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.

10. Testing Issues for Power Battery
1. 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: 0
𝑡
𝐼𝑑𝑡
– 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

14. 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.

15. 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;
