Fundable charging stations with Charge Control C
Manufacturers of charging stations can guarantee their customers the eligibility for KfW funding
A new KfW support program for private charging stations came into force on November 24, 2020. With this program, the German federal government supports newly installed charging stations at privately used parking spaces in residential buildings.
Eligible costs are the purchase price of a new charging station as well as the costs for installation and connection, including all installation work. Manufacturers of charging stations have to meet the technical requirements for the subsidy.
With our Charge Control C charging controller, manufacturers can easily meet all the requirements for KfW funding.
Eligible charging stations must meet the following criteria:
Charging capacity of exactly 11 kW or more
Charging modes 3 or 4 according to DIN EN IEC 61851-1
3-phase power supply
Secure digital, bidirectional communication interface and control via common, standardized communication protocols to communicate with other components within the energy system
It must be possible to limit the power of the charging station via the control unit or to postpone it according to appropriate specifications
Secure software update capability for future technical developments and new functions
Ability to respond to specifications and schedules of the power and energy management system for maximum grid connection power values from authorized entities
It must be possible to control the charging station at the request of the network operator
Charge Control C complies with all these requirements. By using Charge Control C in their devices, manufacturers of charging stations can guarantee their customers subsidy eligibility and have their devices included in the list of eligible charging stations published by the KfW.
