  • What types of monitoring and recording devices are suited for high rate charging?

    What types of monitoring and recording devices are suited for high rate charging?

    Jun , 20 2022
    The higher the charging rate, the more critical it is to monitor the charging process to prevent permanent capacity loss. In efforts to preserve battery life, Fast and Opportunity charging incorporates a method of monitoring battery electrolyte temperature and/or internal resistance and adjusting charging current as necessary. Although these monitoring devices can have a very positive impact on ba...
