Advantages of Spear’s Aerospace Battery Technology
Spear's Aero lithium-ion batteries are perfectly situated to power up unmanned aerial vehicles and propel them through the skies and even provide the necessary energy to run advanced on-board applications without hindering system efficiency.
Spear's Aero batteries are astoundingly safe, lightweight, and reliable and utilize green technologies for low emissions and increased fuel savings. Although lithium-ion batteries can have a reputation for catching fire, our battery management systems monitor the charge of each cell group, managing the temperature, charge, and discharge rates, depending on what is needed. Our BMS prevents overcharging or discharging, as well.
Spear has decades of experience designing and implementing technology for unique aerospace battery solutions.
Aero Aircraft Battery Systems
Spear’s aerospace energy storage solutions start with electrochemical cells, which form the basic building blocks of rechargeable battery systems by chemically storing electrical energy until it is needed. As a cell agnostic battery pack integrator Spear works with the world’s leading high-quality battery cell suppliers to select the right chemistry, cell format, and capacity for your aerospace application taking into account performance, cost, and quality objectives. The Spear team has the unique vantage point of having both developed novel lithium-ion cell chemistries and successfully transitioned high-volume cell manufacturing from an offshore licensee to the United States. This deep expertise enables us to develop an intimate knowledge of our partner’s battery cells ensuring you have the right building block for your battery system.
Today’s commercially mature lithium-ion rechargeable secondary cells can be grouped into some key electrochemical parings as detailed in the table below. Each of these chemistry options offers advantages, whether in cost, life, stability, energy density, or available capacities and formats. The spider plot illustrates these tradeoffs, with more favorable performance in each category lying farther from the center and less favorable performant marked closest to the center.
Unlike other battery cell manufacturers who attempt to force specific chemistries into less than ideally suited applications in order to keep their factories running at capacity, Spear is unencumbered to offer the optimum solution or provide you an unbiased comparison of your cost, performance, and life options.
Spear’s veteran team of hardware and software engineers has developed battery management electronics for portable electronics, unmanned vehicles, advanced weapons, aircraft, and large-scale stationary storage. Spear’s next-generation SBMS builds upon the lessons learned from both this breadth of experience and working with leading industry technology partners. The modular architecture allows for the same circuit and software blocks to be used for 12V to 1250V applications, as well as for deployments of individual modules versus dozens of parallel strings. The SBMS works with all lithium-ion cell chemistries, giving customers a dependable, common communications interface across different applications thereby compressing development and commissioning times. The state-of-the-art SBMS electronics gather the temperature and voltage measurements of each cell more quickly and precisely than other solutions, providing enhanced safety and more accurate prediction of the battery’s state of charge (SOC) and state of health (SOH)
Spear is an expert in the robust, safe integration of lithium-ion cells into high capacity, high voltage strings. Spear’s SMOD provides modular building blocks for the mechanical integration of prismatic pouch or cylindrical can cells into energy storage systems from 12 to 1250 VDC and from 1s to 1000s of Ah. The SMOD’s proprietary thermal management design maximizes both cell life and operational range. The SMOD is a key contributor to the ESS safety architectures, by assisting in the detection and mitigation of faults. The SMOD offers an industry-leading blend of thermal performance within a lightweight, compact volume.
Today’s energy storage systems are complex and require a mastery of multiple engineering and scientific disciplines, which is why Spear’s technical team is made up of a combination of electrical engineers, software engineers, mechanical engineers, manufacturing engineers, scientists, and program managers. Whether installing a typical deployment of our Trident battery system or a new custom ESS, our applications engineers engage directly with our customers’ technical teams at the beginning of every project to fully define the ESS requirements and power system interfaces. Our SBMS and SMOD building blocks enable us to develop proof of concept units rapidly, cutting your time to market. We work together to design within the safety and de-risk key performance criteria. When it comes time to flip the switch, Spear will be there alongside you with test results and diagnostic tools to make certain everything works according to plan - and Spear will continue to be there, with timely support and friendly service, whenever the need arises.
