Continuous monitoring of hydrogen gas at lead acid battery charging stations

Equipment powered by lead acid batteries, such as forklifts used in a warehouse, have heavy duty battery banks that are commonly lined up in an indoor charging station formation where many machines can be charged at one time. Lead acid batteries produce flammable hydrogen gas as part of the normal charging process. The amount of hydrogen that is produced varies depending on the size and number of batteries and can increase with overcharging, excessive heat and other factors. As the hydrogen level builds, the risk of fire and explosion increases which is a serious safety concern.
