Escalade hybrid

How to charge escalade hybrid at low voltage?

You can use a portable charger to charge, but it is not enough to rely on the on-board generator to charge. For example, the charging method of 12V80Ah is: constant voltage and current limiting charging,14.8v and 20 a constant voltage and current limiting charging 16 hours, and then 4A constant current charging for 4 hours, totaling ***20 hours. Escalade hybrid is equipped with a dual-mode hybrid system. The traditional 6.0LV8VORTEC all-aluminum engine is equipped with ETC electronic throttle control, VVT variable valve timing system and AFM intelligent fuel management system, which can intelligently choose whether the engine works in 4 cylinders or 8 cylinders. The maximum power at 5 100 rpm can reach 248 kW (332 HP), and the maximum torque at 4 100 rpm can reach 498 Nm. In order to effectively control fuel economy, the engine adopts AFM intelligent fuel management system. During the driving process, the system determines that it is low-load driving, and the driving computer changes the engine from 8 cylinders to 4 cylinders. After switching to cylinder 4, the electrical system will start working immediately, which can prolong the driving time in cylinder 4 and achieve the purpose of saving fuel. With this system, it is really helpful to save fuel in the case of traffic congestion or slow driving. In terms of electrical system, the escalade hybrid vehicle is equipped with two 83kW motors, which are integrated in the EVT electronic continuously variable transmission. Electricity is stored in a set of 300 volt Ni-MH batteries under the car body, and charged by the power or energy recovery system of the gasoline engine when braking. When the vehicle needs to slow down or brake, the motor can work in the opposite direction to brake the vehicle through the resistance effect. At this time, the motor can be used as a generator to convert braking energy into electric energy and charge the battery. If it is hard braking, it will increase the brake disc system of the car and carry out normal braking. The two braking forces are braked together to improve the braking efficiency.
