The Rosenbauer BEST (Battery Electric Safety Tool) is a specialized tool designed for use by emergency responders in the event of an accident or other emergency involving an electric vehicle (EV).

The BEST tool is designed to provide a safe and efficient way to disable the high-voltage electrical system in an EV, which is important because the high-voltage system in an EV can pose a serious risk of electrocution if it is not properly isolated and de-energized.

The BEST tool is a handheld device that incorporates a number of safety features to protect both the operator and the vehicle. It is designed to be used in conjunction with the emergency plug or service disconnect found on most EVs.

The BEST tool uses a unique plug-and-play system that allows the operator to easily and safely connect and disconnect the tool from the emergency plug. The tool also features a built-in safety mechanism that prevents the high-voltage system from re-energizing once it has been disconnected. In addition to its safety features, the BEST tool also includes a number of other functions designed to assist emergency responders in extricating occupants from an EV.

These functions include a cutting blade for removing seat belts, a glass-breaking hammer, and a flashlight for illuminating the interior of the vehicle. Overall, the Rosenbauer BEST tool is an innovative and effective tool for use by emergency responders in the event of an accident or other emergency involving an EV. Its combination of safety features and extrication functions make it a valuable addition to any EV extrication kit.
