be wrong. It is old-fashioned
lead-acid – and for very good reasons.
“It is a design choice that
we that we made. One of the capabilities of lead acid is that you can reach a very high discharge current from a rather small capacity. We are really a provider of peak power, not necessarily a provider of big energy loads. So for us it is important that we can deliver the high power spikes and that we can do that from a very compact battery pack. If you wanted to have the same peak output power from Li-ion you would need a battery pack that was double the size. “ Of course lithium ion battery
has more energy available, but it cannot release it so quickly. “Lead acid is less expensive. And it is a proven known technology that is very safe. If on your construction site you had a lithium ion battery bank and you bumped into it with a forklift you could have thermal runaway of your battery pack and a fire that would be very hard indeed to extinguish.”

Solutions, a 'provider of peak power'
There is even more: “With lead-
acid we do not need complicated battery management systems to keep the battery in good condition. We do not need active cooling – the system does not need it. We just have a forced airflow. And transporting and handling lithium ion has more constraints than with lead acid.” So electric power is a matter
of horses for courses. Different applications need different solution: cable and the all-singing all-dancing high tech of Li-ion are there; but so is the old dependable lead-acid battery that starts your old-fashioned internal combustion- engined car each morning. Other solutions will doubtless come. The essential is to get away from diesel.
uK firm Falcon Cranes presents the voltpack from Northvolt
UK tower crane supplier Falcon Cranes has launched the Northvolt Voltpack, a modular and scalable energy storage system designed to power cranes and other equipment on construction sites. Northvolt is a battery cell manufacturer headquartered in Stockholm, Sweden.
The Northvolt Voltpack is made up of individual battery modules
that can be combined to provide between 281kWH and 1,405kWh of power. The system works by storing energy from a mains supply or renewable sources in a battery. This stored energy can then be used to power cranes and other equipment on construction sites, reducing the need for diesel or petrol generators. Falcon says the Northvolt Voltpack offers a cleaner and more sustainable way to power cranes and other equipment on construction sites. By reducing the use of diesel or petrol generators, the system can help construction companies reduce their carbon emissions, meet their sustainability targets, help save on fuel costs and reduce noise pollution. Falcon Cranes will be using the Northvolt Voltpack to power their cranes and other heavy equipment on construction sites across the UK. The company is confi dent that the Northvolt Voltpack will help it improve effi ciency, reduce operating costs, and provide a cleaner and more sustainable way to power its cranes. The charging time for the Northvolt Voltpack depends on the size
of the battery module and the charging infrastructure but it typically takes four hours to fully charge the battery on a 125amp supply.
