Charging
Basic concepts of simultaneous and sequential charging
- simultaneous
charging
-
- Complete 70~80% of the vehicle battery charge at port A
- After 70~80% charging, reduce the charger output at the request of the vehicle
- Start charging at port B with idle power due to power reduction
-
Maximize operating rate and increase operating profit by reducing the time required for full charging
-
Improve management efficiency and easy to install chargers through power distribution system
-
Cost reduction by minimizing electricity receiving costs, installation costs, and standby power
- sequential
charging
-
- Charging of Port A is completed
- Charging of Port B starts automatically (sequential charging)
- Use of late night hours when electricity costs are the lowest
-
Synergistic benefits for transportation and courier companies where late-night charging is essential
-
Reduced labor costs for vehicle charging and moving fully charged vehicles
Example of peak management of charging stations in intelligent power distribution, compared to integrated charging
- General charging [low operating rate compared to facility capacity]
-
- Multiple chargers in a site is doomed to bear the tantamount increase of contract power and thus, expensive but inefficient bills
- Power use is patternized to peak at certain times of a day while close to dormant at the rest
- Intelligent charging [Optimizing the operational efficiency of facility capacity]
-
- Reduced the amount of per site demand power (as low as 50%)
- Stabilize power supply and demand through peak power management
- Provide preliminary grid investigation and operation plan suitable for the particular site
