Hyno energy. HEV Battery Replacement For Lexus GS450H (2009-2011). 6500mAh 288V

Most electric vehicles have a traction battery which is in addition to the standard 12 volt battery that is used to start the car engine. Traction batteries also convert chemical energy to supply electrical energy but operate at higher voltages and often are monitored by the PCM (Powertrain Control Module).

A new battery has a specified capacity to provide power. This capacity is referred to as the cranking amps rating of the battery. As a battery ages, the actual amps that a battery can supply becomes lower than its original rating Once the cranking amps fall below a critical threshold, it will be difficult or impossible to start your car.

Maintenance regulations (Maintain the whole battery pack, and cool with a fan during the charge and discharge process)

The SOC of our battery pack is 60%~80% when leaving the factory, in long-term storage, battery should be stored in a charged state (usually the SOC is 80%). Have a charge and discharge maintenance to battery pack when the storage time is over 6 months or battery module’s voltage is 15V,to prevent the battery performance’s decline caused by the self-discharge. The maintenance regulations are as follows:

1. Discharge: 2A discharge to 204V (that is to say: single cell 1.0V)
2. Interval: 30 minutes
3. Charge: 1.3A charge for 5 hours (voltage ≥ 306V, -ΔV ≥ 0.2V and temperature ≥50℃)
4. Interval: 1hours
5. Discharge: 2A discharge to 204V (that is to say: single cell 1.0V)
6. Interval: 30 minutes
7. Charge: 2A charge for 2.4 hours

Cautions of Battery Pack Transportation and Storage

Avoid violent vibration and external force impact, don’t cast, roll, invert, extrude, and stack too high during handling and transportation of battery pack.

Protect the battery pack from rain during the transportation, and the ambient temperature is not over 55℃.

Store the battery pack in a cool and dry place and the temperature range is 5-25℃ when you are not using it.

Installation Cautions of battery pack

Notes: Installing this product should only be attempted by a qualified technician, the voltage of the battery pack is very high, which has the shock hazards, so when installing the battery pack, you should wear insulating gloves and use insulated handle tools.

1. Please operate according to assembly manual during the installation of Prius battery pack.
2. Do not mix our battery modules with those of other manufacturers, or new battery modules in use with semi-used battery modules, and don’t mix battery modules within a battery pack with those in other battery pack.
3. Don’t twist and bend battery modules and accessories when assembling battery pack.
4. Don’t connect the anode and cathode of battery module in reverse when assembling battery pack, to prevent short circuits.
5. Fasten bolts and nuts with appropriate torque, avoid loose connection or damaging other accessories with too big torque.
