A better aircraft battery design

Researchers have taken steps towards a new generation of aircraft batteries by designing and testing new lithium-ion (Li-ion) battery systems.

Current nickel-cadmium (NiCad) aircraft batteries have not been improved upon in many years. New developments in Li-ion battery technology offers better power-weight ratios and performance enhancements over NiCad battery technology. The EU-funded BASIC (Battery modular system integrated with conversion) initiative worked to develop a new aircraft power source by optimising weight-volume ratio of the power conversion system and using Li-ion batteries for power storage. Researchers began by reviewing the available battery designs (referred to as architectures), considering factors such as safety, mission profile and weight impact. From this review, they identified four potential designs. BASIC then designed various components to test these architectures. They built a two-part battery system made up of a cells module and a battery cover that incorporates all the electronics needed. This design ensures that the battery is safe by separating parts that could cause short circuits and reducing the chance of damage affecting the battery function. The modular battery design should also reduce assembly time and make repairs easier. BASIC research and deliverables are an important step towards a more efficient and sustainable aeronautics industry.
