Bluecongo: a unique mix of technologies for electric vehicles

<< Back

The whole fleet of Bluecongo electric vehicles runs on energy from the sun. So how does this feat of technology actually work?

Technologie véhicules électriques Bluecongo

By harnessing Bolloré Group’s knowhow in the storage of electricity with existing solar technologies such as photovoltaic panels, Bluecongo can produce and use an uninterrupted 24/7 flow of 100% renewable, environmentally friendly energy. The solar energy is captured, stored and redistributed through technology that is totally independent and self-reliant.
The process is based on a solar energy plant made up of 211 photovoltaic panels deployed over an area of 360 m² that gathers and transforms solar energy. This energy is then sent to a storage unit based on the LMP (Lithium Metal Polymer) technology. This “giant battery” has a capacity of 180 kWh. To meet the needs of the All-Africa Games in Brazzaville, Bluecongo has built four solar plants of this type.

Recharge terminals for the Bluecongo electric vehicles

Once the solar energy has been transformed into electricity and stored in containers filled with LPM batteries, the recharging terminals come into action. More than 80 are installed at the Kintélé site. They have been designed to enable rapid charging for electric vehicles in an urban environment. They are especially well suited to harsh environments characterised by corrosion and other wear issues and to intensive use.

At the heart of the system: the LMP battery

The LMP (Lithium Metal Polymer) battery, developed by Bolloré Group via its Blue Solutions subsidiary, is remarkable for its power, high energy density and operational safety levels. The technology is used in all the Bluecongo electric vehicles and solar plant containers. It offers incomparable autonomy and a working life in excess of 3,000 charge cycles.
It is a dry (“100%” solid) battery, offering plentiful advantages. Insensitive to climatic variations, it prevents risks of pollution in the event of accident and is easy to recycle. This is a clear advantage for the protection of the environment.
Bluecongo thus delivers its expertise and knowhow in Congo by offering clean technologies that address the needs of sustainable economic development.
