Fraunhofer scientists are developing a high-performance battery for hybrid cars that is more resilient, reliable and less harmful to the environment.
Researchers are developing an energy-storage module based on lithium-polymer accumulator technology that is suitable for use in vehicles as part of a project dubbed ‘Electromobility Fleet Test’.
The pilot project was launched by Volkswagen and
‘This module has to be able to withstand the harsh environmental conditions it will encounter in a hybrid vehicle, and above all it must guarantee high operational reliability and a long service life,’ said Dr Gerold Neumann, who coordinates Fraunhofer activities.
The researchers intend to use new electrode materials that are kinder to the environment and to develop a battery-management system that makes the energy-storage device more durable and reliable.
To keep the size of the unit small without compromising on power, the team will integrate mechanical and electrical components in a single module, incorporating systems for temperature control, performance data registration and high-voltage safety.
The development and configuration of the new energy-storage module is expected to be finished by mid-2010. Volkswagen will then carry out field trials to test its suitability for everyday use in the vehicles.
