If the capacity of a battery and its voltage are known, then the energy of the battery can be calculated. While the operating voltage range of a lithium-ion battery pack remains relatively constant throughout the lifetime, the capacity begins to decrease gradually already at the beginning of the operation.
It will also increase energy density by 30 percent. The company aims to provide a complete internal battery solution, from conceptualization and prototyping through homologation and production.
The power battery pack box is the core component of the BEV. The power battery pack provides energy for the whole vehicle, and the battery module is protected by the outer casing. The battery pack is generally fixed at the bottom of the car, below the passenger compartment, by means of bolt connections.
This requires a special battery management system (BMS) to monitor the operating state of the battery pack, which is used for battery pack monitoring, calculation, communication, and protection. The BMS is an important part of maintaining the normal operation of the battery system, with special attention to balancing the battery BMS voltage to ensure the
Connecting batteries in parallel keep the voltage of the whole pack the same but multiplies the storage capacity and energy in Reserve Capacity (RC) or Ampere hour (Ah) and Watt hour (Wh).

The efficiency of the electric powertrain is the ratio between the energy output of the battery and the energy output of the motor. A ratio of 100% would mean a perfect conversion of the electric energy into mechanical energy but it is never the case. Many losses happen at different stages in the energy conversion process.
Those changes make it possible to shrink the overall battery considerably while maintaining its energy-storage capacity, thereby achieving a higher energy density. “Those features — enhanced safety and greater energy density — are probably the two most-often-touted advantages of a potential solid-state battery,” says Huang.
