Smart Charger (15 A) for 60V/64V (20 cells) LiFePO4 Battery Pack with CAN connector (110V Only)
Product ID # 6928
Part Number: CH-LF64V15A
The CH-LF64V15A is an intelligent and multifunction EMC charger. It is designed for LiFePO4 batteries. Depending on its CAN interface and digital input port, the charger can work seamlessly with our "Energy Management System"(EMS). It will help your battery pack long life and safety.
- AC input voltage 95-130VAC 40-60Hz
- Charging voltage:50-71V (cut off voltage is 50V and 71V)
- Charging current : Max 15A Depending on the voltage of battery pack
- CAN port
- 12V digital control port
- Operation Environment
- Altitude: ≤2000 Meters
- Temperature: ‐30°C ~ 55°C
- Installation Stress: ≤ level 5
- Humidity: 5% ~ 70% RH - Non Condensing, keep away from exposure to moisture
- Storage environment: -30°C ~ 60°C - Keep away from combustible materials
- Suitable for 20 cell pack (Recommended 40Ah-100Ah battery pack)
- Smart indicator
- Interfaces with EPS Energy Management System via CAN Communication or 12V digital signal control
- Output short circuit protection.
- Over temperature protection:
- Temperature less than 85°C - Full charging power
- Temperature is 85°C to 95°C - Power reduced to 50%
- Temperature is greater than 95°C - No output
- Reverse polarity protection: charger will not turn on if the battery pack is connected backwards (or less than 5V).
- A switch on the charger marked "Override" is used to select either external or internal controlled charging.
- Override Off - Use with EMS system, either CAN or digital input
- Override On - Charger program based on pack voltage only (recommended for testing purposes only, do not use for normal charging).
- When external control is selected and a CAN signal is used, if any cell reaches the recharge set point (default 3.7V as signaled by the EMS) the charger will automatically enter the final recharge cycles.
- Recharge cycles. When the EMS detects any cell has reached the recharge set point (default 3.7V) or above, the charger reduces the charge current to zero amps for five minutes to allow the EMS to balance the battery pack. The charge will resume after five minutes at half the previous charge current and will again charge until it receives a signal from the EMS that a cell has reached the recharge set point. These recharge cycles continue until the charging current reaches the minimum charging current to complete the charging process.
- Digital alarm input:
- 0.0V - 2.0V: Charging stopped
- 2.5V - 12.0V: Enable charging or resume charging
- When both CAN and the digital control signals are available the charger is controlled by the CAN communication signal.
- Fan cooled to prevent from overheat.
- Charge terminal: Anderson SB50.
- An extra Anderson SB50 connector for DIY.Anderson plug dimension (LxWxH):1.9"(48.0mm) x 1.5"(38.0mm) x 0.6" (15.0mm) .
- CAN terminal: 5 pin male cannon plug (For BMS support)
- 1pcs 20A fuse for replacement
- Max Dimension (LxWxH): 295mm(11.6")x 174mm(6.9") x 76mm(3.0")
- Max Weight:6.0lbs 12.6Oz (3080 grams)
- Make sure charger voltage output matches to the quantity of cells in the battery pack.
- Make sure positive output of the chargers is connected to a positive connection to the battery pack, and the negative output of the charger is connected to a negative connection of the battery pack.
- After a complete charge, disconnect the power source from the charger and then disconnect the connection between the charger and the battery pack.
- A BMS system must be used during the charging process either through CAN communication or through the digital alarm input to prevent over charging.
- Always place the charger in well-ventilated, dry environment and indoor use only.
- Please plug in AC power first, then connect the battery to the charger, otherwise, there is no output from the charger.
