This article reviews the evolutions and challenges of (i) state-of-the-art battery technologies and (ii) state-of-the-art battery management technologies for hybrid and pure EVs.
What is battery management system (BMS) in electric vehicles?
The Battery Management System plays several critical functions in electric vehicles, as in the following pointers. The BMS board fetches real-time data on fundamental battery parameters like voltage, temperature, and current.
Why is battery management important for EV batteries?
On top of batteries, battery management is crucial to ensure the reliable and safe operation of EV batteries. During the charge/discharge cycling, it facilitates the batteries to exert their optimal performance and prolong their service lives.
There are five main functions in terms of hardware implementation in BMSs for EVs: battery parameter acquisition; battery system balancing; battery information management; battery thermal management; and battery charge control.
How does the battery management system for electric vehicles work?
Currently, the battery management system for electric vehicles increasingly leverages wireless communication protocols. This allows for rapid system enhancements through Over-the-Air (OTA) updates. This enables system enhancements to be delivered rapidly through Over-the-Air (OTA) updates.
How does a traction battery management system work?
Overheating: By regulating the thermal management system, the BMS prevents thermal runaway, a condition that can lead to battery fires. Overcharging and Over-discharging: The BMS ensures that each cell in the traction battery operates within its safe voltage range during EV charging and use.
What types of batteries are used in electric vehicles (EVs)?
This blog discusses the Battery Management System's (BMS) significant contribution to Electric Vehicles (EVs). So, when it comes to the types of batteries used in electric vehicles (EVs), the most popular ones are lithium-ion batteries. They've really taken the spotlight because they offer a great balance of energy density, lifespan, and weight.
