electronic, was spun off in 2007.

The new generation of electricity storage is smaller, cheaper and more powerful than its predecessors. These innovations will revolutionize the energy market and fundamentally change the way we consume and generate our electricity.

New developments in electricity storage include lithium-ion batteries, which are now used in many households and companies. These batteries are much smaller and lighter than conventional lead batteries and have a significantly higher energy density. This means they can store more electricity while taking up less weight and space.

Lithium-ion batteries are also much cheaper to produce than lead-acid batteries. Lithium-ion battery prices have fallen sharply in recent years as the technology continues to improve. Experts expect prices to continue to fall, meaning lithium-ion batteries will become increasingly attractive to consumers and businesses.

The improved technology of lithium-ion batteries has also led to an increasing demand for these batteries. In recent years, more and more electric vehicles powered by lithium-ion batteries have been sold. More and more companies are also relying on lithium-ion batteries to cover their electricity needs. This is particularly the case if they do not have access to a regular power grid or their power grid is unreliable.

However, lithium-ion batteries are not the only new developments in electricity storage. There are also a number of other new technologies that could revolutionize the energy market. These include redox flow batteries, supercapacitors and powerwalls.

Redoxflow batteries are a further development of lithium-ion batteries. They have an even higher energy density and can therefore store even more electricity. The service life of redox flow batteries is also longer than that of lithium-ion batteries. This means that they last longer and are therefore cheaper to purchase.

Supercapacitors are another new technology in electricity storage. They have a very high energy density and can therefore store a lot of electricity. The lifespan of supercapacitors is also very long, which means that they last longer and are therefore cheaper to purchase.

Powerwalls are another new technology in electricity storage. Powerwalls are batteries that are mounted on the wall and therefore save space. Powerwalls have a high energy density and can therefore store a lot of electricity.

The market for renewable energies is growing. Global investment in renewable energy has almost doubled in the last decade. While we are experiencing the biggest boom worldwide, in Germany they are declining, except for photovoltaics. In 2019, around 11 billion euros were invested in Germany. The focus of these investments was in the area of ​​solar energy.
