Customer
A reputed Tier-I Automotive Supplier, based out of Europe, our customer partners with Global Automotive OEMs’
for Seating, Interiors and Emission control solutions
Business Challenge:
Our client has conceptualized a Solar based battery charging item for Electric Vehicles. This item is a PoC to address end-
client torment purpose of each time scanning for a charging point/station for their Electric Vehicles.
With intends to at first dispatch this Photovoltaic (PV) battery charger for European market, our client was on a post for an
implanted item building administrations organization. They needed to band together with an administrations organization
that has car space learning and implanted programming and equipment advancement skill.

Embitel Impact:
DC-to-DC convertors are by and large cumbersome gadgets. Be that as it may, our installed equipment improvement group
could accomplish a testing focus of streamlining the frame factor to under 10 mm (counting boxing)
Such advanced car equipment configuration guaranteed cost reserve funds for our client
This is additionally an one of its kind Solar Based Automotive item with double power yields to serve the different
utilizations of electric vehicles:
• 12 V yield for Head lights, HVAC, Indicators, Music Systems and comparative applications
• 48 V yield for stopping mechanisms, control directing, turbochargers, outflow control, subterranean insect bolt slowing
mechanisms and comparable applications

Embitel Solution:
After beginning counseling workshops, the client created confide in the capacities of our Automotive Product Development
groups. Our involvement in Solar energy based products and over 11 years of space mastery in car guaranteed this was an
esteem include association for our client.
• We joined forces with the client for programming and equipment advancement of PV DC-to-Dc convertor to charge both
48 V and 12 V batteries in an electric vehicle
• Equipment advancement utilizing V-Shaped HDLC demonstrate:
1. HRS, Schematic Preparation and Analysis, Layout, E-BOM acquisition, Fabrication, get together, block bring and
Functional Testing
2. This car review configuration was tried and checked utilizing EM Analysis , Thermal Analysis, Signal Integrity and Power
Integrity tests
3. Equipment configuration additionally included Reverse Polarity Protection and Isolation

Embitel Solution:
• Outline and advancement of Design two-arrange MOSFET based H-Bridge converter. This two phase dc-dc change
accomplished higher effectiveness and support up to 200 W control exchange.
• Layered programming engineering created utilizing V-Shaped SDLC display:
1. MPPT (Max Power Point Transfer) based programming code was intended to accomplish 97-98% proficiency (changing
over 16 V sun based energy to yield of 12 V or 48 V)
2. Outlined and built up a product with knowledge to abstain from depleting of batteries. This is guaranteed by removing
the supply when upper or lower control edges were crossed
3. LIN based correspondence interface to choose yield of either 12 V or 48 V in view of the application
