information to the local monitoring system and control the PCS to stop the system operation.<\/p><p>If the PCS does not respond within the specified time, the battery management system controls the system to stop the operation of the energy storage battery unit to ensure the safety of the system operation.<\/p><p><strong>BMS online passive balance<\/strong><br \/>During the mass production of single batteries, due to natural fluctuations in raw materials and production processes, the capacity, internal resistance, voltage and self-discharge rate of single batteries will have certain deviations.<\/p><p>During use, with the increase of the number of charge and discharge cycles and the influence of storage time and temperature, the capacity attenuation of the single battery will also be inconsistent, resulting in the inconsistency of the single battery in the same battery string, which reduces the capacity of the entire BYD energy storage battery unit.<\/p><p>Therefore, it is necessary to balance the battery to improve the consistency of the battery. The battery equalization device performs discharge equalization by the BMU. The discharge equalization circuit connects the discharge resistor in parallel with the battery cells through the battery gating switch, and realizes the battery discharge balance by discharging the battery cells.<\/p><p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-112392\" src=\"https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/09\/BYD-lithium-iron-phosphate-battery.webp\" alt=\"BYD-lithium-iron-phosphate-battery\" width=\"1000\" height=\"500\" srcset=\"https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/09\/BYD-lithium-iron-phosphate-battery.webp 1000w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/09\/BYD-lithium-iron-phosphate-battery-300x150.webp 300w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/09\/BYD-lithium-iron-phosphate-battery-768x384.webp 768w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/09\/BYD-lithium-iron-phosphate-battery-600x300.webp 600w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/p><h2 id=\"byd-lithium-iron-phosphate-battery\">BYD lithium iron phosphate battery<\/h2><p>The lithium iron phosphate battery used in BYD energy storage system can meet the demand for megawatt-level power output.
