    CTEK: Battery Know How and Management CTEK: Battery Know How and Management Presentation Transcript

    • Battery Know How and Management
    • Benefits of Battery Management
      • With effective battery management
        • Reduce ‘warranty ‘ handling costs
          • Replacements, call outs, uncharged labour
        • Reduce end user downtime
        • Maximize equipment productivity
        • Increase customer satisfaction
        • Longer, more effective battery life
        • A better environment
    • Desired Outcomes
      • At the end of this session I hope to have shared with you
        • How a lead-acid battery works
        • Different lead-acid battery types
        • Battery problems and their causes
        • effective battery charging method
        • ideas and practical experience on how to improve dealer and consumer battery experience
    • CTEK – Battery Charger Specialists.
    • ‘ The Smartest Battery Chargers in the World’
    • CTEK Brief History
    • Battery Knowledge
    • Purpose of the Battery
      • Despite many developments in Lead Acid batteries the functions remain the same
        • Provide starting power
        • Power accessories when engine off / idling
        • To stabilize charging voltage
        • Smooth voltage spikes
        • Absorb voltage surges
    • Basic Battery Construction
      • Batteries are made of five basic components:
        • A resilient plastic container. (1)
        • Positive (lead dioxide)and negative (sponge lead) plates.(2)
        • Plate separators.(3)
        • Electrolyte, a solution of sulfuric acid and water ‘battery acid’. (4)
        • Terminal Posts,the connection point between the battery and whatever it powers. (5)
    • The Battery Cycle
      • Battery Discharge
        • providing voltage source for load
        • electrolyte has high sulfuric acid content when highly charged
        • acid reacts with plate material to create current
        • acid content of electrolyte reduces
        • If reduced too far results in ‘flat’ or deep discharged battery
    • The Battery Cycle
      • Battery Discharge
        • providing voltage source for load
        • electrolyte has high sulfuric acid content when highly charged
        • acid reacts with plate material to create current
        • acid content of electrolyte reduces
        • If reduced too far results in ‘flat’ or deep discharged battery
      • Battery Recharge
        • external voltage (pressure) created to push current (amps) in to the battery
        • acid forced out of the plates and back in to electrolyte
        • If not correctly controlled will lead to undercharge or overcharge
    • The 12V Battery
      • Six cells of 2.12V Each
      • Effective battery operation only at 12.45V+
      • Readings below 12.4V require immediate corrective action to avoid ‘deep discharge’ and associated recharging problems
      Battery Open Circuit Voltage vs. State of Charge 12.72V 100% 12.45V 75% 12.24V 50% 12.06V 25% 11.89V 0%
    • Battery Types- Summary
      • Robust
      • High self-discharge
      • High water consumption
      • Low self-discharge
      • Low water consumption
      • Should not be discharged more than 50% due to stratification
      • Low self-discharge
      • No water consumption
      • Deep-cycle – highest # of cycles
      • Low self-discharge
      • No water consumption
      • Deep-cycle – many cycles
    • Battery Types and Applications 3 10 30 100 300 Size [Ah] 14-28Ah
    • Battery Problems
    • Most warranty returns are just undercharged! 178 returns evaluated Today ’s problems
    • Battery Problems – Seasonal Use Equipment
      • No1 failure reason for Ride On ’s
      • Often batteries undercharged at point of delivery – resulting in battery failure within a few weeks
      • Charging equipment unable to recover / restore batteries
      • Long periods of inactivity
      • Exposure to temperature extremes in use and in storage
      • Regulator / alternator unable to charge batteries to full capacity
    • Battery Problems and Causes Sulphation Overcharge / Fluid Loss Stratification
      • Undercharge (recovery from deep discharge, charging system)
      • Overcharge(charging system)
      • Temperature extremes
      • Parallel loads
      • Inactivity (seasonal use)
      • Lack of battery awareness at all levels
    • Effective Charging
    • Battery Charger Evolution Linear Basic Linear Automatic Intelligent Intelligent multi stage
    • Battery Problems and Solutions Sulphation Overcharge Stratification Desulphation Charge control Recondition SOLUTIONS
    • The CTEK Approach – Total Control = Voltage = Current Desulphation Analyze Soft Start Pulse Absorption Float Bulk Recondition
    • CTEK Technology Promise
      • The safest, most effective way to
        • Recover batteries
        • Charge batteries
        • Maintain batteries
      • Maximise battery life
      • Reduce operator costs
      • Ensure vehicle reliability
    • Practical Steps in Battery Management
    • Comfort Indicator Green: (≥12.7V) Battery fully charged Yellow: (<12.7V - ≤12.4V) Charging battery recommended to avoid stratification Red: (< 12.4V) Charging of Battery needed to ensure starting and avoid sulphation
    • Usage Tips
      • When connected to the charger, the Comfort Indicator flashes green regardless of the charge status of the battery
      • The battery needs 30-60 minutes to ‘settle’ and to be able to show the true state of charge on the Comfort Indicator status lights.
      • For the Comfort Indicator to give an accurate reading of battery status the battery itself should not be in use. (Ignition off)
    • Comfort Indicator Variants
    • Case Study – Car Showroom
      • Problem
        • Battery discharge due to repeated demonstrations of vehicle accessories
      • Solution
        • Showroom charging programme using CTEK charger and Comfort Indicator
      • Results
        • Battery warranty returns on newly supplied cars almost eliminated
      • Used by VW, Audi, Porsche, Skoda
    • Audi Promotional Display
    • Thank you for your attention
