Each E-PAC battery pack has an internal circuit board. This measures the voltage and temperature of the pack and should the pack exceed set current output or a temperature in excess of 80C the pack will shut down.
Battery Type - Lithium Polymer
Lithium Polymer (LiPO) currently offers the most commercially affordable, high density, power source available today.
With a power density of 170 (this is 170W per Kilo)...
An internal processor will monitor the charge and output history of the pack to ensure that no abuse has taken place. The pack will also have an internal fuse system so that is case of damage or severe discharge the fuse will blow. This fuse will only be service replaceable.
The E-PAC balancing charger monitors all 54 cells in 3 battery packs all at the same time. This charger was specially designed at Yuneec and it is the only charger of its type in the world at present, capable of handing this number and capacity of cells. During charging it monitors all the cells holding back high charged cells whilst bringing up any lower cells. In the balancing charge cycle each cell is charged within 0.03Mv of each other. No other commercially available charger can do this and it represents a huge breakthrough for battery powered systems.
Following an increase in specification E-PAC now has two charging systems. One is a full balancing charger which operates as described in the charger section above. A full charge with the balancing charger takes approximately 3 hours.
The other is a standard charger. This charger can be used for quick charging and takes approximately 1.5 hours.
YuneecÃ¢â‚¬â„¢s LiPo battery packs require balance charging approximately every 5~10 charges chargeÃ¢â‚¬â„¢s and so the quick charger is used for normal charging in-between balance charges. Both chargers are required.
The E-PAC controller and motor are fitted with sensors, these control the motor and regulate the operation but also give feedback and act as alarms. In case of high motor temperature the control handle vibrates allowing the pilot to view the data screen and adjuster the power setting to reduce temperature. If this is not done then the software automatically adjusts the power output to reduce the motor temperature.
