Forklift battery charger
Multi voltage forklift battery charger
Microtex offers forklift battery charger power requirements meeting European norms.
How do you charge a forklift battery?
Forklift battery chargers must be selected to match the Ampere hour and voltage of the battery. Selecting the right charger is very important for the performance and the life of the forklift battery.
The charger must be reliable & must be capable of:
- Limiting the temperature rise while charging
- stopping current at the right time, without overcharging
- Equalization charge
Create a separate area for charging & comply with all statutory regulations for the hazards involved in handling batteries, battery acid & battery chargers. Only trained people should undertake the charging of batteries.
Battery charger forklift charging procedure:
- As soon as the forklift battery is received for charging, the time of receipt and (open circuit voltage) OCV readings are recorded in the relevant log sheets.
- If there is a metal cover top for the forklift battery, it should be kept open
- The events are removed and replaced loosely over the vent holes.
- Using a multi voltage forklift battery charger, the proper charger setting is selected, and the charging clips are correctly connected to the battery terminals.
- The appropriate charging current is set, and charging commenced.
- Hourly readings of the terminal voltage, specific gravity and temperature of the electrolyte are recorded with suitable measuring means.
- Charging may take about 8 to 12 hours.
- If the battery electrolyte is warm, provide a fan for cooling purpose; exposed metallic parts like inter-cell connectors help in bringing down the temperature of the electrolyte
- The final on-charge voltage may reach about 2.6 to 2.7 V per cell.
- At this stage, copious gassing can be observed in all the cells. This is due to the high rate of water electrolysis occurring at these voltage values.
- Now, the charger can be put on finishing current mode (4 to 5 A per 100 Ah)
- The gassing should be uniform in all the cells
- After continuing the charge at the finishing rate for 3 to 4 hours, charging can be terminated.
- Before switching off the charger, all reading should be recorded.
- The top of the battery must now be cleaned well, first with a wet cloth and then with a dry cloth.
- The charging clips are disconnected.
- The battery is allowed to cool down. If the battery is required urgently, and there is no time for cooling, follow the procedure described above.
- If the temperature of the electrolyte is too warm (more than 45°C) and the area in which the forklift is operated also warm (as in foundries), it is best to have two sets of batteries for one forklift where the forklift is used in busy loading stations.

Traction batteries are an expensive part of an electrically driven vehicle. Reliable and efficient charging equipment correctly matched to battery capacity and required recharge times are a basic necessity for operational effectiveness and optimized battery life and performance. Two charging technologies can be used to achieve this goal: WoWa chargers and HF chargers.
Conventional WoWa chargers offer a reliable and robust way to charge conventional traction batteries. They are cost-effective charging systems for traction applications where a 12- to 14-hour recharge time is appropriate. Their robustness comes at a cost, however: efficiency is only 75%.
High-frequency chargers use switch-mode technology, allowing for a better power factor, increased efficiency and low DC ripple. Reduced energy consumption (15%) and extended battery life (15%) are the result.
50 Hz Chargers
Classic 50 Hz chargers are also referred to as linear or ferro resonant chargers. A transformer and rectifier transform the input AC voltage into a lower voltage DC. Voltage fluctuations at the primary (input) side are passed on to the secondary (output) side, causing a ripple that is detrimental to any VRLA battery.
The efficiency of a 50 Hz charger is about 75%. That is, 25% of the energy used is lost as it is converted into heat.
High-frequency Chargers
The input mains voltage is rectified and then converted into a high operating frequency (50kHz) by a high-frequency chopping circuit. This high-frequency input is then passed through a transformer and rectified to the correct DC voltage with only a negligible ripple. Because of this high frequency, the transformation can be done with a small ferrite transformer. This makes HF chargers suitable for all types of lead-acid batteries.
High-frequency chargers have an efficiency of over 90%, which makes them very cost-effective. Because an HF charger does not have a heavy transformer, its weight is generally a quarter to one-fifth of that of a similar conventional charger. This allows for wall mounting, thus increasing floor space and safety.
Microprocessor-controlled chargers
A charging voltage of 13.8V is sufficient to charge a battery without causing damage by overcharging. This is exactly what simple (and therefore cheap) chargers do. Unfortunately, the battery will not attain more than 75% SOC (state of charge).
Microprocessor-controlled chargers’ control both the current and the voltage they provide when charging a battery. This is done in several steps, taking into account battery condition and often even ambient temperature, thus allowing maximum charge without causing any damage. Temperature-controlled charging is especially important for gel batteries.
Hybrid Chargers
Chopper chargers use ferro resonant transformers combined with switching technology at the secondary end. This allows for very high charging rates: a traction battery can be charged in as little as one hour – albeit reducing battery life cycle by 30%.
This solution enables multi-shift operations without spare batteries and battery changing. In terms of safety time and total cost of ownership, the combination of an expensive chopper charger plus one battery pack versus one HF charger and two battery packs is an alternative that should be seriously considered.
