Battery Impedance Meters

Ever-changing battery technology requires batteries powering electric vehicles to have high voltage, high power and low impedance. The Battery Impedance Meter, or BIM1000 Series, is capable of measuring up to 1000V of test voltage for simultaneous measurements of both battery voltage and resistance at high speeds. The BIM is the ideal equipment for power battery development research and production tests.

Why Choose a Battery Impedance Meter?

Predictive Maintenance: Unlike a standard voltmeter, an impedance meter can identify a failing battery long before its terminal voltage drops, allowing for replacement before a total system failure occurs.
Non-Intrusive Testing: These meters use an AC signal to measure internal resistance without needing to fully discharge the battery, meaning you can test backup systems while they remain online.
State-of-Health (SoH) Tracking: By comparing current readings against "as-new" benchmarks, you can accurately trend the degradation of a cell over months or years.
Identification of Weak Cells: In large battery banks (like those in UPS systems), these meters quickly pinpoint a single high-resistance cell that might be bottlenecking the entire string.

Core Applications

UPS and Data Centres: Regularly checking the internal resistance of Valve Regulated Lead Acid (VRLA) batteries to ensure emergency power is guaranteed during a mains outage.
Electric Vehicle (EV) Servicing: Assessing the balance and health of individual modules within a high-voltage traction pack to diagnose range loss or power delivery issues.
Telecommunications Power: Maintaining the reliability of remote backup power systems for mobile masts and exchanges where site visits are costly.
Renewable Energy Storage: Monitoring the efficiency of large-scale solar or wind storage banks to optimise the lifespan of the chemical cells.
