HEV hybrid battery unit specification
Thank you for choosing our NCM series power battery unit products, this manual will introduce the basic performance, parameters, and the use of installation precautions in detail, to help you better understand the use of this product.
The NCM high power cell unit uses aluminum substrate with better thermal conductivity, combined with high thermal conductivity silicon wafer. The high power characteristics of the NCM and the high energy characteristics of lithium-ion batteries. Optimize material and electrochemical system, adopt full pole ear laser welding technology to realize the design advantages of ultra-low internal resistance, ultra-high reliability and thermal management safety structure; based on the external characteristics of linear charge and discharge curve, SOC and charging control management is very accurate. By adjusting the surface capacity and the N / P ratio, the positive and negative electrode potential is optimized to avoid negative lithium precipitation, and the core is essentially safer in the charge and discharge process. It is widely used in power drag, kinetic energy recovery, 12 / 24V emergency start, 48V light hybrid MHEV, high voltage HEV, FCEV and other vehicle markets.

8. Schematic diagram of the lithium battery unit assembly:
two. Installation 1. Removaentdheuosraiggineal vehicle battery pack assembly as shown in the figure:
2. After removing the housing, the battery unit is obtained as shown:
3. Remove the guide plate of the BUS bus and the bottom fixing screw of the core preferentially as shown in the figure:
4. After the above steps, start to measure the NCM cell voltage. Note that the short circuit of the battery element; the voltage difference of all cell cells is within 50 mV for the new battery cell replacement. If the voltage difference exceeds this value, please contact the local dealer for replacement. 5. According to the arrangement form of the original battery cell, restore the installation to the original arrangement state. The pole column of the battery cell is made of copper, and the conductivity is more Good, but the material is relatively soft with iron, so it is necessary to pay attention to the installation torque of the guide plate is about 25~28 Kgf · cm(2.5~2.8 N·m). At the same time also need to combine the battery under the fixed nut gradually lock, avoid a twist in place type, and to combine the guide screw up first (not twist), and then to twist to 60% at the bottom of the screw, slightly shaking the battery module, until the guide all free contact, under the condition of no external stress repeat back and forth several times gradually twist. The wiring harness total The tie belt is stuck, the temperature probe is slightly different according to the model, but also according to the original position back.
6. After all the final installation and inspection, the packaging shell can be completed.
