Intervention vehicle for electric cars

Automobile association VAB asked the E&A research group of the KAHO Sint-Lieven college to develop an intervention vehicle in cooperation with a number of industrial partners. The intervention vehicle has to be able to recover electric vehicles in a very environmentally friendly, efficient way and had to meet three conditions:

  • The intervention vehicle must run on natural gas (CNG) rather than diesel.
  • The intervention vehicle must have a battery pack on board with sufficient green power for breakdown recovery of four electric cars.
  • Additional power can be drawn from rapeseed oil by a highly efficient hybrid power unit on board the intervention vehicle.

The lithium power pack consists of 16 LiFeYPO4 lithium cells of 3.2V with energy storage of 20.5kWh on 48VDC. The lithium battery pack is charged with 3 powerful Victron Energy Quattro 48/8000 inverters/chargers, which reduce charging time to 4 hours. The Quattros run on the power unit (generator). The Quattros are used as inverters to power the fast chargers for the batteries of stranded electric cars. The system is set up as a 3-phase 3x400V+N network on the AC side.

Ysebaert supplied the energy system, which was designed and installed together with KAHO Sint-Lieven college.

SUV with high-speed cameras and lithium power pack

Company WIM ROBBERECHTS & Co was looking for a compact but powerful autonomous energy system to be built into a hybrid SUV. The requirement was the ability to provide power to 2 high-speed cameras and other video and broadcasting equipment for 5 to 6 hours. During our first meeting it quickly became clear that an energy system with lead-acid batteries would be too large and heavy for the car. The lead-acid batteries weighed 560kg and left no room for the installation of the other equipment. The choice of an Ysebaert lithium-ion battery pack was obvious, as a 24Vdc/700Ah lithium power pack (17kW) only weighs 189kg. A Victron Energy Quattro 24V/5000VA inverter/charger ensures sufficient power to provide 230V to all equipment. The Quattro recharges the lithium batteries very quickly. Two cars were given a 24V/400Ah (11kW) lithium power pack and the third is using a 24V/700Ah (17kW) pack.

Ysebaert was responsible for the system’s engineering, assembly and installation in the vehicles.

Nautitech Catamaran equipped with a hybrid energy system

A charter company sought Ysebaert’s advice on a state-of-the-art hybrid energy system for a 54-foot catamaran. We soon found that a lithium-ion battery pack system was the ideal solution due to its quick charge time and low weight compared with conventional batteries.

At the heart of this hybrid energy system is a lithium power pack including a 10kWh BMS on 12VDC, a Victron Energy Quattro 12/5000 inverter/charger and a silent Fischer Panda generator 10.000i PMS.  As the catamaran is mainly chartered in a sunny climate, we chose to install an extra energy source with 1kW Solbian flexible solar panels and a high-efficiency Victron Energy MPPT 150/70 charge controller.

Ysebaert was responsible for the engineering, delivery and the on-site installation of the system in France.

Multifunctional truck with solar energy

Our customer Fisheye needed to have power in the middle of the jungle. Chocolate manufacturer Barry Callebaut required the development of a Cocoa Horizons Truck to be used in Ivory Coast. This African country is the biggest producer of cocoa in the world. The truck will be used to teach children how to read and write and to tell them all about child labour, agriculture and health. With this truck, Callebaut wants to encourage the farmers in the region to continue to grow cocoa.

The most obvious power option was a generator, but this would harm the project’s green image. Solar panels were the solution, but conventional solar panels are not suitable for installation on a container, as they are too fragile. Solbian solar panels, however, are very suitable for applications such as this one. The truck is now equipped with 1.2kW in flexible overflow solar panels that charge the 24Vdc 800AH (19kW) gel batteries through a Victron Energy MPPT 150/70 high-efficiency charge controller. A Victron Energy Multi 24/2000VA inverter/charger provides 230VAC power supply. The BMV600 battery gives users a visual/acoustic representation of the energy yield of the solar panels, the consumption and the remaining battery capacity.

Ysebaert was responsible for the entire energy system from development to installation.

Industrial self-consumption system

An industrial company in the Netherlands had the idea to generate solar energy during the day for charging the batteries of its forklift trucks at night. Together with GNB (Exide) we developed a self-consumption energy system.

The three-phase energy system consists of 3 strings of solar panels, 3 Victron Energy 2800W grid inverters, 3 Victron Energy Quattro 48V8000VA inverters/chargers and an OPzV 48V 1500Ah battery pack (72kW buffering).   

The green electricity generated during the day is used to charge the 48V-1500Ah battery pack through the Quattros. The forklift trucks are charged at night through the inverter section of the Quattro and the GNB special chargers. The system is configured to operate completely independently.

The new Victron Energy Color Control data display shows customers live data on a local Smart TV or at any location via a web interface.

Ysebaert and GNB were responsible for the development, assembly and on-site installation of the self-consumption energy system.
