Solar regulated direct charge uninterrupted, battery  voltage controller

Simple BMS Controller for Solar Stabilized Charging

Customized charging voltage for lithium batteries, and normal charging and stopping battery voltage V1
Solar voltage stabilized direct charge uninterrupted, battery voltage control controller
SunReadFarm Technology Co., Ltd established in 2018, is located in Taichung City, Taiwan.
Our company focuses on the R&D, production and sales of controllers for solar regulated charging. A smart solar, mobile EV charging controller with a new architecture.

1.The battery can be charged up to a single solar voltage stabilized charging and a simple BMS controller.
2.The normal battery voltage value is V1, the battery power consumption V1 voltage

    drops, the charging switch is turned on, and the battery is charged.
3.The solar energy stabilized direct charge is uninterrupted, the battery voltage is  controlled,
   and the charge reaches the specified normal battery voltage value V1,  and the charging is stopped.
4.The battery is charged only when it consumes power, and the battery does not enter

    the floating charge state and warms up.
5.Suitable for lithium, lead-acid and other types of batteries, high-frequency discharge,

   can immediately recharge the battery. High-efficiency direct charging reduces battery DoD.
6.It can be widely used in EV vehicles, car charging generator backup,

   outdoor power generation, _ charging is safer.
7.Added multi-function mode, power off when the battery is fully charged.

Applied to lithium battery:        maximum chargeable voltage when connected in series = 4.2 X N
                                                                                                       Normal voltage can be set = 3.7 X N=V1
                         As soon as the normal battery voltage V1 drops, all solar current will be charged
                                                                              Charge up to the specified voltage value, stop charging
                                                                                                       battery full charge stop set=4.2X N -0.1Vtg
                     Solar charging current / lithium battery rechargeable current = 0.1 ~ 0.9 (small value, high safety)

       Equipped with self-developed remote battery voltage detection technology, the controller can hing frequency detect the battery voltage when the voltage is regulated and directly charged. Supports wires up to five meters in length, and the battery can accurately control the voltage to the second decimal place.
Battery two step protection :

  1. Charge the battery not to exceed the chargeable charging voltage, and the battery will not overvoltage.
  2. Charge only when the normal battery voltage is drained The battery is never under pressure.
  3. Therefore, it can reduce the battery DoD and increase the temperature of the battery after high current output. Prolong battery life.Increase the running distance of the equipment.

EX: Solar current 3A is ready. When the accelerator of the EV car accelerates, the battery voltage V1 drops       and the charging switch opens.
       The motor needs 5 amperes. At this time, the solar current 3A is charged into the battery and used first. The battery only needs 2 amperes of current to the motor.
       The smart control of the normal battery voltage value V1+ charging switch can prevent the battery from being in a high-frequency power supply and battery fully charged state when the EV car stops and goes.
       It is easy to damage the battery.
       This solar charging method can provide supplementary power as soon as possible after the battery is discharged. It is better than any solar controller on the market. It is more suitable for use in EV vehicles.

This product has passed the Ce FCc electronic product safety certification, just connect the positive and negative power cords of the solar panel to the controller,Convert it to a suitable charging voltage. Then connect the positive and negative wires of the battery terminal to the controller_easy to install.
