Electric, cordless power tools – climate-friendly and convenient

Simply relaxing in the garden and watching the quiet lawn mower doing the work? Or moving freely without cable salad while trimming your hedge or drilling holes for a shelf? Cordless, electric tools are in trend. Conversely, combustion-powered tools are a thing of the past.

From fueled to electric, from corded to cordless

Combustion-powered tools are a thing of the past. They are noisy and, above all, they pollute a lot. According to California’s Air Resources Board, small gas-powered equipment such as leaf blowers and lawn mowers emit many times more smog-forming pollution than a family car in the same amount of time (e.g. 1-hour leaf blower use ≙ driving 1100 miles). Thus, a new law in California aims to ban the sale of fossil-fueled tools by 2024. Green alternatives are already in place: Cordless power tools equipped with efficient brushless motors and lithium-ion batteries. These alternatives offer the same or even better performance, especially professional power tools from 36 to 72 V. We also see the transition to electric and cordless devices in the DIY sector. In many homes and gardens people use lawn mower and vacuum cleaner robots, or cordless hedge trimmers and drills. These battery-powered devices offer high performance and efficiency at the same time when equipped with modern semiconductors.

One step further: Efficient and sustainable electric devices

Moving ahead, how can semiconductor solutions improve the tools' efficiency and service lives? Let's take a look at the three main areas motor, charging and battery.

Motor control: Today, about 50 percent of all motors are brushed. However, the trend is towards brushless motors that need less battery capacity. Power parts, microcontrollers and sensors enable a much more efficient motor commutation, which results in lower energy consumption and gives the device a longer lifetime.

Charging: Modern chargers not only include better thermal management, which reduces losses during charging and thus needs less energy to charge the same capacity. Today's chargers can also charge batteries smarter and thus extend battery lifetime, so that less battery waste is generated every year.

Battery management: A sustainable device also includes a durable battery. However, this cannot be achieved simply with a bigger battery, since this would require more material and the tool still needs to be handy and light. The solution is power components and modern BMS architecture that extend battery efficiency and lifetime.
