EV Charging Connectors: CCS2, Type2 & GB/T Solutions

The cost to charge phev at home is the most significant and controllable factor in the overall operating cost of a Plug-in Hybrid Electric Vehicle (PHEV). For owners who have access to off-street parking and a dedicated charging setup, home charging is almost invariably the most convenient and economical way to keep their PHEV's battery topped up, maximizing the use of electric power and minimizing reliance on gasoline. Calculating this cost is a straightforward but important exercise. It involves three primary variables: the usable battery capacity of the PHEV, the residential electricity rate, and the efficiency of the charging process. For example, consider a PHEV with a 15 kilowatt-hour (kWh) usable battery pack. If the homeowner's electricity rate is a flat $0.14 per kWh, a simple multiplication suggests a cost of $2.10 for a full charge (15 kWh * $0.14). However, this is not the total electricity drawn from the grid. The vehicle's onboard charger converts AC power from the home outlet to DC power for the battery, and this conversion is not 100% efficient. Typical charging efficiency is between 85% and 90%. Factoring in this loss, the actual electricity drawn from the grid to fully charge that 15 kWh battery would be about 16.7 kWh (15 kWh / 0.9). The actual cost at $0.14/kWh would therefore be approximately $2.34. This cost needs to be compared to the cost of gasoline for the same distance. If the PHEV can travel 40 miles on that full charge, and a comparable hybrid vehicle achieves 40 miles per gallon (mpg), the gasoline cost at $3.40 per gallon would be $3.40. In this scenario, charging at home saves the owner about $1.06 for every 40 miles of electric driving, a significant saving over time. The cost can be further optimized by enrolling in a time-of-use (TOU) electricity plan offered by many utilities, which provides lower rates during off-peak hours, such as overnight, when most PHEV charging occurs. The hardware enabling this home charging—the charging cable and the vehicle's inlet—must be safe and reliable.
