EV stands for electric vehicle. EVs have an electric motor in place of an internal combustion engine and are powered by batteries rather than a gasoline tank. Zero-emission vehicles (ZEVs) are vehicles which do not emit exhaust or other pollutant gases due to the power source. All electric vehicles are also classified as zero-emission vehicles, except for the case of plug-in hybrid electric vehicles (PHEVs) that are powered by both a battery and another fuel such as gasoline or diesel.
Wireless charging is an extremely user-friendly and convenient technology that enables the transmission of power through an air gap to a receiving device without any interconnecting cords. You may have seen this technology in action for small-scale charging applications such as cell phones or electric toothbrushes, but one of the major advantages of plugless charging is that it can be efficiently scaled up to much higher power levels for applications such as EV charging.
The two main types of wireless charging technologies are radiative and inductive. Inductive charging is much more practical over close-ranges, since it can safely transmit energy at a much higher level than radiative power transfer.
Typical EV charging solutions provide an efficiency of 60-70%. Our interoperable charger demonstrates a 92% power transfer efficiency in alpha testing, with a goal of 95% efficiency after beta testing and further optimization. Power consumption is reduced by up to 30% compared to other EV charging solutions in the market. This translates to a savings of more than 400 W-hrs per charge in larger e-bikes - quite significant over the lifetime of the vehicle.
Wireless charging is very safe. High power transfer efficiencies mean that very little heat is produced - nearly all the energy goes straight to the EV's battery. In addition, wireless charging can be safer than wired charging since no plugs or cables are exposed, nullifying the risk of sparking or electric shocks in case of a malfunction. Additionally, wireless charging standards ensure that products on the market meet rigorous safety certifications.
OCPP (Open Charge Point Protocol) is the open-source communication standard designed for communication between EV charge points and a central management system. Simply put, it is the language that charging stations and the charging station networks use to send messages back and forth. This interoperable protocol is similar to those used for cell phones and cell phone networks. Just like phones from different vendors can all be used with the same cell towers, an EV from one company can be charged by a station from a different company if both are OCPP compliant.
Yes! In addition to individual charging units, we offer standard and customised charge station fleets to meet the needs of many different charging applications. Reach out to our team to learn more about options for your use case.
