At Bauma 2025, Sennebogen will be presenting two recycling material handlers from the new G-series with battery drive for the first time: the 824 Electro Battery and the 826 Electro Battery.
In addition to all the advantages offered by the 6th machine generation from Sennebogen, these two battery-powered machines are characterised by the fact that the battery capacity can be flexibly configured.
The 824 G Electro Battery and 826 G Electro Battery also feature high load capacities and long reaches of 12 and 13 metres respectively.
The intelligent, latest-generation Sencon control system installed in the machine enables intuitive and customised operation for the driver or the application, as well as cost-saving remote maintenance options.
Equipped with a battery-powered electric drive, the machines operate completely free of CO2 emissions and each save over 60 tons of CO2 per year. Not only are people and the environment noticeably relieved, but operating costs are also reduced, as the service requirements for the Electro Battery models are very low and no fossil fuels such as diesel or engine oils need to be added.
Thanks to the modular battery concept, the machines can also be flexibly adapted to different application requirements in terms of performance.
Both machines are equipped with a 90kW electric motor. Depending on requirements, one, two, three or four powerful lithium-ion battery packs can be configured and retrofitted. This gives customers maximum flexibility and future-proofing, as they can initially choose the most economical solution for them and increase the battery capacity later if required.
Each battery pack delivers approximately 98kWh, which means that when equipped with four battery packs, each can be used for six to seven hours without recharging. The machines are charged quickly and efficiently via two to three onboard chargers on the undercarriage, each with 22kW charging power, so that either 44 or 66kW total charging power per hour is possible.
Battery-powered material handlers from Sennebogen are characterised above all by the fact that they are designed to be particularly application-oriented and practical. This includes the Dual Power Management System which allows the machine to work autonomously in battery mode as well as connected to the mains.
In battery mode, the machine is supplied with energy exclusively from the battery pack and is highly mobile. If it is connected to the mains via the charging point on the undercarriage for charging, work can continue in stationary mode, as the uppercarriage can be swiveled through 360°. Excess power fed in during the charging process simultaneously recharges the batteries.
Another advantage is that the existing infrastructure of the recycling company can be used, as the machine is charged via a commercially available, standardised 63 A or 125 A CEE plug. There is no need for additional investment in charging stations.
The certified high-voltage battery systems of the two battery machines impress with a long service life of over 4,000 full charge cycles which is achieved by the ideal temperature control of the battery cells in the system.
Thanks to the integrated battery storage, load peaks are also smoothed out (peak shaving), which reduces the grid connection power and saves electricity costs. The fact that no manual intervention in the system is necessary is particularly safe for the operator.
Dual Power Management automatically detects the energy source – battery or mains power – and switches to the appropriate operating mode. As part of regular diagnostics, the machine also independently detects faults and interventions in the high-voltage system and switches off in a controlled manner if necessary.
As an example of the two new battery-powered excavators in the G-series, the 824 G Electro Battery will be one of a total of eight machine innovations on display at the Sennebogen stand at Bauma in the outdoor area FM.712.
