Global glacialtech

17, August 2010, Taipei, Taiwan – GlacialTech Inc., a diversified provider of CPU coolers, power supplies, LED products etc. for industrial and commercial realms, introduces a distinctive series of mini battery chargers – ML30, MM30, and MF30 respectively applicable to Lead-Acid, Lithium Manganese Dioxide (LiMnO2), and Lithium Iron Phosphate (LiFePO4) batteries generally installed in hand tools (e.g. electric screwdrivers), household appliances (e.g. vacuum cleaners), and gardening tools (e.g. lawn mowers).

The ML30, MM30, and MF30 battery chargers incorporate an intelligent microcontroller to monitor and supervise the whole charging process. A three-stage charging procedure implemented in the ML30 series is suitable for charging Lead-Acid batteries; a two-stage charging procedure implemented in the MM30 and MF30 series is suitable for charging Lithium Manganese Dioxide and Lithium Iron Phosphate batteries. The charging time is well controlled to prevent batteries from overcharging and overheating. The ML30, MM30, and MF30 battery chargers also feature bicolor LED status display, short-circuit and reverse-polarity protection, a fanless and dustproof design to get rid of noise and dust as well as compliance with safety regulations including UL, CE, TUV, etc. The most attractive part is these small-size and light-weight ML30, MM30, and MF30 battery chargers are very easy to carry.

Features:
- High efficiency (>80%)
- Embedded microcontroller
- Fanless and dustproof design
- Safety approvals: UL, CE, TUV
- No spark during connecting or disconnecting the charger and the battery
- Robust protections: short-circuit, reverse-polarity, over-temperature, over-charge

Uniqueness:
Prevailing over conventional battery chargers with relatively simple circuitry and rough functions, all the hi-tech ML30, MM30, and MF30 battery chargers incorporate an intelligent and versatile microcontroller to detect the battery disconnection, coordinate and dominate the whole charging process as well as control the charging time, enabling you to enjoy a smarter, faster, and safer battery-charging process.

Bicolor LED signals indicate three circumstances:
1. ) Only the red LED remains invariably bright : charging is progressing.
2. ) Only the green LED remains invariably bright : charging has been completed.
3. ) Both red and green LEDs blink alternately : there is an indeterminate fault that must be excluded from
　　the system for normal charging to proceed.

Explanation of Charging Procedure:
Stage 1: Constant Current Charging
　　　　The charger replenishes the battery with a permissibly maximal constant charging current while
　　　　the battery voltage ascends linearly from its initial level to its final level so as to abridge the
　　　　charging time.
Stage 2: Constant Voltage Charging
　　　　The charger maintains the battery voltage constant at its final level while the charging current
　　　　descends exponentially from the maximal current to a knee current and then immediately from
　　　　the knee current to nil so that the charger prevents the battery from overcharging and overheating.
Stage 3: Float Charging
　　　　The charger supplies the battery with an intermittently minimal charging current several hundreds
　　　　of nanoseconds after stage 2 finishes and will automatically terminate the minimal current two
　　　　hours after stage 3 commences.
