Enhancement of defense equipments and
extreme environmental conditions are creating new demands

Enhancement of defense equipments and extreme environmental conditions are creating new demands for advanced battery technology. Increasing trends toward automatically controlled equipment further emphasize the importance of supplying better batteries. In short, safe and high performing batteries can determine the outcome of critical operations.

Kokam aviation battery
UAV / DRONE / FIGHTER JET

UAV, Drone, and Fighter jet require reliable and proven batteries as the operation environment is unstable and extreme. Kokam’s aviation batteries (Manned Aerial Vehicle & UAV battery) are reliable in safety, space efficient and quiet in power source for UAV and other aviations. UAV and drones are controlled from ground-based stations. Such advanced vehicles require advanced sensory, communication and power components to ensure a safe and reliable flight. Installing high tech components into a relatively small UAV and other aviation is often challenging. However compact features of Lithium Polymer battery allow additional space within the UAV and other aviation, which could be used to accommodate various components. The feature helps any kinds of aerial vehicles disposing Kokam UAV battery to be lighter and fly faster than others.

3. UUV / TORPEDO / SUBMARINE

DEPLOYMENT OF LITHIUM POLYMER BATTERIES POWERS STRATEGIC ADVANTAGE

Advanced technology in Lithium Polymer battery is enabling strategic advantages in marine applications. The battery has high energy density both in weight and volume, coupled with the capacity to rapidly charge and discharge, delivering immense amounts of power over many thousands of cycles with minimum degradation. Compared to the lead acid batteries, the Lithium Polymer battery delivers higher amounts of stored energy and power.

Kokam is taking a leading place in the field of Lithium Polymer battery for maritime applications. Examples of large scale deployment of Kokam Lithium Polymer battery include electric propulsion of surface ships (100% battery powered ferries with displacement of up to 3000 tonnes); hybrid ship propulsion to reduce fuel consumption and boost peak power, thus reducing reliance on gas turbines and propulsion of diesel electric submarines with the strategic advantages of increased sub surface range, higher speed, and reduced surface charge time.

As with all technology deployments, safe operation requires a fully engineered solution. In addition, selecting the most suitable technology for each application is imperative for a successful deployment.

For example, the propelling characteristic of a torpedo is remarkably different compared to that of a submarine. Kokam offers customized cells that are best suitable for specific applications.

Kokam ensures the safety of the cells by selecting the appropriate chemical ingredients and adopting rigorous quality management procedures. That is why Kokam has over 10 years of incident-free deployment of Lithium Polymer cells in marine applications such as the UUVs, submarines, and torpedoes.
