Lower voltage batteries result in a higher current for the same level of power and can overheat in intensive work cycles. Conversely, the 350V battery supports high productivity (in tonnes per hour moved) and applications with both intense peaks and continuous heavy-duty usage.
In this case, an electric truck is absolutely tough enough. The Hyster® J7.0-9.0XNL series also features tough drivetrains, simple engineering, longer service intervals, and components built to last the lifetime of the truck, minimising truck maintenance needs.
There is also another important myth to address – that “electric trucks overheat all the time”. The Hyster® J7.0-9.0XNL lift trucks are not only designed with a high voltage (and therefore low current) system that greatly reduces heat development, but also incorporates specially designed water-cooled motors and drive controllers to prevent this, while increasing the overall efficiency of the truck. Battery monitoring systems are also included to keep a close eye on under and overcharging.

A green option for yellow trucks
The Hyster® J7.0-9.0XNL series of electric lift trucks produce zero emissions. This is a clear benefit to those organisations aiming to improve environmental credentials. Globally there is a move towards stricter legislation, and even total bans, on vehicles with IC engines. Organisations are therefore increasingly making the move to electric vehicles.
The ability to run and charge trucks internally without additional ventilation also provides a pollution-free alternative well suited to indoor/outdoor applications. The high controllability of electric trucks makes them an ideal option for working in confined areas, such as narrower aisle widths.
The Hyster® lithium-ion forklifts are also quieter, both when working and when idling, improving operator comfort but also helping ensure that outdoor operations in urban areas comply with noise level legislation, and don’t upset the neighbours!
It depends on the application
It is important to remember that not every solution is right for every application.
Lithium-ion powered electric trucks are a more expensive initial purchase, though they have a long working life and when matched with the right application will offer productivity gains that can offset the cost.
However, low hours and less intensive operations may find the economic benefits more limited. Likewise, operations with high hours and small fleets may find opportunity charging intrusive, and large fleets may struggle to meet peak power demand capacity for charging.
Hyster has the expertise, both in-house and through our trusted dealer network, to advise on the transition from ICE to electrics, the right charging strategies, and ultimately matching the right solution to the specific needs of the application.
