BEV Street Cleaner Electric vs. Hydraulic Brush Motors

Background

A BEV street cleaner uses hydraulic motors for the brushes that are shared with a legacy ICE cleaner.  The municipal customer is asking the OEM if it is worth it to switch to electric motors for these brushes on future orders.  

Project Objective

Determine the payback period for investing in electric brush motors for the main and gutter brushes.

ePOP Approach

Model the existing hydraulic configuration and compare it to individual electric motors configuration.  

ePOP Outcome Delivered

Switching to electric motors actually has an immediate payback.  The overall cost of motors ges down because the electric motor used to power the hydraulic pump is able to be downsized.  The efficiency gains of the electric motor allows for a smaller battery, which was not even initially considered.
