The global commercial aircraft battery management system market is expected to post a CAGR of over 7% during the period 2018-2022.
A key factor driving global commercial aircraft battery management system market growth of the market is the mandatory regular battery monitoring noted Technavio in its latest report. New-generation commercial aircraft use Li-ion batteries as a major power source located in the forward electrical equipment bay and APU.
These batteries support the refueling operations and enable power braking systems when the aircraft is towed.
They also support the functioning of critical electrical power equipment in the case of a power failure. BMS is used to monitor and balance the charge of individual battery cells that are in series and also provide fault detection of individual cells in parallel within a battery pack of hundreds of cells.
Li-ion batteries are the most popular and advanced battery technology in production and are used for high-energy or high-power systems.
Usually, during usage, the individual cells in a battery never behave identically due to factors, such as the fabrication process and external conditions. In order to endure optimum performance of a battery, the battery cells should be continuously balanced to maintain the variation of SoC within a small range. Without an appropriate balance among the cell voltages, the battery capacity will decrease rapidly, limiting the range of the electric aircraft and shortening the lifetime of the battery cells.
“BMS play a crucial role in improving the performance of the electric aircraft. It protects the battery from damage and extends its lifespan. The purpose of BMS involves measuring of certain parameters like the system voltage, current, and temperature; the cells SoC and SoH. Based on these, it determines the remaining useful life of the battery,” says a senior analyst at Technavio for research on aerospace products.
The Americas led the market in 2017 with a market share of nearly 69% of the market share. The market share occupied by this region is anticipated to decrease by nearly 3% during 2018-2022 said Technavio report.
