HAWKER lithium battery EV48-20 industrial grade AGV backup carrier 48V20AH traction battery

Hawk lithium battery packs are available in 24V, 48V, 72V, 96V, etc., with 24V and 48V being widely used. The available capacities are 10AH, 20AH, 30AH, 40AH, 50AH, 60AH, 80AH, 100AH, 120AH, 160AH, 180AH, 200AH, and 300AH. The size of lithium batteries is relatively flexible and can be customized according to the space of the AGV car battery compartment. The energy density is relatively high compared to lead-acid batteries. Under the same volume, it can store more electricity and have a longer range. Simultaneously supporting fast charging, standard Hawk lithium batteries can achieve 2C charging, while customized ones can achieve 5C charging. The standard discharge is 0.5C and supports 2C discharge. 

Due to the fast charging function of Hawk lithium batteries, they are commonly used in scenarios with high automation requirements. There is no dedicated person on site to control the charging of the batteries. The AGV system automatically collects power information and matches the charging time and current of the batteries according to different states, maximizing the efficiency of AGV small vehicle work. Generally, shallow charging and discharging are used for operation, and the battery level of the car remains basically unchanged after each cycle of operation, which can achieve long-term automatic operation and unmanned operation.

2. Selection of capacity for Hawk batteries

There are two indicators for battery capacity selection: load power (W) and continuous operating time (T).

Working current A=power W/nominal battery voltage

Required battery capacity=working current A * continuous operating time T

(Note: The voltage of lead-acid batteries is calculated based on the nominal voltage of 24V or 48V. The nominal voltage of lithium batteries is calculated based on 25.6 for 24V batteries, and 48V for lithium batteries.)

3. Special Function Description of Hawk Battery

Hawk lithium batteries can be customized in size and function according to different application requirements.

The Hawk lithium battery contains a Battery Management System (BMS), which has protection functions such as overcharging, over discharging, over temperature, and over current. At the same time, it calculates the remaining power (SOC) internally and can provide real-time feedback to the AGV car. It supports RS485 communication, CANopen communication, AO output of power, and exchange of battery DIO information. AGV cars can obtain battery status information through interactive interfaces and control the battery according to requirements, achieving intelligent management.

For AGV automatic online charging, Hawke provides a complete solution, including online charging stations, side charging mechanisms, contact brush plates and blocks, wireless communication modules, etc.
