This is an image familiar to many smartphone users. The phone's battery can still be used for a few percentage points - so before you leave home, it needs to put it on the charging board for a few minutes and charge it by induction. No plug, no cable, no time to waste. Fast power supply is also an advantage of induction charging for lithium-ion forklifts, tractors and automatic guided vehicles (AGVS). The so-called "in-process charging" is becoming more and more important in internal logistics.
Compared with plug-in or ring connection, its advantages are obvious because manual intervention is no longer required. Take the pull rod train as an example. Under the traditional charging mode, when the battery power is low, the towing vehicle must be untied by the employee and charged. In some companies, for the sake of occupational safety, this is carried out outside the hall. During this time, the vehicle is not productive - personnel are also tied to the charging process.
Start charging in one second
Based on the principle of electromagnetic induction, the intelligent point charging system can realize high current and short midway charging. In short: "charging" can realize full-automatic charging during the "working hours" of the vehicle. You only need to drive the vehicle to the pre installed charging board. One of the providers of this innovation is wiferion, a leading solution provider of mobile wireless energy supply for electric industrial vehicles. Thanks to the technology of Freiburg start-up company, the energy level of forklift and lifting equipment has always been maintained at a high level. The battery used may be much smaller than that in the charging process using a plug connection, and the expensive load peak during charging has become a thing of the past. Charging technology can be installed at frequent points in the logistics environment, including loading and unloading or picking points.
It is similar to placing the mobile phone on the charging board, which can start charging in less than one second. These devices provide a 40 mm positional tolerance in all directions so that the operator can quickly charge the vehicle when unloading - without actually realizing it. This increases availability by 30% and allows the vehicle to operate 24 / 7.
Flexible and adaptable
There is no need for cost intensive intervention in the infrastructure like the permanently installed AGV guidance system, because there is no need to lay cables on the floor - once the appropriate charging location is determined, the fixed transmitter unit is installed with a so-called wallbox and charging board; The receiving electronics are located in the installed battery tray. If the size of the route, charging point or hall changes, more wall boxes can be moved or added. Existing vehicles can also be retrofitted with lithium-ion batteries.
