Battery Management System Technology

1) Major

Team Major:

core team should be composed of strategic, technical, financing and sales key personnel. To make automotive electronic products, one must endure humiliation, torture and loneliness!

technology major:

BMS involves the intersection of automotive electronics, electrical, high-voltage power, machinery and other disciplines, and requires high experience and innovation ability of technical teams and developers.

Service Major:

service requires all aspects of vehicle control, charging, electrical control, etc. On-site service is more comprehensive and coordinated with BMS as the center.

currently exists:

cell factory does BMS, PACK factory does cell, is not the most professional. Professional innovation, avoid homogeneous development, the current battery factory PACK personnel frequent flow, technological progress is slow.

(2) Focus

Focus on BMS:

BMS is an important electronic and electrical equipment to ensure the stable operation of power battery packs. It contains many key technical points and has become an industry. It is not the threshold to be used, but the threshold to be safe and reliable.

Focus on Customer Value Embodiment:

the current power lithium battery systems and models are different, how to develop BMS with different matching degrees according to the characteristics of different cells to ensure the best application effect after the cells are grouped, so as to cope with the shortening of cruising range, the rapid attenuation of cycle life, and frequent safety accidents.

Focus on Open Cooperation:

BMS is the core link of battery core, grouping, vehicle and charging. Only more open cooperation can promote the development of core components of electric vehicles.

, we welcome the whole vehicle factory and battery cell factory to cooperate to promote the development of key parts technology and industrialization of domestic electric vehicles, so that the development of electric vehicles really comes from China core.

5, what is the ISO26262?

functional safety: the system does not have unreasonable risks caused by electronic and electrical functional failures.

(2)ISO26262 guarantee

(3)ISO26262 application

international standard ISO26262 aimed at improving the functional safety of road vehicles was officially promulgated at the end of 2011 and has attracted extensive attention from domestic and foreign enterprises. International automobile manufacturers (BMW, GM, Ford, etc.) and auto parts suppliers (Bosch, Delphi, etc.) have already adopted this standard to develop safety-related electronic and electrical products, which are used in the development of hybrid vehicles and electric vehicles.

adjusted the structure of the company's research and development department in March 2014 to conform to functional safety and development processes, and to improve and strengthen the control and management of functional safety.

the battery management system of BMW electric vehicle i3 has reached the ISO26262 ASIL D and Tesla's battery management system development also meets the requirements of the ISO26262.

the future, the influence of ISO26262 on the electric vehicle industry far exceeds the TS16949 of the traditional automobile industry.
