Shanghai University of Engineering Science (SUES) is
an industrial oriented local university covering new energy
vehicle (NEV) tech and service related areas:
• Auto service: automobile engineering school used to have
a nationally influential auto test center in 90’s;
• Local transportation: ongoing collaboration with the local
public transportation sector (Bus, Rail and Airport);
• Local power industrial: half in the sector are SUES alumni;
• Business: a cruise hospitality program (international cruise
requires a NEV to shuttle to downtown); industrial policy
expert on emergent industrial.
• Battery Lab: new facility for NEV battery testing and R&D.

Testing Issues for Power Battery1. Determination of SOC
• Voltage method:
– Open loop voltage = electric motive force Ɛ
– Close loop voltage = Vc = Ɛ – IR
– When balancing, measured voltage ≠ Ɛ
topology Innovation
• Typical BMS does not measure R real time large current SOC error 20% increased failure rate!
• Current integration method: 0𝑡𝐼𝑑𝑡
– Time cumulated error need regular calibration!
2. Lifetime prediction – Accelerated lab test does not represent driving
condition Test simulating driving profile
– Need “current” + “history” data to predict
Test Scenarios:
• Driving
• Charging
• Test Station
• Lab test

Center’s Goal
The goal is to become a new energy vehicle (NEV) after-sale tech and system integrator within 3 years, bench-marked by leading NEV testing technology and service at multiple application scenarios, with the following specifics:
(1) Establishing a series of NEV testing protocols applicable to multi scenarios, battery repair equipment, battery repair process, systems integration and operational processes;
(2) Solving real problems encountered in the actual operation and maintenance to improve the user experience, establishing the best practice and relevant standards;
(3) Becoming a government recognized public service entity, etc.
Center’s Vision, Mission & Strategies
Vision: NEV replacing traditional vehicles in a sustainable way.
Mission: to provide market-oriented solutions for sustainable NEV implementation. The center’s strategy includes:
(1) R&D: co-develop power battery test related technologies, as a bench-mark after-sale organization for NEV and power lithium battery worldwide;
(2) Platform Development: establishing campus-based G2G car sharing service, so that power lithium battery be monitored real-time, processed in the cloud and an alert will be sent; and to explore joint laboratory or after-sale service base with international partners, etc..
(3) Training: through R&D and platform development to train a team of professional R & D and technical personals;
(4) Standard: Join SAE, TUV and CARTEC in establishing after-sale NEV and power lithium battery standards;
(5) Promotion: via seminar and forum, to form and communicate sustainable solutions for NEV operation and power battery, so that NEV is becoming safer, more reliable and the economy more sustainable.
