Maintenance of traction battery

Page 182

NOTE

◆ If the vehicle's power is on but the engine is not started, prolonged use of electrical devices in the car will cause the battery to discharge quickly. When leaving the vehicle, ensure the doors are closed and all electrical devices (such as lights) are turned off.

◆ If you have no plans to use the vehicle for more than 30 days, it is recommended to fully charge the battery and disconnect the negative terminal (except for 12V lithium batteries) to prevent over-discharge. If the vehicle has not been used for over 180 days, it is recommended to start the vehicle or use a dedicated charger according to the instructions to charge the battery. ◆ If the vehicle is used for long periods of short trips (less than 10 minutes), it is recommended to perform a vehicle start operation for at least 30 minutes once a month. ◆ If the 12V low-voltage power supply system fault indicator light is on after repairs or remote software upgrades, please start the vehicle or use a dedicated charger according to the instructions to charge the battery.

◆ Please follow the battery usage and maintenance precautions; otherwise, it may lead to early battery replacement and affect warranty coverage. If the battery appears in good condition and the usage and maintenance instructions have been followed, but product issues arise, please contact the GAC Service Center dealership for warranty service. If the battery issue is due to incorrect usage, it will not be covered under warranty, but GAC Brand will provide necessary technical support and services.

Precautions for use and maintenance of traction battery

DANGER

◆ It is strictly forbidden to remove, disassemble or modify the traction battery, or use the traction battery for other purposes. ◆ The traction battery shall be placed out of the reach of children. ◆ The traction battery shall be kept away from fire sources to avoid fires or explosion. ◆ It is forbidden to spray, trample, hit or destroy the traction battery to avoid leakage, fires or explosion of corrosive chemicals. ◆ It is strictly forbidden to touch the positive and negative poles of the traction battery case with both hands at any time. ◆ It is strictly forbidden to perform operations such as squeezing, piercing or burning that damage the battery system for the traction battery. ◆ If the traction battery suffers severe mechanical damage, resulting in the exposure of internal high-voltage components, there is a risk of violent combustion and electric shock, which may cause serious casualties and environmental pollution. ◆ The traction battery damage or electrolyte leakage may cause a fire. If it happens, it is recommended to contact the GAC Service Center immediately. Do not touch the leaked electrolyte with hands. If the skin or eyes come into contact with the electrolyte accidentally, rinse the skin or eyes immediately with plenty of water, and seek medical attention immediately. ◆ Since the traction battery pack is a high-voltage component, it is strictly prohibited to open or repair the traction battery pack by non- profession.

CAUTION

◆ T he traction battery is located at the bottom of the vehicle. During driving, take care not to have the traction battery impacted or flooded.

◆ The vehicle not used for a long period of time shall be subjected to scheduled maintenance; otherwise, the performance degradation of the traction battery will occur.

◆ I n order to give full play to the performance of the traction battery, try to avoid full charging and full discharging.

◆ T he operating environment of the vehicle shall be dry, free of corrosive, explosive or destructive insulation gases or conductive dust, and away from heat sources.

◆ Avoid frequently using the high-power DC fast charge method to charge the vehicle, because it will affect the life of the traction battery.

NOTE

◆ T he vehicle uses the traction battery to store electric energy and can be charged repeatedly. Ensure that the traction battery is fully charged before driving. During driving, the traction battery is discharged gradually. When the traction battery is low, it must be charged; otherwise, the vehicle cannot be driven. ◆ T he time required to charge the traction battery is affected by the charging power, battery SOC, battery temperature, vehicle service time, ambient temperature and other conditions.

NOTE (Cont’d)

◆ F or a new vehicle, when the traction battery is in the normal state, due to driving styles (such as frequent acceleration and deceleration), road conditions (such as long-time continuous climbing) and temperature (such as low temperature), the range of this vehicle will be appropriately reduced, which is normal.

◆ I n summer, park the vehicle in a cool environment and try to avoid direct sunlight. ◆ When the chassis area of the vehicle is bumped, it is recommended to contact the GAC Service Center for inspection and maintenance.

Precautions for LFP traction battery

If your vehicle is equipped with a LFP traction battery, please read and observe the followings.

NOTE

◆ To keep the vehicle traction battery in the best condition, please fully charge the traction battery at least once a week, and fully charge it after deep discharge once every 3~6 months. (Deeply discharge the battery to make its SOC below 10%)

◆ When the vehicle detects that you have not performed full charge operation for a long time, it may automatically perform a self-test, and the self-test process will consume some power.

Recycling of traction battery

The traction battery is a safety component. For maintenance, repair, removal, installation, reuse or disposal of the traction battery, it is recommended to consult the GAC Service Center.

When the traction battery needs to be replaced or scrapped, it is recommended to contact the GAC Service Center for

Page 184

recycling and disposal. The GAC Service Center will record the vehicle and owner traceability information through the traceability system.

DANGER

◆ If the traction battery is not handled correctly, electric shock and serious injury or even death may be caused. The removal, disassembly and discarding of the traction battery without authorization will cause pollution to the environment, and the vehicle owner shall bear the corresponding responsibility for the resulting environmental pollution or safety accidents.

WARNING

◆ When the vehicle must be scrapped, it is recommended to contact the GAC Service Center for recycling and disposal. If you come into contact with high-voltage parts, cables and their connectors and other high-voltage components when removing the traction battery without authorization during vehicle scrapping, there may be a serious risk of electric shock.
