Scalability Issues:
The EV-charging infrastructure needs to accomodate exponential market growth and a wide range of charging use-cases, which means the EV service providers must be able to upscale their networks while broadening their offerings and providing a seamless charging experience to drivers.
Provisioning Issues:
Every type of charging location has its own requirements--homes, apartment complexes, commercial and industrial sites, gas stations, retail sites, municipalities, and public charging parking lots. This results in complex IT lifecycle management.
Billing Issues:
EV companies need a flexible backend system that also supports open standards for grid and intra-network connectivity. Legacy APIs must also be supported so that billing solutions can seamlessly integrate for new growth and business models.
Communication and Security Issues:
One issue cited most often by charging network operators was poor communication to utility provider infrastructure, which led to costly delays and workarounds. Also, lossy networks in the field makes it difficult to receive telemetric data and send commands OTA to the devices.
