BYD is the world's leading manufacturer of batteries, primarily for mobile phones. A BYD subsidiary is also among China's largest automobile manufacturers. An assembly plant for the BYD ebus battery-powered bus was opened in California in 2014. In 2010, the company was named the world's most powerful technology company 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, it only produced rechargeable batteries, which competed with the then market-dominating imported products from companies like Sony and Sanyo.

Industrial robots were first used in battery production in 2011. A very detailed and precise workflow description allowed the production steps to be streamlined so significantly that even young people with little or no vocational qualifications could be employed. This enabled semi-automated battery production of products of comparable quality to those manufactured by industrial robots. However, due to lower wages, considerably below those in Japan, these batteries could be offered at a much lower price. BYD is now also using industrial robots on a large scale.

The Chinese government justified its low-wage policy by arguing that it could create permanent jobs for millions of young people. These people were often unskilled and migrated from rural areas to the cities as China became more urbanized. The government also saw this as a way to secure exports sustainably. From a Western perspective, however, this policy was criticized primarily for the tiring, monotonous tasks, the high workload, and the lack of further training opportunities for the workers.

Low manufacturing costs and high import tariffs on foreign goods in China have contributed to BYD becoming the world's largest manufacturer of rechargeable batteries since 2000. Furthermore, the company holds the largest market share in nickel-cadmium batteries, as well as batteries, chargers, and keypads for mobile phones, and is a key supplier to major manufacturers such as Nokia, Motorola, Samsung, Sony Ericsson, Kyocera, and Huawei.

In 2003, the company acquired the struggling Xian Qinhuan Automobile, thus entering the automotive business; the production division and vehicles have since operated under the name BYD Auto Co. Ltd. The company opted against the faster route of using licensed designs from global corporations and instead focused on developing its own vehicles. By 2010, over 500,000 vehicles had already been produced. Today, BYD Auto is one of China's largest automobile manufacturers.

Starting in 2010, the company continued 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 energy storage systems, which are also marketed in Germany. In January 2012, BYD commissioned what it claims to be the world's largest battery storage power plant with a capacity of 36 megawatt-hours.

Summary:

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

In 2022, a news report claimed that BYD had overtaken Tesla in the world's most sold electric vehicles. This claim was based on BYD sales figures that included more than 300,000 plug-in hybrid vehicles sold in the first six months of 2022. Plug-in hybrids with internal combustion engines are not fully electric vehicles.

Early growth

BYD grew rapidly, capturing more than half of the global mobile phone battery market within a decade and becoming the largest Chinese manufacturer (and one of the four largest worldwide) of all types of rechargeable batteries. BYD topped the 2010 Bloomberg Businessweek Tech 100 list, a ranking of large, fast-growing technology companies. Replacing machine labor with cheap, local workers reduced costs, and the company began expanding beyond batteries, adding automotive and mobile phone components.

Motor vehicles

BYD Automobile Co., Ltd. was founded one year after the acquisition of Tsinchuan Automobile Co., Ltd. in 2002. As one of many Chinese automakers, it was the sixth largest company in terms of sales volume in 2010. On April 3, 2022, BYD announced its intention to discontinue production of internal combustion engine vehicles and focus exclusively on electric vehicles.

Rail transport – Skyrail Monorail

In 2016, BYD unveiled a working monorail prototype, marketed as “Skyrail,” and announced its entry into the global rail market. The first public Skyrail line opened in 2018 as a 9.7 km loop at the Yinchuan Flower Show. Since then, BYD has begun construction on several systems around the world, including the Guang'an Metro and the Guilin Metro in China, Line 17 in São Paulo, and SkyRail Bahia, both in Brazil. BYD is also part of a consortium that has been awarded a pre-development contract to build a monorail from the San Fernando Valley to LAX via Sepulveda Pass in Los Angeles.

Rubber-tired tram

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

Components for mobile phones

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

The new generation of energy storage systems 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 electricity.

New developments in energy storage include lithium-ion batteries, which are now used in many homes and businesses. These batteries are much smaller and lighter than conventional lead-acid 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 manufacture than lead-acid batteries. Prices for lithium-ion batteries have fallen sharply in recent years as the technology continues to improve. Experts expect prices to fall further, making lithium-ion batteries increasingly attractive to consumers and businesses.

The improved technology of lithium-ion batteries has also led to increased demand for these batteries. In recent years, more and more electric vehicles powered by lithium-ion batteries have been sold. An increasing number of companies are also relying on lithium-ion batteries to meet their electricity needs. This is particularly true when they lack access to a regular power grid or when their power supply is unreliable.

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

Redox flow batteries are a further development of lithium-ion batteries. They have an even higher energy density and can therefore store even more electricity. Redox flow batteries also have a longer lifespan than lithium-ion batteries. This means they last longer and are therefore cheaper to purchase.

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

Powerwalls are another new technology in energy storage. Powerwalls are wall-mounted batteries, saving space. They have a high energy density and can therefore store a large amount of electricity.

The renewable energy market is growing. Global investments in renewable energy have almost doubled in the last ten years. While we are experiencing the biggest boom worldwide, these investments are declining in Germany, except for photovoltaics. In 2019, around 11 billion euros were invested in Germany. The focus of these investments was on solar energy.
