Lithium-ion (Li-ion) battery charger
Lithium-ion (Li-ion) battery chargers are designed to safely and efficiently charge Li-ion batteries and LiPo batteries, which are commonly used in a variety of applications due to their high energy density, light weight, and lack of memory effect. Green Digital Power Tech provide 10+ series 100+ standard chargers for most kinds of Li-ion and LiPo batteries voltage from 3.6V to 84V, capacity from 2Ah to 200Ah, these Li-ion chargers have following common features:
1.“Two-stage” & “Four-stage” Charging Process:
The basic Li-ion charging process is “Two stages”, CC+CV. See right curve. During CC stage, the charger supplies a constant current to the battery until the voltage reaches N*4.2V. In the CV stage, the voltage is held constant, and the current gradually decreases until the battery is fully charged.
For high-performance lithium-ion battery chargers, we employ “Four-stage” charging strategy, as figure below. The “four-stage” adds a small current pre-charge stage (which helps to extend battery life) at the beginning and add a shut-off stage at the end (which helps to enhance charging safety). Our main chargers using this 4-stage charging process.
2.Charging status display:
Our chargers offer three types of charging display methods. The basic model is using a RED/GREEN bi-color LED to indicate the charging status. For customers who need to know the state of charge (SOC) at any time, they can choose our chargers with Fuel Gauge LEDs indicator. For those who require real-time data of voltage, current, energy, SOC, SOH and timer, we offer charger products with an LCD screen display.
3.Safety protections:
Safety is a critical aspect of Li-ion battery chargers. Mian of our battery chargers provide protections against overvoltage, undervoltage, overcurrent, overtemperature, short-circuit, battery reversed conditions.
4.EMC & LVD approval:
All of our battery chargers passed basic EMC & LVD safety approval requirements. Many chargers have CE, CB, FCC, CCC, ETL, PSE, UKCA, cTUVus, SAA, KC and RCM.
