5. New Energy Power System 5-3 Energy storage system Energy storag e system 5.1 Energy storage system 5.1.1 Precautions WARNING: 1. Do not reuse the collided high voltage battery. Collision may lead to damage and crack of partial parts inside the high voltage battery, or even short circuit of the high voltage battery and other extreme situations. 2. Prevent the high voltage battery from being soaked, which may lead to internal short circuit, loss of circuit protection function and abnormal chemical reaction of the high voltage battery. 3.

Do not bump or hit the high voltage battery during assembly to avoid deformation of the housing and its internal structure, which may lead to loss of protection function of the internal circuit of the high voltage battery. 4. Welding on the housing is prohibited. The applied voltage to the high voltage battery may cause the loss of protection function of its internal circuit. 5. This manual does not necessarily include all items required for vehicle repair and maintenance. It is intended for use by personnel with professional skills and qualifications.

Repair or maintenance performed by technicians who have no professional skills or qualifications and rely only on this manual or fail to use appropriate equipment or tools, will cause injury to themselves or the surrounding personnel and damage to customer's vehicle. 6. To avoid damage to vehicle as a result of dangerous operations, please observe the following rules: a. The contents of this manual must be read thoroughly. b. The methods provided in this manual are quite effective for vehicle maintenance and repair. When performing repairs following the procedures prescribed in this manual, always use the SST.

In the event of using non-designated special tools and repair methods, you must ensure the safety of the technician before start and make sure no personal injuries or damages to customer's vehicle will be caused. c. If parts need to be replaced, replace parts with the same part number or use equivalent parts. Do not use inferior parts. d. In order to effectively avoid possible personal injury during repair or maintenance, as well as vehicle damage caused by improper operation or potential hazards that may make the vehicle unsafe, you must earnestly observe the “Warning” and “Caution” in this manual. In addition, the contents of “Warning” and " Caution " in this manual are not exaggerated.

Violation of these instructions may lead to dangerous consequences. e. All related operations of the HV system (e.g., maintenance, or repair of the electrical system) of the vehicle can only be performed by professionals trained in HV electrical knowledge. 7. Keep the removed high voltage battery away from water or high humidity environment. Water and vapor may lead to reduced insulation and short circuit of the high voltage battery, thereby resulting in risks of electric shock, fire, etc. 8. Improper scrapping or random discarding of the vehicle and its high voltage battery may cause electric shock and other accidents.

Therefore, the high voltage battery should be delivered to designated recycling location by an authorized dealer. VOYAH FREE

5-4 Energy storage system 5. New Energy Power System 5.1.2 Introduction to structure and principle BMS controller BMS is used to take control of the battery pack, including battery safety, SOC algorithm, charge and discharge control commands, parameter monitoring, etc. BMS detects the total voltage, total current, cell voltage, temperature and other information of the battery pack, and sends this information to CAN network. BMS performs equalization control of the battery pack to ensure proper working of the battery pack. BMS can carry out thermal management of the battery pack, including heating and cooling control.

Total positive and negative relays The relay connects or disconnects the battery pack power circuit and check the relay contacts for sticking. Battery pack control BMS checks the charging and discharging status of the battery pack, and calculates the battery pack power status. It also controls the charging and discharging status and calculates the power of the battery pack. The battery pack enables the vehicle to drive, accelerate and decelerate by means of charging and discharging. The battery pack sensor detects signals such as voltage, current, and temperature, and transmits the signals to VCU. The battery pack has an insulation detection function. VOYAH FREE
