Factors to consider for power batteries in EV
The power battery system added to electric vehicles is large in size and heavy in weight, so it is difficult to find a perfect installation space on the whole vehicle. In the layout of the battery pack, the following aspects need to be considered:First, more power should be arranged in a limited space as much as possible, so as to achieve a longer driving range and reduce the frequency of charging. Any available space is conducive to the improvement of the power of the whole vehicle.Second, the impact of the location of the battery pack on the safety performance of the whole vehicle should be fully considered, especially in extreme cases such as collision, rollover, and fall. Will the battery pack catch fire and explode due to large acceleration or severe extrusion deformation, or will there be parts of the battery pack entering the passenger compartment and causing additional damage.Third, the impact of the weight and shape of the battery pack on the structural life of the whole vehicle should be fully considered, because the weight of the battery pack usually reaches hundreds of kilograms, which brings a large static load and dynamic load to the chassis and suspension of the whole vehicle. Under long-term vibration and impact conditions, it is easy to cause fatigue damage to the mechanical parts of the whole vehicle and reduce the life.Fourth, the heat dissipation conditions of the battery pack should be fully considered, especially under high temperature working conditions and high electrical load working conditions, the battery pack will generate a lot of heat. If the heat dissipation conditions are not ideal or it is close to the heat source, it will cause the battery pack life to decay faster.Fifth, the installation position of the battery pack in the vehicle will also affect the axle load distribution and center of gravity of the vehicle, and thus affect the driving experience and comfort of the vehicle.Bosa EnergyBosa Energy with 150GWH capacity and over 400,000 electric bus/utility vehicle application experience we are listing first 5 in China power battery industry.

BOSA Revitalize the classic Rolls Royce vintage car once again
The Rolls Royce Phantom series, as the flagship product of Rolls Royce cars, has undergone seven generations of evolution since the first Phantom was born in 1925. In 2017, the eighth generation Phantom was officially unveiled at the "Ultimate Masterpiece Exhibition of the Eighth Generation Phantom" in Mayfair, London. Every Phantom embodies the hard work and wisdom of Rolls Royce engineers and designers, using cutting-edge technology and high-quality materials to ensure both vehicle performance and comfort. Until today, there are still a large number of Rolls Royce enthusiasts who are crazy about it. In order to meet the needs of the times, many people choose to use it better through modification, and lithium batteries play a very important role here. We are pleased to see that BOSA’s 105Ah lithium battery module is used in the modification process of this Rolls Royce vintage car. The addition of lithium batteries can provide it with stronger power, allowing this vintage car to run on the road again.

Analysis of lithium battery energy density indicators and their improvement strategies
1. Types of energy density① Mass energy density: refers to the energy stored per unit mass of the battery, the unit is Wh/kg② Volume energy density: refers to the energy stored per unit volume of the battery, the unit is Wh/L2. Factors affecting energy density① Battery materials: The properties of materials such as positive electrode, negative electrode and electrolyte directly affect the battery energy density.② Battery structure: The electrode structure, electrolyte structure, and battery packaging and integration technology will affect the energy density.③ Battery preparation process: The electrode preparation process, electrolyte preparation process, and battery assembly and packaging process also have an impact on the energy density.3. Methods to improve energy density① Improvement of electrolyte and diaphragm: optimize electrolyte performance and improve ion transmission efficiency.② Battery structure design: adopt flattened, thin-sheet design, or multi-electrode structure design, etc. ③ Manufacturing process optimization: reduce active material loss and improve battery capacity and energy efficiency by improving manufacturing process.4.Energy density type selectionWhich energy density to choose depends on the needs of the specific application scenario. If long battery life and light weight are required, then a battery with higher mass energy density will be a better choice. On the contrary, if you need to obtain maximum energy storage in a limited space, a battery with higher volume energy density will be more suitable.
