Level 2 DC Charger Solution for Home Use:

This project is based on the demand for home charging in the US market. Typically, home power grids only have single-phase Level 1and two-phase Level 2 AC charging, but with the increasing popularity of electric vehicles, AC charging stations are no longerable to meet the fast charging needs of most users. However, DC charging stations with 20kW or more often require three-phaseinput. To address this issue, Qingdao Penoda has developed this solution.

Level 2 DC Charger Solution for Home Use:In this solution, we use 3*7kW DC modules in parallel for a 21kW DC charging station, and 4* 7kW DC modules in parallel for a 28kWDC charging station.

Dynamic Load Balancing SolutionWe will connect a smart meter to the customer's home power grid and charging station. The meter will monitor and transmit data tothe charging station in real-time. When other appliances in the home consume more power, the charging station will receive asignal and automatically reduce its power to maintain the overall load balance of the home. This allows the charging station tocharge quickly during periods of low power usage, while avoiding overloading other appliances during peak usage periods. Thedynamic load balancing (DLB) can also be controlled through the app. Customers only need to input the total available current ofthe power grid, and the charging station will automatically adjust its output power to balance the load based on the data from themeter or CT clamp.

1. APP Control* Setting Current: you can set the current when the power grid is overload.* Controlling Stop & Start: Control the Stop & Start by your phone, you can control it in anywhere.* Making an Appointment of Charging: If you want the electric vehicle to be charged in night, it is a good choice that you makean appointment of the charging by APP, it is very convenient.* Record: you can check the charging record by APP in any time.* The best Choice for home market

2. Load balance management： * Restricting the total charging load protects the local grid * Sharing the charging load cuts costs for the required electricity connection * Choose an open type CT (current transformer) as the current sensor, It is no physical wiring between the devices, which has the advantage of open and close installation, convenient and fast wiring, no extra infrastructure or installation costs.

CAUTION: 1. Don't submerge the ev charging box in water; 2. Don't step on, fold or knot the cable; 3. Don't drop the EV charging box or place a heavy object on it; 4. Don't place the charging cable near high temperature object when charging； 5. Don't operate the EVSE in temperatures beyond its operating range of -25°C to 55°C； 6. Power-supply side input cable should be at least 3*2.5mm, with a standard 16A socket； It is suggested that the power distribution is done by the professionals； 7. Don't put fingers into the charging connector when the power plug is still connecting to the power; 8. Don't use this ev charging box when the cable is damaged; 9. The ev charging box is only for ev charging using;
