Hawker lithium battery packs come 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, and under the same volume, it can store more electricity and have a longer endurance. Simultaneously supporting fast charging, standard Hawker lithium batteries can achieve 2C charging, while customized ones can achieve 5C charging. The standard discharge is 0.5C, and it supports 2C discharge.  

Due to the fast charging function of the Hawk lithium battery, it is commonly used in scenarios with high automation requirements. There is no dedicated person to control the charging of the battery on site. The AGV system automatically collects power information and matches the battery charging time and current according to different states, maximizing the efficiency of AGV small vehicle operation. Generally, it works in the form of shallow charging and shallow discharging. The battery level of the car remains basically unchanged every cycle of operation, and it can achieve long-term automatic operation without human supervision.

2. Selection of Capacity for Hawker Batteries

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

Working current A=power W/nominal voltage of battery

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

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

3. Special Function Description of Hawk Battery

Hawker lithium batteries can be customized in size and functionality according to different application requirements.

The Hawk lithium battery contains a battery management system (BMS) with protection functions such as overcharging, overdischarging, overheating, and overcurrent. At the same time, it calculates the remaining battery level (SOC) internally and can provide real-time feedback to the AGV car. It supports RS485 communication, CANopen communication, AO output of battery level, and exchange of battery DIO information. AGV vehicles can obtain battery status information through interactive interfaces and control the battery according to requirements, achieving intelligent management.

For AGV automatic online charging, Hawker provides a complete solution, including online charging station, side charging mechanism, contact brush plate brush block, wireless communication module, etc.
