Introduction
The B30 battery box uses LFP as the cathode
material, with excellent safety characteristics. The battery pack is liquid-cooled, has a long
cycle life, good temperature performance, high energy density, low cost, and is
environmentally friendly.
Structure
◆ The battery box consists of 48 C115F
individual cells connected in series using a
CTP scheme;
◆ The top cover is made using low-density, high-strength, fire-resistant continuous
glass fiber fabric prepreg compression
molding process (PCM);
◆ The battery pack has a high energy density.
Features
◆ Single-cell voltage monitoring
◆ Single-cell temperature monitoring
◆ Heating and cooling
Certificates
◆ GB38031/GB3802
◆ R100
◆ UN38.3
