With chargeBIG you invest in a sustainable charging solution at your company site and for your company fleet. The centralized system approach offers considerable cost benefits not only for the charging hardware, but also for maintenance. Compared to conventional solutions, the sub-distribution is integrated into the chargeBIG system.
We offer individual solutions for both usage and design. Whether for the activation of the charging processes or the design of our energy management systems.
The chargeBIG charging infrastructure offers single-phase charging capacities between 2 – 7 kW (max. 32 A). Intelligently controlled and single-phase outputs are ideal for daytime parking or charging at night, parallel charging of many vehicles and utilization of the existing grid connection. The phase-individual and dynamic load management controls the charging processes, depending on how many other vehicles are charging and how much maximum power is available at the location. Individual charging points can be integrated into the chargeBIG system with three-phase charging power, i.e. 11 or 22kW (max. 32A three-phase) for visitor parking spaces, for example.
The chargeBIG charging infrastructure pays off from a requirement of at least 18 charging points at one location. The solution is also particularly suitable for larger application areas with up to 100 or more charging points.
The charging cabinet, i.e. the central control unit and the sub-distribution board for the charging points, can control up to 36 single-phase charging points or 30 single-phase and two three-phase charging points when fully equipped.
The chargeBIG solution is not only suitable for indoor use, but also for outdoor use. The charging cabinets for outdoor use can be optionally equipped with a sealing package and/or air conditioning.
The chargeBIG charging points have a permanently installed type 2 charging cable.
The integration of three-phase AC charging points into the chargeBIG system is possible for visitor parking lots, for example. However, the large number of charging points is implemented with intelligent, single-phase charging power. The integration of DC charging solutions into the chargeBIG system is possible on request.
The chargeBIG solution offers the choice between static or intelligent and dynamic load management with a “first come – first serve” strategy. The integration of other power generators or loads in the building is easily possible. Grid-optimized load management based on the grid frequency and load management based on sports market prices are currently still under development.
The chargeBIG solution can be connected directly to the building via the low-voltage main distribution board or the house connection. The load management can balance all other consumers and use the electric vehicles as a shelf load, while other consumers such as the kitchen or the test bench are prioritized. The load management system either reacts autonomously within seconds to defined dynamic or static maximum load specifications or it is integrated into the building management system and follows the specifications from the building management system.
If the local load management fails, for example due to the emergency specification in the building management system or a network failure, all charging processes switch to emergency charging, which can be parameterized to 6 or 10A per charging point.
Charging is activated by scanning the QR code or via NFC using the smartphone camera or the chargeBIG app (web application, iOS or Android app).
The charging process is paid for ad-hoc using common mobile payment methods such as credit card or PayPal. Other payment methods can be integrated on request. If users are not billed directly, it is possible to use voucher codes. All charging processes are summarized in a reporting system so that the charging processes with voucher codes can be allocated to cost centers via internal billing. This is particularly relevant for employer or fleet charging.
The prices at chargeBIG charging points are generally charged on the basis of the kWh consumed, but vary depending on the location and provider. The Eco tariff refers to a dynamic charging capacity of between 2.3 – 7.2kW. The Premium tariff guarantees 7.2kW on the infrastructure side. Optionally, a basic charge can also be defined for the charging process at the location.
In March 2021, chargeBIG’s billing solution was certified by the VDE so that billing can now be carried out in compliance with calibration law. With chargeBIG, the progress of the kWh display takes place via the user-owned smartphone and not via a physical meter at the charging point. The entire technology, including encrypted data transmission between the charging hardware and the backend, has been certified for this purpose.
No, chargeBIG offers billing to the kilowatt hour, the time is irrelevant.
No, our charging stations or wall mounts have a fixed charging cable. Firstly for safety reasons, and secondly for the convenience of the customer.
Any B2B company that needs 18 or more charging points can become a chargeBIG customer.
Unfortunately, there is no general answer to the question of purchase and installation costs, as many factors have to be taken into account. Please contact us with your detailed requirements and we will be happy to provide you with a non-binding quote. In order to be able to prepare a binding offer including installation and full-service solution, an on-site inspection is required.
There are a variety of different funding programs for the development of charging infrastructure, some of which have different requirements depending on the federal state or industry. chargeBIG will be happy to support you in choosing the right funding program for you and in preparing the funding application.
The chargeBIG solution relies on a proprietary backend developed in-house. This backend transmits more data than specified in the standard for OCPP, such as information on temperature monitoring, overvoltage protection and signals for the fire alarm system. The calibration law also requires certain functionalities in the backend for a centralized charging solution, which were implemented in the chargeBIG backend. We can operate backend roaming via the OICP standard and thus communicate with third-party hardware (AC and DC).
