Battery charger technology by BMASS
BMASS is licensed to manufacture and distribute a pulsed switch mode
battery charger, 'Smart Charger'. The Smart Charger is a portable battery charger that:
- cannot overcharge or damage batteries if left on indefinitely,
- eliminates gassing due to overcharge,
- can fully recharge a 40AH battery in under 5 hours (ordinary chargers require up to 16 hours),
- rugged and robust construction,
- ideal for situations where the charged battery must be kept on float.
The charger is suitable for charging lead acid batteries, either recombination electrolyte
(GEL) type or normal vented batteries. The charger offers the benefits of rapid charging,
and at the same time is safe to use as a float charger.
The charger provides two rates of charge: a regulator, and a constant potential charge for
float use. The two rates of charge alternate every 10 seconds approximately, and the charge
current in the constant potential mode is used as a measure of the state of charge of the
battery. If this current is below about c/400, the battery is assumed to be at or near full
charge, and the high rate charge is disabled. Both Recombination Electrolyte batteries and
normal vented batteries benefit from this treatment. Overcharge is impossible with this
charger and a serviceable battery.
The charger is fully protected against short circuit or reverse connection, and is additionally
thermally protected. For cyclic discharge use the charger can be internally set 14.0 to 14.1 V DC
constant potential output.
