Lithium Ion Battery Charging Unit Objective Electrical and

Lithium Ion Battery Charging Unit Objective Electrical and Mechanical Design Coupling Update a current battery charger to functionally and physically support the latest single cell battery pack for Itron’s handheld meter reading device. Specifications Electrical Design Outline design space using functional requirements Outline electrical schematic using functional specifications Case design and contact integration with printed circuit board The cost of the charger must be similar to the current charger. The charger must accommodate 2 new lithium ion battery packs. The charger must have same shape, color, and material as current charger. The battery charger must accommodate vertical battery installation. The battery charger must charge battery pack in 3 hours or less. Mechanical Design Provide physical space for electrical components Iteration Give feedback on space provided for components Initial printed circuit board configuration inside mechanical design space Mechanical finalization with final printed circuit board configuration Printed circuit layout design with placed parts, routed wiring, and connections Mold fabrication and production of charger case & charger contacts Printed circuit board manufacturing, part insertion, and part connection Coupled Design Battery charger functional prototype The battery charger must contain a light emitting diode (LED) with flashing red indication for battery charging, and a solid green indication for battery charged. The battery charger must dock with the current model, using the same gang connect printed circuit board and wall power supply. Lee Solum, Joe Cote, Rory Olson, James Franklin The battery charger must operate within a temperature range of: 0 C – 40 C. The battery charger must pass FCC class A emissions for 4 chargers.
