Optimise the contracted power
DLM System: How can I avoid having to increase my contracted power?
In large car parks, it is unfeasible to increase the contracted power to guarantee every parking space has the full charging capacity available. To ensure every user can charge their vehicle and avoid increasing your contracted power, and with it your monthly electricity bill, you have to install a DLM (Dynamic Load Management) system.
DLM systems feature software that monitors in real time the status of the installation, displaying the vehicles that are charging, the spaces available, and any fault involving a charger. This system can be used to share the charging power available based on how many vehicles are charging simultaneously.
The DLM collects information on how many vehicles are charging, how much power each charging point requires and automatically configures each one to reduce the total power if the sum of the requested power exceeds the contracted power. The system thus reduces the power of those vehicles whose battery is close to being fully charged, allowing more power to be delivered to those that have just parked, until the maximum contracted power is reached. If the maximum number of connected vehicles is exceeded, the system will put new users on stand-by until a slot becomes available.
