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.

• iBattery-based power battery repair method

• iBattery-based motor control scheme

About iBattery: iBattery is a patented battery connection method featuring redundancy, cell monitoring and dynamic control; each cell can be at 1 (on) or 0 (bypass) state in participating the battery module operation. The iBattery advantages are: insensitive to cell parameter variance; a variable voltage output.

Seeking Strategic Partners

• Focus on NEV after-sale market:

– Operation and Maintenance of Commercial NEV

• Battery testing & data analysis

• Valuable testing services at multi scenarios

– Secondary use of Power Lithium Battery
