2012 2011 Toyota Prius Hybrid Battery Replacement 201.6V Long Life Circle

Hyno Energy. HEV Battery Replacement For Toyota Prius 3rd Gen. (2010-2015). 6500mAh 201.6V, Long Life Circle

Hybrids are designed so that all the “High Voltage” is in its own closed circuit, totally separate from the 12v circuit, totally separate from the vehicle chassis. The two cables leaving the high voltage battery are the battery positive and battery negative cables. They’re heavily insulated from chassis ground. The Inverter, the 3 phase cables going to the hybrid motor(s), and the motors themselves are all very heavily insulated from chassis ground. This is to protect the occupants of the vehicle, and the public in general, from electric shock. There is a minimum specification for this resistance to chassis: it must be at least 500 ohms per 1 volt of high voltage. For example, on a system that uses 300 volts, the spec would be 150,000 ohms minimum. Realistically, most OEs insulate much more than is needed, and the “Isolation Fault” codes tend to set long before it reaches this minimum limit.

Cautions of Battery Pack Transportation and Storage

1. Avoid violent vibration and external force impact, don’t cast, roll, invert, extrude, and stack too high during handling and transportation of battery pack.
2. Protect the battery pack from rain during the transportation, and the ambient temperature is not over 55℃.
3. Store the battery pack in a cool and dry place and the temperature range is 5-25℃ when you are not using it.

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

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.
