How to prevent expensive peak currents

Selectiva battery chargers are actively preventing peak currents

At the end of a shift, all forklift trucks are driven back to their charging stations and their batteries are charged at the same time. This leads to increased energy consumption - especially at the start of the charging process - which can result in expensive peak currents. Should this occur on a regular basis, consumption will exceed the annual quota agreed with the energy supplier. Expensive supplementary payments due to the additional consumption and supply costs will surely follow. Many companies respond by disconnecting production machines or even entire warehouses and production areas from the grid and shutting them down when peak currents occur. Disruptions to the company's entire operations can thus be traced to the simultaneous peak current consumption of the battery charging systems.

delayed charging start

The “delayed charging start” feature enables users to set the time at which the charging process begins, allowing individual charging processes (and thus the energy consumption) to be spread out over time so that peak currents do not occur. The start of the charging process can also be controlled using the calendar function on the battery charging systems. The user can set the desired charging start time on the device, irrespective of when the battery is connected.

Operators of large forklift truck fleets are able to start the charging process in individual departments or charging stations at different times, for example every 15 minutes. By avoiding the simultaneous peak current consumption of the battery charging systems in this way, energy costs are reduced.

Fully charged by a given time

With the function "fully charged by a given time" the time at which the batteries have to be fully charged is set. This enables a gentle and slow start of the charging process. The time available for charging of the batteries is used in the most efficient way. Elongated charging process limits the heating, this way the charging process is gentle to the battery. This has two major benefits: energy savings and extension of the battery life.

Prolonging battery life

The bigger the battery, the bigger the investment: the traction battery is a significant cost factor when purchasing a forklift truck system. However, the service life of the battery is crucial for the cost-effectiveness of the overall three-part system (forklift truck, battery and charging technology).

Lowering energy costs

Reducing energy costs is a top priority for many companies, be it to reach company-wide benchmark values concerning the efficiency of a site, to ensure that operating costs remain constant even when turnover is higher and electricity prices are increasing, or due to incentives offered by energy suppliers, such as attractive tariffs for clients using energy sparingly.

Standards-compliant charging installations

Charging stations and rooms must comply with numerous standards and regulations: a dry, frost-free and cool environment is equally as important as sufficient ventilation and fire and explosion protection measures.
