Recently, ABB Group, headquartered in Switzerland, has attracted industry attention for a technology called “Flash Charging”. According to the information obtained from ABB (China) Enterprise Communication Department, “This technology was designed to be promoted globally

The system has been operating on the route between Geneva Airport and Palexpo Exhibition Center since May 26th and will continue until March 14th, 2014. The head of the company stated that this technology is suitable for ordinary cities, large cities, and mega cities seeking sustainable public transportation solutions. Used for high-frequency bus routes to alleviate traffic congestion in urban areas

According to ABB, this technology is equipped with a water-cooled lithium titanate oxide LTO battery pack with a service life of 10 years. There is a rooftop charging system at the station that can charge for 15 seconds at a power of 400 kilowatts. These charging systems are connected to the power grid and equipped with intermediate storage devices (supercapacitors) to reduce the impact of short-term high power on the grid. The fast charging point can charge buses up to 1.65 kWh. In addition, at the bus terminal, there is a 200 kW charger that can fully charge the battery in 3-4 minutes.

At present, pure electric buses using this technology can carry 135 people. When the vehicle stops at the station, it is located by infrared, and the charging point on the roof is connected to the moving arm controlled by laser after positioning. After completing a 15 second recharge, the vehicle continues to move forward without affecting the normal operation of the bus. Its concept is similar to that of a tram, but it does not require the installation of a complex network.

In addition to ABB, similar concepts of fast charging during driving are also being promoted by many companies in China. During an interview with reporters, Wang Binggang, the leader of the supervision and consulting expert group for the National 863 Program’s major projects on energy conservation and new energy vehicles, referred to this mode as “online charging” The online charging mode can effectively solve the contradiction between battery quantity and range Wang Binggang stated. It is reported that currently, bus companies such as Hunan CSR Times Electric Vehicle, Youth Bus, and Hengtong Electric Vehicle are developing and promoting similar technologies.

As a Fortune 500 company, ABB’s business scope includes power and automation technology. In the field of electric vehicles in China, ABB is a supplier of DC drives, motors, programmable controller products, electric vehicle charging infrastructure, and energy storage products. In the field of charging infrastructure, ABB has not had a good opportunity, perhaps the latest “flash charging technology” can find some market space for ABB.
