Lithium-ion Batteries for Commercial Vehicle

The Flexi battery pack is our standard pack and is a mass production battery and assembly in the commercial vehicle projects in China's local market, therefore the quality has been verified through a series of Chinese National Standard for electric vehicles application and actual operation. Additionally, the Flexi pack has been certificated by MSDS and UN38.3, so will not have any international transportation issues. Compared with a customized battery pack, the Flexi pack has a competitive price advantage and also saves the certification and development costs by being a ready-to-go proven product.

Flexi Pack is active cooled.

Waterproof and dustproof performance

Rechargeable energy storage system, including 4pcs aspects:

• The rechargeable energy storage system should be equipped with maintenance switches and fuses.

• The battery pack should be equipped with pressure balance devices, and the pressure relief is not be greater than 50 kPa.

• Cell thermal runaway test: no fire or explosion occurred during the heating process and within 1 hour after the heating.

• Battery pack thermal runaway test: the sample was heated to conduct thermal runaway expansion test. No external fire or

  explosion occurred within 5 minutes after the signal of thermal accident was sent out.
