This type of charger must be hardwired rather than plug-in. It can provide high power output at 240V, enabling most vehicles to be fully charged from depleted to full in approximately 4 to 6 hours.However, the actual rate still depends on the vehicle's on-board charger capacity, not all models can be completely used 80A of power output, therefore before installation should confirm compatibility, to ensure that both can implement efficient charging, but also ensure the safe and stable operation of system.
In most areas, installing an 80A EV charger requires an electrical permit application. Owners must submit relevant documents and obtain approval before construction. The licensing process usually takes one to two weeks. The application content includes electrical load calculation, circuit diagram, equipment specifications and a site plan showing the location of the charger. Under normal circumstances, licensed electricians will apply for a license as part of their services. They are familiar with local regulations and inspection procedures and can ensure that the installation is compliant.In some areas, the installation process also requires a separate inspection of the thick wiring and final wiring, and the electrical inspector will finally approve and close the permit after confirming that the installation meets the specifications.
Circuit
When configuring the circuit for an 80A EV charger, a 100A circuit breaker needs to be installed in accordance with the 125% rule to ensure safe operation under continuous high load. Circuits typically use 3 AWG copper wire or 1 AWG aluminum wire and are required to be equipped with four conductors, including two live wires, one neutral wire and one ground wire. At the same time, the electrical panel must have sufficient capacity to withstand an additional 80-ampere load. Many households may need to upgrade the main panel or add sub-panels to meet the demand. It should be particularly noted that this circuit must be dedicated to the EV charger and cannot be shared with other devices to ensure the safety and stability of the system.
Installation
When installing an 80A EV charger, it is usually recommended to fix it at a position about 48 inches above the ground to facilitate operation and cable management, and ensure that the charger is within 2 to 4 feet of the vehicle's charging port to allow the cable to reach easily. Wall-mounted installation is the most common method, which saves space and can provides stable support. The mounting surface must therefore be able to withstand the weight of the charger itself and the tension of the cable. If it is installed in an indoor garage, a better protective effect can be achieved. In outdoor environments, it is necessary to use enclosures with NEMA grade and add rain and wind protection measures to ensure safe and reliable operation under various weather conditions.
Cost
The overall cost of installing an 80A EV charger is typically between $2,500 and $4,500, which includes equipment, materials and labor costs. The price of the charger itself is approximately between $600 and $1,200, depending on the specific function. However, the cost of installation labor and electrical materials will increase additionally. If the capacity of the household electrical panel is insufficient, an upgrade of $1,500 to $3,000 will have to be paid. This part is often the main variable of the overall cost. In addition, most regions also require an electrical license application, with the cost usually ranging from $100 to $500. In some areas, the inspection fee is included, while in others, a separate charge is required.
Difference Between 80A EV Charger and other EV Chargers
An 80A EV charger can provide 19.2kW of power at 240V, which is much faster than the common 16A, 32A, 40A and 50A chargers. For instance, a 16A charger outputs 3.8kW. It takes about 16 hours to fully charge an EV with a 60kW battery from zero, while an 80A charger only requires approximately 3 hours, which is about five times faster. The 32A charger can provide 7.7kW of power, increasing the range by 25 to 30 miles per hour. The 40A charger outputs 9.6kW, and the common charging time is between 6 and 8 hours.
