D-Broad
The Revolution in Charging Systems

The Revolution in
Charging Systems

  • Japanese technology realizing 100% charging rate success
  • Magnetic resonance system allowing long-distance power transfer*

*Daihen is an official WiTricity licensee

Through the combination between the electric energy specialists DAIHEN and the patented coil technology of Electricity, D-Broad allows for an charging area that is unchallenged in its width. It allows for wireless charging with a maximum gap of 40mm for power receiving & transmission, while the AGV can be stopped with a gap up to 10mm. D-Broad has a charging success rate of 100% (a charging failure = stoppage of the AGV). Until now, a charging failure complaint has not been registered from any of our customers.

DAIHEN + WiTricity = D-Broad
Unparralled Safety & Productivity

Unparralled Safety
& Productivity

  • Realizing 24-hour operation without labor needs
  • High-speed charging of max. 60A*
  • Easy to install to existing AGVs

*Through utilizing of an optional capacitor

CAPACITOR UNITCAPACITOR UNIT

By simply inserting our technology to the AGV to be charged as well as installing a charging point at the AGV's stoppage area, there is no need to purchase a specialized AGV. Adopting our capacitor allows for high-speed transfer of power, meaning that by installing charging coils at a position where the AGV is unloading can lead to seamless charging during the unloading process. This also eliminates the need for daily charging, battery replacement as well as trouble from the occurrence of electric shocks.

Accumlated cost graph

Initial investment and annual running costs largely vary by the combination of charging system and power storage device.
Requirements for estimate workload:
9 large AGVs (wired charging through changing the battery) equivalent to $26,500
Operating time:
In 8 hours, 3 substitutions are necessary
Number of power transfer units:
4 sets/9 units

DAIHEN's wireless power transfer system for AGV (a solution that combines the wireless power transfer system with a capacitor) ensures payout within two years.

Cutting all energy-related costs

Achieving Real
Cost Reduction

  • Cutting energy-related costs at your factory or warehouse
  • The industry's highest standard for wireless charging efficiency
  • More efficient than wired solutions
86% charging efficiency

In the development process, DAIHEN has achieved advances in power transfer resulting in an increased charging efficiency from below 50% to above 86%. Even with some gaps in positioning, charging efficiency of 86% was maintained.

Power savings of 26%

By using a capacitor unit together with the power storage device, a reduction in energy loss of 26% is possible. There have also been cases where a yearly reduction in electricity costs and CO2 emissions of up to 60% were achieved.

YOSHINORI TSURUDA

At DAIHEN, we are proud to have been able to develop the world's first magnetic resonance wireless charging system for industrial applications, through which we believe the modern factory will be revolutionized. We released our wireless charging system for AGV use in April of 2016 and have been overwhelmed by the positive reaction - on a global scale - from our customers. Our next mission is to expand our lineup for wireless charging solutions further, with various target applications including electric vehicles in planning.

TESTIMONIALS

Revolutionizing Manufacturing Sites, 1 by 1

"We could not be more pleased with our decision to install 2 types (standard-type and slim-type) of DAIHEN's D-Broad CORE at our Okayama factory, a decision we came to with the goal of increasing production capability as well as realizing increased automation.
Through implementing the capacitor unit as a power storage device, we achieved high-efficiency, high-speed charging during the AGV's operation. Furthermore, this eliminated the need for daily manual charging, as well as the need to change deteriorating lead-acid batteries.
Implementing D-Broad helped us achieve our goals with respect to factory automation and improved productivity, with an added bonus of being environmentally friendly."
