A fast charging system will allow a lead-acid battery’s energy to replenish quicker than conventional charging methods. Fast charging can be very beneficial, especially for those needing to use their industrial equipment more frequently. It can enable a rapid battery charge, optimize productivity, and minimize downtime due to battery charging requirements.

When selecting a fast charge system that can power a high-demand, multi-shift operation, it’s essential to consider these factors to help you make the best choice.

Control

When choosing a fast charger, it is important to select one that can monitor temperature in real time. Precise temperature control is needed to minimize heat, off-gassing, and battery wear. A fast charge system must be engineered to turn off when the battery gets too hot.

Monitoring

When selecting the right fast charging system, look for a unit that accurately monitors forklift battery voltage and current to avoid overheating.

Equalization

An equalization charge is when the battery is charged at a higher voltage to help remove sulfate buildup and balance the voltage of each cell. An equalized charge is the overcharging of the battery after a complete charging cycle. Find a fast charging system that makes an equalization charge easy, as you may need to perform this frequently.

Start Rate

Finding a fast charging system that allows for the charging process to occur while workers are on break or during short periods when the equipment is not being used is essential for productivity. In general, fast charging replenishes 40-50 amps per 100-ampere hour, which equates to a charge rate of 50% or more.

Flexibility

Lastly, look for a fast charging system with various battery voltage and AH configurations. Having a unit that accommodates diverse charging needs will help prevent the need to purchase multiple pieces of equipment.
