Cordless power tool adopts wireless charging solution
The company claims the wireless charging technology meets offers a solution that enables power tools to be used virtually anywhere: in a moving vehicle and between jobs or tasks – with the battery on the tool or off.
"This is a game-changer," explained Hagen Dost, Bosch product manager. "Our new 18 V wireless charging system eliminates the need for a bin of batteries with a partial charge. Now pros can easily charge their hand-held power tools in between tasks or jobs and not worry about dead batteries. This means increased productivity and increased profits."
The power tool uses inductive charging. When the charger is plugged in and the compatible battery is placed on it, the charger begins wirelessly transmitting an alternating magnetic field. The battery, featuring an internal copper coil, acts as a receiver. As the alternating magnetic field penetrates the coil, voltage is induced and a charging current flows to the cells until full. Similar to conventional charging, the battery and charger are in constant communication during the charge process to ensure proper charge and a long battery life.
"Wireless charging opens a whole new world of convenience," said Dost. "And the new wireless batteries are compatible with today’s complete Bosch 18V power tool offering, so users can start benefitting immediately."
Each charger also features Foreign Object Detection (FOD), which detects when any other object besides the compatible battery is on the charging pad. If sensed, the charger will not turn on until the object is removed. This prevents conductive materials, such as bolts, washers, nails or even metal shavings that might inadvertently fall on the pad from heating up. The process is similar to heating coils on an electric stove.
The components of the Bosch Power Ready Wireless Charging System include:
The WCBAT612 is a SlimPack 18 V 2.0 Ah battery that combines the advantages of wireless charging with renowned Bosch battery technology. The battery has a charge-level indicator and is equipped with industry-leading Bosch CoolPack technology, which improves heat dissipation and extends battery life twice as long over packs without it. High-efficiency cells help users maximize productivity on the job by delivering 65 percent more runtime versus 1.5 Ah packs. As part of the brand’s Flexible Power System, the battery is compatible with all Bosch 18 V power tools and chargers for maximum flexibility. Users can expect the addition of the WCBAT620 4.0 Ah 18 V Fat Pack in spring 2015.
The WC18C Wireless Charger will charge the WCBAT612 80 percent in approximately 30 minutes and 100 percent in 50 minutes (from empty) and features charge status indicator lights for easy recognition.
Available with all Bosch Power Ready Wireless Charging System kits, the WC18F frame is designed to mount the charger to workbenches, shelves, side walls or other work surfaces, and serves as a flexible and secure holder for the battery or tool and battery (on horizontal surface).
The Bosch WC18H Mobile Holster offers users the industry’s first customized charging and storage system. Professionals can mount the durable holster to any shelf or side wall for quick and convenient tool charging and storage when they’re on the go or during downtime — no need to remove the battery from the tool. Users can customize how they mount the holster to best fit their work style – vertically or horizontally, on a stationary workbench or in a truck or van – for easy grab-and-go access. Since the tool is always charging when stored, pros are power ready for the entire work day. An enclosed top with three custom inserts secures tool and battery to charger (Bosch Compact Tough and Brute-Tough DD/HDD and Impact Drivers) during bumpy vehicle travel.
