Software Development for EV On-Board Charger
The transition to EVs is being primarily driven by rising technical improvement in vehicle electrification, spanning from battery to power electronics, charging to vehicle engineering, as the world prepares for the E-Mobility revolution and the adoption of sustainable forms of transportation.
The "On-Board Charger" (OBC) technology that is included with the electric car enables plug-in hybrid (PHEV) and battery electric vehicles (BEV) to charge their vehicles using AC power or anywhere there is an AC power source, whether at home or in public spaces.
OBC is effectively in charge of transforming grid-supplied AC power to the DC voltage that is needed to charge the vehicle's battery pack. Besides. It also looks after charging the battery pack in addition to providing charge monitoring and safety.
Embitel, with an experience in the automotive industry spanning over 15 years, helps in custom design and development of On-Board Charger solutions for EVs.
