Monitoring State-of-Charge
The BMS attempts to report how much usable capacity the battery has remaining, which can be a complex function affected by a variety of factors, including ambient temperature and the age of the battery.
Battery Management Software
Battery Management System (BMS) in EV's
Electric vehicles (EVs) represent a transformative shift in the automotive landscape by replacing traditional internal combustion engines with electric motors for propulsion. These motors are powered by rechargeable battery packs, which store and supply electrical energy to drive the vehicle. At the heart of this energy system lies a critical component: the Battery Management System (BMS).
A Battery Management System is an advanced electronic control unit that monitors, regulates, and safeguards the battery pack in an EV. It ensures optimal performance, maximizes battery life, and protects the system from potentially dangerous conditions.
Roles of Battery Management Systems in Lithium-ion Batteries
Most lithium-ion batteries used in EVs are equipped with a BMS, due to the inherent risks associated with overcharging, over-discharging, overheating, or damage. The Battery Management System for electric vehicle protects the battery from various hazards by limiting the charging and discharging currents, maintaining the optimal temperature range, and balancing the cells to prevent uneven degradation. The Battery Management System for electric vehicle also optimizes energy utilization and prolongs the battery life by preventing excessive cycling and deep discharging.
What Is a Battery Management Software (BMS)?
Battery management software (BMS) is a critical application for electric vehicles that monitors an EV’s battery to achieve the highest possible performance, increase the battery’s longevity and provide essential safety functions.
The BMS has three primary core functions:
The battery is the largest, heaviest, and most resource-intensive and expensive component of an electric vehicle, and sophisticated BMS is required to optimize that investment.
Reducing Degradation
Every charge and discharge cycle impacts the health of the battery. However, there are several variables that can be controlled to mitigate battery degradation. Managing charging speed and balancing the charge among individual cells go a long way toward optimizing charging performance and battery health.
Issuing Anomaly Alerts
In the event of overheating within a battery cell, the BMS detects the temperature change and makes a split-second decision about whether to shut down the battery and alert the vehicle operator to the issue.
