HVS battery, or High Voltage Separator Battery, is a battery system designed for high voltage applications. It is mainly used in electric vehicles (EVs), hybrid electric vehicles (HEVs) and other applications that require high energy density and high voltage output. BYD Battery-Box Premium HVS and HVM are modular high-voltage lithium iron phosphate (LFP) battery packs that can be used with an external inverter.
Working principle of HVS battery:
Battery cell: The battery consists of multiple battery cells, each of which contains a positive electrode, a negative electrode and an electrolyte. The series and parallel combination of battery cells determines the voltage and capacity of the entire battery system.
High voltage design: HVS batteries are designed for high voltage output to improve energy transmission efficiency. High voltage can reduce current, thereby reducing losses in wires and connectors, and reducing heat generation in the system.
Battery Management System (BMS): BMS is used to monitor and manage the performance of the battery to ensure that the battery operates within a safe range. It includes functions such as battery power monitoring, temperature control, overcharge and over-discharge protection to extend battery life and improve safety.
Isolation technology: HVS batteries use high-voltage isolation technology to prevent internal short circuits in the battery and improve safety. Isolation technology can effectively reduce the impact of high voltage on battery components.
Technical features of BYD HVS battery:
High voltage design: BYD HVS battery adopts high voltage design, which can provide higher voltage output, thereby improving the power performance and energy efficiency of electric vehicles. This high voltage design not only improves the power density of the battery, but also optimizes the overall efficiency of the electric system.
Advanced battery management system (BMS): BYD HVS battery is equipped with an advanced battery management system with real-time monitoring, temperature management, charge and discharge control and other functions. These functions ensure the safety and stability of the battery under various working conditions and extend the service life of the battery.
High energy density: HVS battery stores a large amount of electrical energy in a limited space, meeting the application of electric vehicles with high endurance requirements. This high energy density gives BYD electric vehicles a significant advantage in endurance.
Efficient energy recovery: BYD HVS battery supports an efficient energy recovery system that can recover energy during braking and deceleration and store it for subsequent driving. This design helps to improve the overall energy efficiency and economy of electric vehicles.
Safety: HVS battery adopts high-voltage isolation technology and multiple safety protection measures to effectively prevent battery overheating, short circuit and other faults, ensuring safety during use.
