Lithium-ion battery charger covers 14 cells

The 4040LI uses a 3-stage charging profile with a microcontroller to maximise battery performance.

The new charger is also capable of waking up deeply discharged batteries and to soft-start charging with low current until voltage is normalised.

This model is well suited for a wide variety of applications from medical to consumer.

Owners of the new 4040LI charger will receive optimised uptime and turnaround for battery-powered equipment such as medical devices, telecom, energy storage and power-assisted E-Mobility products. The 4040LI is medically certified according to EN 60601-1 ed. 3.2 and Home Healthcare EN 60601-1-11.

It is also UL-approved and has 12 standard versions initially available for charging batteries from 3 cells (9.0A/12.6V) to 14 cells (2.0A/58.8V).

Custom units are available upon request as well.

Alternative chargers that terminate the charge on reaching the battery’s threshold voltage can shorten charging time but always leave some capacity unfilled.

The 4040LI’s 3-stage charging first restores the full 4.2V/cell battery voltage and then applies the saturation charge needed to fill up the battery completely. This ensures the longest possible battery run-time and charging finishes when the battery is full.

The charger also features a single 3-colour LED indicator light for charge, error- or standby status, and a wall-mount bracket is available.
