Design of lithium-ion battery management system for mine electric vehicle

Abstract

With the continuous improvement on mine equipment automation level and the progress of battery manufacturing technology, Lithium-ion batteries are widely used in mining transportation, monitoring communication and emergency facilities. This paper designs a kind of lithium-ion battery management system for explosion-proof mining electric vehicle according to GB3836-20210 series standard. And the management system takes STM32F103 as the main controller and LTC6811 as the core, using passive equalization strategy to realize battery voltage equalization. The test results show that the maximum error of 100 batteries after equalization is 0.32v, the average error is 0.03v and the maximum error between the monitoring value and the measured value is 0.3v, the average error is 0.0019v, which prove that the management system has high accuracy and effectiveness.

Deciphering Advanced Sensors for Life and Safety Monitoring of Lithium Batteries

“…So, here mainly discussed thermistors based on negative temperature coefficient materials. Thermistors are powerful thermal sensors used in pouch-type battery, [72] cylindrical-type battery, [52] battery packs, [73] etc. Similar to thermocouples, the negative temperature coefficient temperature sensor is a kind of point type sensor, [72] which could not realize a temperature gradient measurement.…”

Yeni Nesil, Modüler ve Akıllı Batarya Yönetim Sistemi

“…Bunların dışında bataryalı patlayıcı yükleyiciler ve bataryalı LED ışık kuleleri madenlerde kullanılmaktadır (Ertugrul et al, 2020). Madenlerde çalışmak üzere tasarlanmış elektrikli raylı araçlara özel batarya yönetim sistemleri de geliştirilmiştir (Huang et al, 2021).…”
