Frequently asked questions about our ELECTRIC MACHINES
The electric runtime varies depending on many factors such as individual driving behavior, type of use and environmental conditions. The achievable runtime without intermediate charging varies between approx. 4 hours and 2 hours.
Type of use: (short vs. long distances, working with bucket vs. working with fork, regeneration phases vs. continuous operation, etc...). The type of use has an enormous influence on the actual runtime. Without taking other factors into account, the runtime can therefore vary by 50% depending on the type of use.
Surface condition: (asphalt, unpaved gravel road, predominantly soft surface, very soft surface). The softer the surface, the higher the power requirement. In addition, slippage increases with soft ground. Both factors therefore influence the running time of the e-machines.
Type of terrain: (continuous flat, slight inclines, steep inclines). Driving on slopes increases the power requirement and therefore influences the running time of the machines.
Driving behavior: Proactive driving has a positive effect on the runtime. Rapid acceleration of the machine leads to extremely high energy consumption of the drive system motor. The running time can be positively influenced by avoiding rapid acceleration or by proactive driving behavior.
Outdoor temperature: The outdoor temperature also has an influence on the running time of the machine. Especially in the winter months, we recommend charging and storing the wheel loader or the telehandler at room temperature. For example, in a garage or machine hall. This keeps components such as axles, transmission or the hydraulic system warm - this also influences the running time.
Auxiliary consumers: (heating, opt. oil cooler, radio, lighting). The heater is by far the largest auxiliary consumer, since it is operated directly from the battery and not via the waste heat of the engine, as is usual with combustion engines. Thus, the influence on the running time is relatively high. For this reason, we recommend parking the vehicle in enclosed and heated buildings when outside temperatures are low, if possible. This way, the heater only has to maintain the temperature of the cab instead of heating it up completely. The other auxiliary consumers do not have an enormous influence on the running time, but should also be taken into account for realistic consideration.
Use of the service brake: As soon as the operator takes their foot off the accelerator pedal, the drive system switches to recuperation (energy recovery). This means that the kinetic energy of the machines is converted into electrical energy and is recovered. During the recuperation phase (vehicle coasting), electrical energy is fed back into the battery. Recuperation is not possible when the service brake is applied.
Fast charging on the electric wheel loader is possible by an integrated battery charger with up to 9 kW. Different charging cables and adapters are available.
Fast Charging on the electric telehandler is possible with an integrated battery charger with up to 3 kW or with up to 6 kW charging power. Different charging cables and adapters are available.
Yes. Intermediate charging allows the battery to be recharged at any time, such as during breaks.
At an electricity price of 35 cents per kilowatt hour, a complete battery charge costs approx. €13 with approx. 37.5 kWh.
E-vehicles are significantly more efficient in practice than hydrostats. The longer an e-vehicle is on the road, the better its cost balance
Charging the battery to 80% is possible in about 3 hours. Data depends on machine equipment, application and environmental factors and may vary.
When the last LED of the battery charge level indicator starts to flash, the last stage of the so-called derating mode is activated after a short time. In derating mode, the torque and also the driving speed are reduced - in extreme cases to as little as 3 km/h. If the vehicle is operated near a 3-pin or 5-pin 16A CEE socket, the vehicle can be operated until the speed is reduced to 3 km/h. The drive is not switched off completely. As soon as the speed has been reduced to 3 km/h, the battery must be charged immediately, otherwise the battery will be deeply discharged. Deep discharge must be avoided at all costs.
According to the Battery Ordinance, battery manufacturers are legally obliged to take back your used batteries. In addition, you have the option of taking the batteries to a designated recycling center and paying for their disposal yourself. For more detailed information, please contact your Kramer sales partner. AGM batteries and their contents can be recycled up to 65%. If required, you as a customer will receive a written declaration on the proper recycling of the used battery.
Any government grants will depend on your location. Different state governments have different rules regarding e-mobility. For more information, please contact your Kramer sales partner.
Yes. The warranty period is max. 2,000 operating hours or twelve months from handover by the distributor to the first end customer. Furthermore, the warranty period can be extended up to 3 years or 3,750 hours. For more information, please contact your Kramer sales partner.
The electric wheel loader basically has the following advantages over a diesel machine: Fewer components and fewer maintenance points: Whereas some typical components and combustion engine fluids are omitted (these include engine components such as air, fuel and oil filters, V-belts and spark plugs, but also fluids which have to be replaced at regular intervals), the special elements of an electric wheel loader are included in the maintenance list. This includes, for example, the annual insulation measurement. In addition, the charging equipment and cable connections as well as the condition of the battery are examined as part of the general maintenance. In principle, an electric wheel loader also requires maintenance at regular intervals, but an expensive oil change with filter is a thing of the past.
No, with the Kramer e-machines you can work on site completely emission-free. If you charge your electric vehicle with renewable energy, you can minimize your CO2 footprint even further.
The Kramer electric wheel loader has the same performance as the comparable conventional diesel machine. There is no need to compromise on performance,
tipping load, payload, etc. The electric telehandler is also comparable to the diesel engine in terms of its performance data.
As part of the Wacker Neuson Group, Kramer aims to further extend its leadership in the field of electromobility by implementing our Zero Emission
strategy. Here, we are concentrating on customer benefits, profitability and innovations.
We believe that the compact products segment will continue to grow significantly and that electric machines are the future, especially in the
However, for many machine sizes, applications and markets, the diesel engine will remain the most suitable power source for some years to come.
For this reason, Kramer will introduce more electric machines and at the same time continue to develop the current range of diesel engine machines
based on market demand and regulatory requirements.
Lithium-ion batteries are used (NMC cells). This type of cell
is also used in the Renault Zoe, VW ID3, Audi E-Tron or BMW I8 and BMW I3,
The electric wheel loader has a capacity of 37.5 kWh.
The electric telehandler has an 18 kWh battery as standard and a 28 kWh battery is available as an option.
The lithium-ion batteries are designed for the entire service life of the machine, which is at least 5 years or min. 2000 full charge cycles (whichever comes first). After this time, we guarantee that the usable capacity of your battery will not fall below 80%. The battery can still be used even after that.
The batteries are permanently installed - to prevent vandalism or theft. Therefore, removing the battery only makes sense and is only economical in the event of servicing, with a certain amount of work and time required.
If the vehicle is parked for a longer period of time (more than three months) and is not charged, the battery capacity should not be too low but also not too high. The optimum range for battery capacity during longer periods of disuse is 30 % - 50 % SOC.
