SMPS Battery Charger

SMPS Battery Charger • A typical Switched Mode Power Supply incorporates a frontend AC-DC rectifier to generate an unregulated DC input voltage. • High power & high frequency MOSFETs/IGBTs then switches ON/OFF the unregulated input DC Voltage at a very high frequency (say 80Khz) at the primary of a ferrite transformer. • This high frequency ferrite transformer isolates, steps down and converts this square wave DC to square wave AC output. • It is then rectified & filtered to generate a smooth ripple free output DC voltage. • Pulse Width Modulation technique is generally employed to regulate the SMPS output.

SMPS Battery Charger

Product overview

Description

● Battery Charging is a complex electro technical process, in which the discharged electrical energy of a battery is replenished from the electrical utility service.

● Quality of the charging process is critical to the health & longevity of the battery. Here quality of the BATTERY CHARGER or quality of the BATTERY CHARGING-PROFILE plays a vital role in life & performance of today’s industrial BATTERIES.

● Conventional lead acid batteries are fast getting replaced by Lithium-Ion and & Lithium-ferro-phosphate batteries because of its long life, reduced size and weight.

● Lithium Batteries, due to its compactness and long life, are used in mobility applications, mainly in the Battery-operated EV sectors. And Lithium Batteries can endure up to5000 cycles.

● SMPS based automatic Battery Chargers are compact, economic and energy efficient.

● ESI SMPS Chargers are designed to provide a perfect balance between maximum utilization of battery capacity and safe charging. Intelligent techniques are implemented in ESI SMPS Battery Chargers with cutting-edge microcontrollers.

● ESI make Li-ion battery chargers are designed to handle the precise charging profiles that lithium-ion cells demand.

Frequently Asked Questions

1) Is the charger suitable for use as a DG set battery charger?

Absolutely. SMPS chargers are well-suited for DG set battery charger applications, keeping standby/ backup batteries in optimal condition. Features such as automatic boost to trickle changeover and CC-CV charging mode keep your DG set Batteries healthy and ready for subsequent operations.

2) Is the charger safe to be used as a Li-ion battery charger?

SMPS chargers are designed to meet the demands of modern lithium-ion batteries. ESI make Lithium-ion Battery Chargers comes with built-in intelligent microcontroller-based controls that charge batteries without hurting/ compromising battery longevity.

3) How does an SMPS-based VCB battery charger differ from a conventional one?

An SMPS-based VCB battery charger is notably more compact and efficient. It is also more cost-effective than traditional SCR-based alternatives, costing around 40% less. They deliver a cleaner output with low ripple, perfect for sensitive substation equipment that needs uninterrupted battery backup.
