TWS's Success Stories in Electric Vehicles TWS's Success Stories in Electric Vehicles #%SPLIT%#

Case 1: EV Battery System Design

TWS was involved with a US Fortune 500 automotive technology company in an EV design project, with the primary customer located in China. The project was to convert an existing sedan model to pure EV propulsion.

TWS had to design and build the whole battery system within the defined space constraints and had to meet both international and Chinese government regulatory requirements. The battery system developed delivers 40 kWh with a driving range of over 150 km. The thermal management system designed withstands the extreme temperature variations throughout all seasons in China. The battery system works efficiently with the Powertrain and Vehicle Control units provided. The design was completed in three months. The vehicle test run was successful, and TWS's performance was positively recognized by the target Chinese automotive customer.

Case 2: Container Stacking System

Working together with an existing customer (one of the top three equipment companies in China in the construction machinery industry) in an effort to continue to support the Chinese government’s initiative to reduce carbon emissions and recycle energy, TWS was asked to convert a container stacking vehicle from normal diesel engine power to PHEV power.
