Everything you need to know

Blue Pac is installed on larger lorries and powers the superstructure, which is normally driven by the lorry's idling engine.

For example:

• Crane operation
• Waste compaction
• Tank filling and emptying
• Rotation of cement mixer
• Depending on the desired operating time and performance, one or more battery modules are used, corresponding to 23.5kWh, 47kWh, 70kWh, etc.

We usually talk about effective driving time, which is the time when work is performed in the form of movement. The length of the effective driving time is determined by how heavy the work task is, which is measured in hydraulic pressure and flow over time. A crane operator's working day usually involves around three to four hours of effective driving time, depending on the task, which can be managed with two battery modules. For a refuse collection vehicle to be able to compact waste for a whole day, one battery module is usually sufficient. Consult your bodybuilder about your needs.

Approximately 15 to 20 litres per working day for a refuse collection vehicle.
Approximately 20 to 30 litres per working day for a crane truck.

The motor module contains chargers that start automatically when a cable is connected between the wall socket and the motor module. The charging sockets are standard connections of the type: CEE 3-phase. 400VAC. 16A.

You should expect a charging time of 6 to 8 hours to charge a battery pack from 0% to 100%. However, it is rare for the battery to be completely depleted, which shortens the charging time.

The motor module includes 1 to 2 charging units. If fast charging is desired, an external charging cabinet is included, which is installed at the truck depot or, alternatively, on the truck chassis if space permits. The power of the fast charger is determined in consultation with the customer. Maximum fast charging from 0 to 100% takes 1 hour.

We do not recommend charging via generator operation. With a generator, the energy must pass through several components, each with their own energy losses. This in turn increases total fuel consumption more than is saved from PTO operation. However, if it is possible to utilise the braking energy from the truck with the approval of the truck manufacturer, this is something we support.

It is also worth noting that normal charging can use electricity from clean sources such as solar, wind and water instead of the truck's fuel.

Yes, it is possible to charge the system during use with the charging cable connected.
The charging current is usually sufficient to keep the battery fully charged while driving, thanks to natural breaks in the driving cycle. The truck's charger for the starter battery is also connected to the 3-phase glove for Blue Pac, so it charges at the same time.

Our system is a completely separate system that can be used independently of the conventional engine. If necessary, the superstructure can therefore run on its diesel/gas-powered PTO without affecting Blue Pac.

The system is designed to withstand all types of climates and weather conditions in temperatures ranging from -20°C to +45°C.

The robust modules are designed to withstand the harsh Nordic climate with rain, snow and salt, as well as hot summer days. The modules are sealed and protect the electronics from water damage, and thanks to automatic heating in winter, Blue Pac can be used all year round with minimal maintenance from the operator.

The electric motor is 32 kW with a capacity of up to 45 kW. The maximum working torque in terms of hydraulic pressure and flow is 340 bar and 80 L/min for short periods.

• A motor module with standardised mountings
• One or more battery modules with advanced battery monitoring and associated fasteners
• Remote monitoring of system health and battery status.
• Power cables
• Communication cables
• Display with bracket
• Installation instructions and a Blue Pac manual

We use lithium iron phosphate batteries, commonly referred to as LiFePO4. The advantage of LiFePO4 is that it is a proven and safe chemistry. The battery is monitored by an advanced safety system to optimise its service life and protect the system from misuse. The system has an expected lifespan of 5 to 10 years, depending on the degree of use.

For superstructures that require rapid movements with considerable variation, a variable hydraulic pump is recommended. In cases where the superstructure operates at a constant speed, a fixed hydraulic pump is recommended.

The system is modular with various options to choose from. The motor box contains control electronics and a motor with two standard motor size options.
The battery box is 23.5kWh 96V 230Ah. You can also choose to use multiple battery boxes, which provides an additional 23.5kWh per battery, i.e. 47kWh, 70kWh, etc.

We have designed the boxes to fit all types of chassis frames, and the external dimensions cannot be changed.

The entire system is designed to be easy to use and install.
All cabling comes with ready-made connectors, making it a plug-and-play system.
The modules are equipped with brackets that fit perfectly with the truck frame for quick installation, and the work should take no more than a day.

We have prioritised serviceability when designing the system. The system is essentially maintenance-free, but we still recommend having a certified service technician inspect the system once a year. The service work itself rarely takes longer than 30 minutes.

We sell Blue Pac to bodybuilders, lorry suppliers and bodywork suppliers.
